LIQUID TANK LEVEL GAUGE SERIES: LTLG600 & HIGH ACCURACY (+/- 2.0 MM) & IDEAL FOR HUGE TANKS & RELIABLE OPERATION DESCRIPTION Indumart LTLG600 series of liquid tank level gauges are very reliable, robust and highly accurate instruments. They work based on measuring displacement by float. The float which is connected to the measuring tape rises and falls according to the change of liquid level inside the tank. When the float rises measuring tape is wound to the constant spring drum in proportion to the change in liquid level. When the float falls, measuring tape is released by the weight of float, and this movement of float is transmitted to the point-scale plate (or counter) by the gear mechanism. If remote indication is needed, the mechanical measurement is converted to a 4-20 mA output signal by a potentiometer.
