absolute pressure (water column pressure + barometric pressure) over time. The Barologger functions and communicates similarly to the Levelogger, but is used above the water level to record ambient barometric pressure in order to barometrically correct data recorded by the Leveloggers. Typically, one Barologger can cover a radius of 30 km (20 miles) and\/or every 300 m (1000 ft) elevation change.  <\/li>\n<li>See Technical Bulletin:<span> <\/span><a href=%22https:\/\/www.solinst.com\/onthelevel-news\/water-level-monitoring\/water-level-datalogging\/barometric-compensation-and-the-importance-of-barometric-data\/%22 title=%22Importance of Barometric Compensation and Barometric Data%22 data-uw-rm-brl=%22PR%22 data-uw-original-href=%22\/onthelevel-news\/water-level-monitoring\/water-level-datalogging\/barometric-compensation-and-the-importance-of-barometric-data\/%22>Barometric Compensation and the Importance of Barometric Data<\/a><\/li>\n<\/ul>\n<p>&#8221; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; parentOrderClass=&#8221;dsm_faq_0&#8243;][\/dsm_faq_child][dsm_faq_child dsm_title=&#8221;What is the difference between absolute and vented (gauged) pressure sensors?&#8221; dsm_content=&#8221;<\/p>\n<ul>\n<li>See Technical Bulletin:<span> <\/span><a href=%22https:\/\/www.solinst.com\/onthelevel-news\/water-level-monitoring\/water-level-datalogging\/absolute-vs-vented\/%22 title=%22Absolute Water Level Dataloggers Compared to Vented Water Level Dataloggers: Understanding the Difference%22 data-uw-rm-brl=%22PR%22 data-uw-original-href=%22\/onthelevel-news\/water-level-monitoring\/water-level-datalogging\/absolute-vs-vented\/%22>Absolute Vs Vented Water Level Dataloggers \u2013 Which Method Is Right For Your Project?<\/a><\/li>\n<\/ul>\n<p>&#8221; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; parentOrderClass=&#8221;dsm_faq_0&#8243;][\/dsm_faq_child][dsm_faq_child dsm_title=&#8221;How do I select the correct pressure range of Levelogger for my application?&#8221; dsm_content=&#8221;<\/p>\n<ul>\n<li>The choice of pressure range largely depends on the accuracy of the water level required and the desired submergence depth. The selection, however, should be based on the maximum anticipated water level fluctuation. <\/li>\n<li>Example: The Levelogger 5 M5 is designed for 5 metres or 15 feet submergence and provides a typical water level accuracy of \u00b13 mm (0.01 ft). This instrument is ideally suited for surface water and shallow groundwater applications, where precise water level measurements are essential. <\/li>\n<li>If, however, the anticipated water level fluctuation will be greater than the designed range, then the next available range should be chosen for that application.<\/li>\n<li>Example: 10 metres (30 feet) water level fluctuation is expected. To protect from possible over-ranging, the next available pressure range instrument (Levelogger 5 M20) should be selected. <\/li>\n<\/ul>\n<p>&#8221; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; parentOrderClass=&#8221;dsm_faq_0&#8243;][\/dsm_faq_child][dsm_faq_child dsm_title=&#8221;How do I know that I&#039;m using the most current version of software and firmware?&#8221; dsm_content=&#8221;<\/p>\n<ul>\n<li>The most current Levelogger software and firmware versions are available on the Solinst website<span> <\/span><a href=%22https:\/\/downloads.solinst.com\/solinst-software-firmware-downloads\/bf666c8da49%22 data-et-target-link=%22_blank%22 title=%22Solinst Downloads Page%22 data-uw-rm-brl=%22PR%22 data-uw-original-href=%22https:\/\/downloads.solinst.com\/solinst-software-firmware-downloads\/bf666c8da49%22 aria-label=%22Downloads - open in a new tab%22 data-uw-rm-ext-link=%22%22 uw-rm-external-link-id=%22https:\/\/downloads.solinst.com\/solinst-software-firmware-downloads\/bf666c8da49$downloads%22 rel=%22noopener%22>Downloads<\/a><span> <\/span>page.

