Level Measurement Device Comparison

Level Measurement Device Description Probe Diameter Tape / Cable Lengths
101 P7
Water Level Meter
solinst model 101 p7 water level meters Manually measure depth to water using flat tape marked each mm or 1/100 ft. 101 P7 Meters use laser-marked flat tape. Measure total well depth with a P7 Probe (submersible the full length of hte tape). 16 mm (5/8") 30 - 600 m
(100 - 2000 ft.)
101 P2
Water Level Meter
101 P2 Meters use heat-embossed polyethylene tape. The P2 Probe is simple to clean and repair. 14 mm (0.55") 30 - 300 m
(100 - 1000 ft.)
101D Water Level DrawDown Meter solinst model 101d water level drawdown meter Manually measure depth to water and monitor drawdown using laser marked flat tape, laser-marked each mm or 1/100 ft. Probe is pressure-proof the full length of the submerged tape. 16 mm (5/8") 30 - 600 m
(100 - 2000 ft.)
101B
Water Level Meter
solinst model 101b basic water level meter Manually measure depth to water using heat-embossed polyethylene flat tape, marked every centimeter. The P1 Probe is leak-proof. 12.7 mm (1/2") 30 m, 60 m, 100 m
102
Water Level Meter
solinst model 102 water level indicators Manually measure depth to water using narrow cable, laser-marked each mm or 1/100 ft. P4: 4 mm (0.157") P10:10 mm (3/8") 30 -300 m
(100 - 1000 ft.)
102M
Mini Water Level Meter
P4: 4 mm (0.157") P10:10 mm (3/8") 25 m
(80 ft.)
104 Sonic Water Level Meter solinst model 104 sonic water level meter Uses sound waves to detect the depth to static water level without lowering the probe down the well. 16 mm (5/8") 600 m (2000 ft) Detection Range
105 Well Casing & Depth Indicator solinst model 105 well casing and depth indicator Detect where metal well casing starts and ends, and measure the total depth of a well or borehole. Measurements are taken using flat tape laser-marked each mm or 1/100 ft. 22 mm (7/8") 30 - 600 m
(100 - 2000 ft.)
201 Water Level Temperature Meter solinst model 201 water level temperature meter Manually measure water level and temperature. Water Level measurements are taken from flat tape lasermarked each mm or 1/100 ft. 16 mm (5/8") 30 - 600 m
(100 - 2000 ft.)
107 TLC Meter solinst model 107 tlc meters Manually measure water level, temperature, and conductivity. Water Level measurements are taken from flat tape lasermarked each mm or 1/100 ft. 19 mm (3/4") 30 - 300 m
(100 - 1000 ft.)
122 Interface Meter solinst model 122 oil water interface meters Manually measure water levels and detect oil/water interfaces. Allows measurement of DNAPL or LNAPL layers. Using the standard 122, levels are taken from flat tape laser-marked each mm or 1/100 ft. Using the 122M, levels are taken from cable laser-marked each mm or 1/100 ft. Intrinsically Safe and ATEX Certified. 16 mm (5/8") 15 - 300 m
(50 - 1000 ft.)
122M Mini Interface Meter 16 mm (5/8") Cable: 25 m
(80 ft.)
103 Tag Line solinst model 103 tag lines Manually measure well depths using durable cable, laser-marked every 5 cm or 1/10 ft., or flat tape lasermarked every mm or 1/100 ft.

(Also a marked support line for samplers, packers, and dataloggers)
19 mm (3/4") or 13 mm (1/2") 30 - 300 m
