Model 101 Water Level Meters

The 101 Water Level Meter is very sturdy and gives consistently accurate water level measurements in wells and boreholes.
The tape is permanently marked each 1/100 ft or each millimeter, in lengths up to 6,000 ft (1,800 m). The tape has stranded stainless steel conductors for long life and easy repair. A dog-bone tape design reduces adherence to wet casing. Probes have recessed sensors to minimize false signals.
The well balanced reel has a carrying handle, an easy-access battery drawer, and an excellent brake. A 9V battery powers the buzzer and light, which activate when static water is reached.
The Mini 101 Water Level Meter is a very compact and easy to carry meter available in 65 ft (20 m) lengths. A choice of probes with extra weights has a maximum diameter of 0.313” or 0.375” (7.9 mm or 9.5 mm). The narrow tape is accurately marked each 1/100 ft or 1 mm. It is ideal for use in any narrow diameter application, where high accuracy is desired.
Power Reels for Water Level Meters can be very useful. They allow faster and less strenuous operation of meters with long tape lengths. They are available in a variety of sizes to suit the cable length and are designed to operate with 110 volt power. They are also useful for operating pumps with long lengths of tubing.

Level Measurement

TLC Meter

The 107 TLC Meter (Temperature, Level, TLC Meter Conductivity) displays accurate measurements of conductivity and temperature on an LCD display that rotates for ease of use. Water levels and probe depth measurements are read off the accurately marked Solinst flat tape.
It is ideal for profiling salt-water intrusion, road salt impairments, tracer tests and to give a general indication of chemical contamination levels.
The TLC Meter uses a ‘smart’ conductivity sensor with platinum electrodes to read conductivity from 0 – 80,000µS with an accuracy of 2% of reading or better. Readings stabilize in 20 seconds.
The flat tape is permanently marked each 1/100 ft or millimeter and is available in lengths up to 300 ft (100 m). The meter comes with a carrying bag and tape guide. The LCD screen rotates for easy reading.

Model 102 Water Level Meter

The 102 Water Level Meter is low cost and designed for use in narrow diameter tubes, as small as 3/8" (10 mm). The stainless steel coaxial cable has a heavy duty polyethylene jacket and markings permanently bonded to the cable every 5 ft or 1 m, and 1 ft or 0.5 m. Narrow diameter probes in 1/4” or 3/8” (6 mm or 10 mm) are available with segmented weights to aid deployment.
When the probe enters water, the water completes an electrical circuit powered by a 9V battery, sending a signal back to the reel where a light and clearly audible buzzer are activated. The water level is then determined by taking a reading off the cable at the top of the borehole, casing or tube, and then measuring off to the nearest mark.

Interface Meters

The 122 Interface Meter measures product level and thickness accurately to 1/100 ft or 1 mm. It measures both floating and sinking hydrocarbon, non-aqueous product layers.
The 122 is certified safe for use in explosive environments by the Canadian Standards Association (CSA - Class 1, groups C & D).
A steady tone and light indicate product and intermittent signals indicate water. The Solinst Interface Meter is rugged, field durable and is easy-to-use. A carrying bag and tape guide are included.
The 122M Mini Interface Meter offers a more portable version of the larger. It is small enough to fit in a backpack, yet rugged and reliable. Available in 65 ft. or 20 m lengths.
The Mini gives highly accurate readings of LNAPL or DNAPL product level and thickness in wells and tanks and is CSA approved. The 9V battery offers approximately 300 hours of use.

Tag Line

The 103 Tag Line is used to measure the depth to the top of backfill sand or bentonite layers during the completion of a well and to measure the depth to the bottom of a well.
The Tag Line uses polyethylene coated, permanently marked, stainless steel wireline and a choice of stainless steel weights, mounted on a Solinst reel.
Low-profile markings are bonded in place every 5 ft or 1 m, with more markings available as an extra. Ideal for use when installing Solinst 403 CMT Multilevel Systems.
The weights can be clipped on and off the cable. This allows for the reel mounted, marked cable to be used as a support cable i.e. for bailer deployment.

