Ground Water level monitoring is gaining importance as we are learning to value our precious supply of fresh water. With only 3% of all water on the planet being non saline and with less than 40% of the same being available to us various agencies regularly monitor the availability and usage of this most precious resource.
Most often we tap into the reserves held by our soil in permeable layers, through borewells. This is only .8% of globally available water. Agriculture takes up 80% of the water we require. This makes it even more important that we conserve and judiciously use the same.
Ground water levels may be monitored with analog or electronic devices.
Electronic water level loggers
Automatic water level monitors (Levelogger) record highly accurate groundwater and surface water level and temperature measurements. It combines a pressure sensor, temperature detector, 10-year lithium battery, and datalogger, sealed within a 7/8″ x 6.25″ (22 mm x 159 mm) stainless steel housing with Titanium based PVD coating.
The Levelogger Junior Edge provides an inexpensive alternative for measuring groundwater and surface water levels and temperature. The Levelogger Junior Edge combines a pressure sensor, temperature detector, a datalogger, and 5-year battery (based on a 1-minute sampling rate) in one compact 7/8″ x 5.6″ (22 mm x 142 mm) stainless steel housing.
The LTC Levelogger Junior logs conductivity, as well as water level and temperature. Like the LT Levelogger Junior Edge, it is easy to transport, program, deploy and retrieve data. It combines a datalogger, 5-year battery, Hastelloy pressure sensor, temperature detector, and conductivity sensor within a small waterproof housing, 7/8″ x 7.5″ (22 mm x 190 mm).
For measuring the depth to water in wells, boreholes, standpipes, and tanks, Model 101 Water Level Meters are the industry standard for portable hand operated meters. They are sturdy, easy to use and read accurately to 1/100 ft. or each millimeter. When contact is made with water, the circuit is completed, activating a loud buzzer and a light. The water level is then determined by taking a reading directly from the tape at the top of the well casing or borehole.
