Water Level Indicator
Water level employs a non-stretch cable in required lengths (say 10, 30, 45 and 90 meters), marked at every meter. This is supplied in a wooden carry case, fitted with carry handle/solder strap for field use. Cable ensures resistance against stretch and minimizes friction at walls. Cable is winded on sturdy aluminum reel and lowered by unwinding handle. 22/18/12 mm diameter stainless steel/brass probe ensure long life and very little water displacement. 2 (or 4) AA size standard dry batteries utilize high power only during the time, probe is in touch with water. Control panel has two LEDs, one blows at battery ‘ON’ and other ‘Water Level Contact. Buzzer turns ‘ON’ along-with water contact LED.
