Water Level Meter WM-20M 20 Meters

Features and Benefits - Flexible tape/cable for easy winding and unwinding, even in cold temperatures - Waterproof design - Permanent depth markings with extra tubing protection - Strong 80lb base magnet allows it be placed at any angle of metal section of borehole, well or standpipe etc. - 3 bright LED signals, that can be view at any angle even in bright sunlight up to 40 ft - (2) 9 volt batteries power the tool providing maximum usage between battery changes - Lightweight pocket size and portable - Ergonomically designed for ease of use - Probe can quickly and easily be attached to magnetic base while not in use or can hang from handle prior to use- Magnetic base allows it to be fastened on metal panel of work van or any metal surface for quick and easy access -- On/ Off switch conserves battery life - Power drill nut driver attachment can be used to speed up the winding and unwinding of tape/cable and prevent fatigue.
Operation The Water Level Meter can be used at any angle and can be easily attached to any well, borehole, standpipe etc. that has a metal surface. Each Water Level Meter is comprised of a metal probe fitted to a flexible cable wire tape that is wound on to a hand-held reel with an ergonomically handle. The cable is connected to an electronic circuit, 3 LED (light) signal indicator and (2) 9-volt batteries and an On / Off switch. The sensor probe incorporates an insulated gap which acts as a switch, the circuit being completed when contact is made with the water. The cable consists of a non-stretch flexible wire/tape with copper conductors marked in 4” intervals or 10cm intervals depending on unit. For more accurate measurements the ruler on unit can be used or the provide metal ruler. The probe is lowered down the borehole, standpipe, well, etc. Caution: keep cable wire away from any sharp edges. You can lower the probe by hand unwinding or with drill attachment. When it makes contact with water, the 3 LED’s come on. A reading can then be taken from the measuring cable at the port level to record the depth. Ensure the unit is turned off after to conserve battery life. Measuring the depth to the closest ½” - Use the cap‘s ½” notched lines as a guide by placing the wire along rubber sides and counting notches Example: 2 notches equal 1” & 6 notch’s equal 3” Also, the distance between LED’s along rubber sides is 4” (8 notches). Use the ruler markings on the magnetic base or ruler provided for more accuracy once the closest footage distance is noted. - Place wire along the ruler, aligning the closest ft marker of the water depth to the zero point of ruler then add the distances from there. See Image to the right. Winding of the water level meter cable can be done manually by hand or with drill.