Telemetry Systems

The 9100 Solinst Telemetry Systems (STS) are designed specifically for use with Solinst Leveloggers and Rainloggers. Telemetry offers 2-way communication between field-located Leveloggers, Barologgers and Rainloggers and a computer Home Station. The STS is designed to save costs by enabling the self-management of data, as well as remote collection of the data. The STS and its software are suitable for both large and small systems.
Solinst offers GSM and CDMA digital cellular, radio and landline telemetry options, and satellite telemetry options.
The setup software has a simple system for identifying each individual logger and setting up of automatic dialing schedules. Alarms for high and low water level and authority levels restrictions can be set. Power requirements are kept to a minimum since it uses low power electronics and no power at all in standby mode. Downloaded data can be processed using the standard Levelogger Software or imported to other programs as desired.

The 9200 RRL Radio Telemetry System offers a very simple, inexpensive method of local telemetry. The wireless system is designed to collect real-time data from Leveloggers, Barologgers and Rainloggers and communicate over distances up to 1000 ft (300 m). Distances can be increased by using some radios as repeaters.

3002 Rainlogger

The 3002 Rainlogger is designed for use with Levelogger Software and most standard tipping-bucket rain gauges, with a reed switch output. The rainfall level per sampling period and a five-minute maximum rainfall are logged in a non-volatile memory, with up to 40,000 readings. Linear sampling can be set from 1 to 99 minutes/hours.
The Rainlogger resolution is dependent on the rain gauge used, but is typically from 100 to 200 •m (0.004 to 0.008 in). Logged data can be downloaded direct to a PC or to a hand-held Leveloader Gold. The Rainlogger has a 10-year battery, optional SDI-12 protocol to interface with third-party data recorders, and is compatible with Solinst telemetry systems.

Sampling Pumps and Accessories

The 407 Integra® Bladder Pump has a Teflon® bladder guaranteed for 10 years. Solinst offers 316 stainless steel Integra pumps in diameters of 1" and 1.66" (25 mm and 42 mm) and PVC Integra Pumps in 1.66" (42 mm). They are ideal for low flow sampling but can also be used for regular flow sampling. Maximum lift capabilities are 500 ft (150 m) with the stainless steel models and 100 ft (30 m) with the PVC.
Dedicated systems may be purchased pre-assembled for easy installation, complete with well caps and tubing. Portable systems are also available as illustrated. Cart-mounted portable pumps have pneumatic tires and a lowering guide for easy use. LDPE bladders now available for disposable short term applications.

The 408 Double Valve Pump (DVP) is similar to the Bladder Pump, but without a bladder. It is a gas drive pump suitable for applications of almost any depth and narrow diameters. It is available in stainless steel in 1.66" or 5/8" diameter (42 mm or 16 mm) and in PVC in 1.66" (42 mm). Portable and dedicated versions are available. The DVP 1.66" (42 mm) converts easily into a Bladder Pump, if desired.
All pumps can be quickly disassembled for decontamination, and are operated using the Model 466 Electronic Control Unit below. Pumps may be fitted with pneumatic/hydraulic packers to reduce purge volumes.
(See Model 800 Packers.)

The 408M Micro Double Valve Pump has a remarkably small and flexible design. It is a pneumatic pump similar to a Bladder Pump, but using coaxial Teflon tubing with stainless steel valves & filter for high quality sampling.
It is small enough to fit in 1/2" (13 mm) tubing and all channels of the Solinst CMT System. The Micro DVP is ideal for low flow sampling in narrow applications and operates to depths of up to 200 ft (60 m). A flow rate of 20 – 200 ml/min can be obtained.

The 466 Electronic Control Unit controls the supply of compressed gas to pneumatic pumps including the Integra Bladder Pumps and Double Valve Pumps. The Control Unit uses simple, preset sample modes to allow easy selection of the desired sample rate, with controls for further finetuning. The sampling rates may be selected to ensure a representative low-flow sample at 100 ml/min or less. Higher flow rates for purging may also be chosen. The Electronic Control Unit is available in 160 psi and 250 psi models. The Controller uses 8 AA batteries, that allow continuous operation for up to 30 hours, and can be easily replaced in the field.
The 12 Volt Compressor is lightweight and compact, ideal for field use. It uses any 12 volt DC power source, such as a car or truck vehicle battery, and comes with alligator clips. The compressor operates at 125 psi and is equipped with a 2 US gallon (7.6 liter) air tank which is rated to 150 psi.

