Paddle Wheel Flow Meter

Paddle Wheel Flow Meter

Capacitance level transmitter is used in level sensing applications of variety of Liquids. It’s available for non conductive as well as conductive liquids. It is offered with PTFE sleeve for better insulation & to withstand high temperature. In conductive tanks the insulated probe acts as one electrode & the tank wall as another lectrode, any change in liquid level the dielectric value will change thereby changing the capacitance value proportional to the liquid level. In case of non conductive media applications / non conductive tanks, a reference probe is provided as ground electrode. The output is 4-20mA, 4 wire connection for Isolated supply & 3 wire for non isolated supply. The tank empty ( 4mA) & full (20mA) calibration is through easy field calibration button in case of 4 wire & 3 wire. Rigid probe is offered for tank depth upto 3 mtr & Flexible probe upto 30 mtr. Rigid Probe with Grounding tube is suitable for Fuel Level measurement. It is available with different mounting arrangement to suit customer requirement.