Leveloggers are available in a number of different pressure ranges, which can be used for shallow piezometers to deep pumping well monitoring. The Solinst Levelogger software package includes features that allow you to incorporate manual water level field measurements; conduct barometric compensations; or adjust the data relative to another reference point (depth to water, ground surface elevation, etc.).  <\/li>\n<li>Remote monitoring via telemetry is also an option.<\/li>\n<\/ul>\n<p>&#8221; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; parentOrderClass=&#8221;dsm_faq_1&#8243;][\/dsm_faq_child][dsm_faq_child dsm_title=&#8221;Can the Levelogger be used in pumping tests?&#8221; dsm_content=&#8221;<\/p>\n<ul>\n<li>Yes, Leveloggers are excellent to use during all pumping tests. The Levelogger 5 and Levelogger 5 LTC can be programmed with a customised sampling schedule that sets the rates at which water level data is collected for a number of separate intervals. You can customise different sampling rates and durations to record water level readings before, during and after the pumping test (baseline, pumping and recovery). If deployed on a direct read cable, real-time Levelogger readings can be viewed and saved on a laptop computer or smart device during the pumping test.   <\/li>\n<li>See Technical Bulletin:<span> <\/span><a href=%22https:\/\/www.solinst.com\/products\/dataloggers-and-telemetry\/3001-levelogger-series\/technical-bulletins\/simplify-your-pumping-test.php%22 data-uw-rm-brl=%22PR%22 data-uw-original-href=%22\/products\/dataloggers-and-telemetry\/3001-levelogger-series\/technical-bulletins\/simplify-your-pumping-test.php%22>Simplify Your Pumping Test&#8230;Use a Water Level Datalogger<\/a><\/li>\n<\/ul>\n<p>&#8221; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; parentOrderClass=&#8221;dsm_faq_1&#8243;][\/dsm_faq_child][dsm_faq_child dsm_title=&#8221;Can I place a Levelogger beside an electric downhole pump?&#8221; dsm_content=&#8221;<\/p>\n<ul>\n<li>Yes, due to the Faraday cage design, all of the data recorded internally by the Levelogger will be unaffected by nearby electrical noise. Ideally, however, when deploying a Levelogger in a well with a pump, the Levelogger should be placed beyond any potential interference\/turbulence effects from the pump&apos;s intake. If a Direct Read Cable is used, a separate insertion pipe, that is earthed, is also recommended to prevent potential electrical interference with communication when collecting or viewing data running in Real-Time mode.

The Levelogger software includes a Data Wizard, which guides the user through the automated process of barometric compensation of their data. <\/li>\n<li>See Technical Bulletin:<span> <\/span><a href=%22https:\/\/www.solinst.com\/onthelevel-news\/water-level-monitoring\/water-level-datalogging\/barometric-compensation-and-the-importance-of-barometric-data\/%22 title=%22Barometric Compensation: The Importance of Barometric Data%22 data-uw-rm-brl=%22PR%22 data-uw-original-href=%22\/onthelevel-news\/water-level-monitoring\/water-level-datalogging\/barometric-compensation-and-the-importance-of-barometric-data\/%22>Barometric Compensation and the Importance of Barometric Data<\/a><\/li>\n<\/ul>\n<p>&#8221; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; parentOrderClass=&#8221;dsm_faq_3&#8243;][\/dsm_faq_child][dsm_faq_child dsm_title=&#8221;What if I do not have a Barologger?