The 410 Peristaltic Pump operates to the suction lift limit, allowing vacuum pumping or pressure delivery of liquids or gases. It is ideal for vapor or water sampling from shallow wells and surface water. The Solinst Peristaltic Pump has reversible flow and a variable pumping rate depending on use of either 3/8" or 5/8" (10 mm or 16 mm) silicon tubing.
The power cable is fitted with alligator clips and uses any 12 volt external DC supply. It can deliver from 40 ml/min. almost to 3.5 liters/min. The pump is very compact and easy to use, with a handle and one easy-access control on the top of the pump. The metal case is water resistant and has no grates or openings.

The 425 Discrete Interval Sampler is excellent for obtaining representative groundwater samples from below product layers, or for sampling within floating or sinking product layers, and also for sampling at discrete depths in a well. The reel mounted stainless steel sampler has a convenient sample release device and is easy to decontaminate without the need for tools. It is pressurized with a hand pump before entering the well. No water flows through the sampler on the way down the well. When the pressure is released, the sampler fills directly from the sampling zone.

The 404 WaTerra Pump is ideal for dedication. The system includes a simple footvalve and length of polyethylene tubing, which is very inexpensive. Sampling to depths of 100 ft (30 m) can be performed by hand, or with the inexpensive hand pump handle, and to 250 ft (75 m) with an electric or gasoline pump controller. The Waterra Pump is suitable for purging, sampling and developing wells. It easily handles heavily laden, silty water. A variety of footvalve sizes, surge blocks, filters and 4 tubing sizes are available.

Multilevel Systems

Why Multilevels?

Contaminant plumes usually display considerable variations in concentration over small vertical distances. Conventional monitoring wells can be ineffective in defining plumes because long well screens mix water samples of varying concentrations. Worse yet, ambient flow of groundwater in conventional monitoring wells can spread contamination within the aquifer.
Multilevel systems provide groundwater samples from multiple depth-discrete levels (ports) optimizing the amount of information obtained in a single monitoring hole. A transect of Multilevel Systems across a site more clearly identifies the area of maximum concentration.

The 403 CMT® Multilevel System* provides the simplicity and low cost of a bundle-type installation, with the benefits of backfilling or sealing around a single tube.
The CMT offers low cost multilevel monitoring up to 7 zones in a single tube, with no joints. The narrow 3-Channel System is ideal for installation using direct push rigs. For such installations, bentonite and sand cartridges are available to give reliable seals between zones. Fast installation ensures the hole is not left open to deteriorate or contaminate.
The CMT System uses continuous polyethylene multichannel tubing which is custom-built on site with screened intervals at desired sampling zones. Reliable seals and sand packs can be placed around the single tube using standard backfill methods, or using pre-formed cartridges in the 3-Channel System.
The CMT Multilevel allows detailed 3-D water levels and water samples at an affordable cost. Detailed transect monitoring of plumes using CMT Systems enable zones of high concentrations to be identified quickly, simply, and at less cost. This gives data that allows better decision-making.
Water levels can be accurately established and samples taken using small diameter portable equipment available from Solinst. If preferred, a sampling tube can be dedicated to a channel that is not needed for water level monitoring. Special wellhead seals are also available to allow vapor sampling in the system.

The 401 Waterloo Multilevel System* allows detailed groundwater monitoring from many zones in one borehole, without cross-contamination between monitoring zones. When a number of systems are used at one site, a detailed 3-dimensional picture can be obtained for a more accurate assessment of hydrogeological parameters.
In 3" to 4" bedrock boreholes and pre-cased wells, Waterloo packers give permanent seals to isolate discrete zones. In overburden, Systems can be placed within pre-cased holes with packers, or installed using standard tremie placement of bentonite seals and sand packs.
The System is modular to allow ports to be located accurately at desired monitoring zones. The zones are permanently isolated by the packers or seals and each port is individually connected to the surface. Ports can be fitted with dedicated Transducers, Bladder Pumps and/or Double Valve Pumps. Alternatively, a port may be fitted with a monitoring tube that is left open for use with narrow diameter portable equipment, such as the 102 or Mini 101 Water Level Meter and a narrow diameter Waterra Pump, a Peristaltic Pump or the Micro Double Valve Pump.
Ports, packers and casing lengths are assembled, as needed, into a water-tight PVC or stainless steel casing string. The modular Waterloo System allows complete customization to each application. Systems can be installed on an angle or vertically. A drilling rig is not necessarily required during installation. Monitoring is fast and efficient, especially if dedicated equipment is used.
Removable multilevels are also available. They are similar in design, but use hydraulic pneumatic packers. For shorter term projects these systems are excellent. Multilevel Systems can greatly reduce the cost of groundwater monitoring.

