It is mounted on a small handheld spool and stand to conveniently extract or withdraw the cable and electrode assembly.ĭepth indicated by numbered metal tags securely crimped to the cable at intervals of five feet or every meter on the metric model WLTM. This information is available in different formats such. The meter comprises a stainless steel probe fitted to a. Using a rating relationship between depth and discharge, flow can be estimated from depth readings on streams. Water Level Meters are used to measure the depth of water in standpipes, wells and boreholes. The cable is two-conductor, steel and copper plated, with a tensile strength of approximately 300 pounds and a tough plastic insulating jacket. The District has 217 water-level gages on streams, channels, basins and dams throughout the Maricopa County region, measuring water depth and transmitting that data in real time. The WLT is available with a 1/2” diameter brass on a special-order basis. The brass electrode assembly is 3/8” in diameter and can be replaced in the field. You might need to make your string longer if you underestimated your well depth. The total length of the assembled meter, tip to tip including the sensor and eye bolt, is. Lower the string into the well until you hear and feel the weight landing in the water. 1.Assemble the meter case as shown in Figures 1 and 2 above. They have zero-position memory, also known as absolute (ABS) positioning, which retains the measuring position when the gauge is turned off. All are IP67 rated for protection from dust and temporary water submersion. Tie a weight or fishing float to one end of the string. These gauges come with a calibration certificate traceable to NIST that states theyve passed a test for accuracy. Available site descriptive information includes well location information such as latitude and longitude, well depth, and aquifer. To get the most accurate depth-to-water measurement of a deep well, swap the tape measuring tool for a long piece of string. Contact of the electrode assembly with the water surface is indicated by an LED and an audio alert. The Groundwater database consists of more than 850,000 records of wells, springs, test holes, tunnels,drains, and excavations in the United States. The example in the instructions used inches so I used imperial 48 inches and input the percentage then synced the sensor unit to the WiFi unit. The WLT Water Level Indicator provides an economical and reliable means of obtaining accurate water level data in water wells. The calibration is your percentage estimation of the tank water depth in relation to the tank capacity based on either metric or imperial.