The Levelogger software allows the user to enter manual water level measurements to field zero the data with known values. This practice helps to ensure the accuracy of the data and also allows the user to change the datum reference point for the data set.  <\/li>\n<li>If the reference datum or measuring point (e.g. top of well casing) is above water level, the field zero (measure depth to water) must be input as a positive value. If the reference datum is below water level (e.g. artesian condition), a negative value is input. The date and time of measurement of the reference datum must be recorded and input to complete the adjustment.  <\/li>\n<\/ul>\n<p>&#8221; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; parentOrderClass=&#8221;dsm_faq_3&#8243;][\/dsm_faq_child][\/dsm_faq][et_pb_button button_url=&#8221;https:\/\/www.solinst.com\/products\/dataloggers-and-telemetry\/3001-levelogger-series\/get-quote.php&#8221; button_text=&#8221;Get Quote&#8221; admin_label=&#8221;3001 get quote&#8221; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;c9e00792-1360-4998-8cf9-5f6772c944ba&#8221; custom_margin=&#8221;20px||||false|false&#8221; custom_padding=&#8221;6px|47px|6px|47px|false|false&#8221; global_module=&#8221;62109&#8243; saved_tabs=&#8221;all&#8221; global_colors_info=&#8221;{}&#8221;][\/et_pb_button][\/et_pb_column_inner][\/et_pb_row_inner][et_pb_row_inner _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;3676f7e6-7b83-4698-94ce-2cc9fa9ae43d&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_column_inner saved_specialty_column_type=&#8221;3_4&#8243; _builder_version=&#8221;4.27.2&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_text admin_label=&#8221;research article&#8221; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; hover_enabled=&#8221;0&#8243; global_colors_info=&#8221;{}&#8221; sticky_enabled=&#8221;0&#8243;]<\/p>\n<h2><strong>Levelogger Maintenance and Proper Use<\/strong><\/h2>\n<ul>\n<li>See Technical Bulletin:<span> <\/span><a href=\"https:\/\/www.solinst.com\/onthelevel-news\/water-level-monitoring\/water-level-datalogging\/ensuring-proper-use-and-levelogger-maintenance\/\" title=\"Ensuring Proper Use and Maintenance of Solinst Leveloggers\" data-uw-rm-brl=\"PR\" data-uw-original-href=\"\/onthelevel-news\/water-level-monitoring\/water-level-datalogging\/ensuring-proper-use-and-levelogger-maintenance\/\">Ensuring Proper Use and Maintenance of Leveloggers<\/a><\/li>\n<\/ul>\n<p>[\/et_pb_text][dsm_faq dsm_make_accordion_toggle=&#8221;on&#8221; dsm_animate_icon=&#8221;on&#8221; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;77be2b9f-999b-455f-afb8-d94da1ded8dc&#8221; hover_enabled=&#8221;0&#8243; global_colors_info=&#8221;{}&#8221; sticky_enabled=&#8221;0&#8243;][dsm_faq_child dsm_title=&#8221;What if I submerge my Levelogger deeper than the specified range?&#8221; dsm_content=&#8221;<\/p>\n<ul>\n<li>The Levelogger 5, Levelogger 5 Junior and Levelogger 5 LTC can withstand over-pressurisation of 2 times the specified range, e.g. a Model M10 can accommodate a fluctuation of 20 metres or 60 feet and still record pressure without damage.

To avoid icing\/ freezing and transducer damage, the easiest method is to lower the transducer to a point in the water column below the frost line or ice formation depth. <\/li>\n<li>In water bodies such as shallow streams, wetlands or ponds where icing\/freezing may penetrate to the bottom, install the Levelogger in a vented stilling well embedded into the bottom of the water body beyond the frost line.<\/li>\n<li>If this is not possible, place the Levelogger inside two elongated silicon, rubber or latex balloons filled with a non-toxic, non-corrosive anti-freeze solution or saltwater solution. Place the balloons in a section of perforated, 30 mm (1.25%22) ID pipe and install the logger in the monitored water. The anti-freeze solution will protect the Levelogger from ice expansion at the pressure transducer, yet transmit any pressure and temperature fluctuations that occur.  <\/li>\n<li>Note: Although precautions can be taken, placing a Levelogger in a situation where the water may freeze solid can permanently damage the sensor.<\/li>\n<\/ul>\n<p>&#8221; _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; parentOrderClass=&#8221;dsm_faq_4&#8243;][\/dsm_faq_child][dsm_faq_child dsm_title=&#8221;How can I protect my Levelogger from corrosive or marine environments?&#8221; dsm_content=&#8221;<\/p>\n<ul>\n<li>The Levelogger 5 and Levelogger 5 LTC have a corrosion-resistant coating that is baked-on using polymerisation technology (inside and out). In harsher chemical environments, you can protect the Levelogger using a balloon filled with non-corrosive\/non-toxic fluid (tap water).
