Sapcon - Model MPLOH -Differential Level Transmitter for Water Treatment Plants

The capacitance formed by sensing probe and water is measured, and it is directly proportional to the level of water known as ‘Head’. By measuring heads at two points, namely ‘High Head’ and ‘Low Head’, their difference can be calculated. This difference is ‘Loss of Head’. LOH sensor measures the heads in millimeters and thus calibration might be required on site. The two sensors digitally send their level values of head heights in digital format over the same set of wires. A shielded cable should be used to assure flawless operation.