Remediation & Monitoring Instruments

The 703 Waterloo Emitter™ is a simple, low cost device for the controlled release of oxygen or other amendments to encourage and sustain the growth of microorganisms required for in-situ bioremediation of contaminated groundwater.
Ideal for the diffusion of oxygen to enhance the bioremediation of BTEX and MTBE. Emitters provide immediate bioavailability of molecular oxygen for aerobic biodegradation enhancement, with no loss of amendment gas due to bubbling.
Available to fit 2", 4" and 6" (50, 100 and 150 mm) wells and boreholes, the Emitters are easy to install and remove. They do not require constant monitoring and attention or electricity.
The 2" (50 mm) system can also be installed through larger direct push casing. Almost any appropriate fluid (gas or liquid) can be used with the Waterloo Emitter diffusion technology to apply specific chemicals to a groundwater plume.

The 615 Drive-Point Piezometers are costeffective for initial site investigations, plume delineations, and as low-cost mini well points. They are excellent for groundwater or soil gas sampling, underground storage tank monitoring, and as sparge points. The stainless steel piezometer point has a 50 mesh screen, uses 3/4” NPT pipe and a sampling tube if higher quality samples are required.

The 601 Standpipe Piezometer is a low cost piezometer, excellent for taking water level measurements. The PVC tip is suitable for pushing into very loose sands at the base of a borehole, or for backfilling in place within test pits and pre-augered holes. It uses a porous polyethylene filter inside a perforated PVC tip which connects to the surface with 3/4" (19 mm) ID PVC extensions.

The 660 Drive-Point Profiler allows collection of groundwater samples from multiple points, at discrete zones, in a single drive. This allows a detailed vertical profile with only one drive of the rig. The profiler tip is connected to a Peristaltic Pump which flushes the profiler tip with de-ionized water during driving to prevent cross contamination and is reversed to obtain a sample. It allows detailed plume delineation quickly and inexpensively. An expendable grout tip is available to allow easy decommissioning.

The 429 Stainless Steel Point-Source Bailer has an easy sample release device and dual check valves top and bottom. The check valves prevent water at other depths from mixing with the sample during retrieval.
Point-Source Bailers are available in 0.5", 1", 1.5" and 2" diameters (12.7, 25.4, 38.1, 50.8 mm), and lengths from 1 ft. to 4 ft. (305 mm and 1220 mm). The Solinst Tag Line with marked cable can be used to facilitate the raising and lowering of the bailer.

The 428 Disposable Bailer is a low cost bailer made of translucent HDPE (high density polyethylene). The standard bailer is 1.5" x 3 ft (38 mm x 915 mm) and holds more than one liter. A narrow 3/4" (19 mm) bailer holds over 250 ml.
For ease of use, the top and bottom of the bailer are tapered and a sample release device is included. An optional low flow Sample Release Device is available for the standard 1.5" (3.8 mm) bailer.

The 800 Low Pressure Packers are simple, inexpensive and inflate with a hand pump. They come as single or straddle packers and can be lowered into the well on low density polyethylene tubing or a rigid PVC pipe. The gland is made of black carbon reinforced rubber.
The packers are available in sizes to fit wells and boreholes from 1.9" – 4.5" (48.3 – 114.3 mm). The smaller packer has a gland length of 23" (584 mm) and the larger 30" (762 mm). Maximum pressure for any packer is 50 psi (345 kPa). The Solinst Tag Line can be used as a marked safety line, if desired.
