FLOWTECH Conductivity Type Level Switches are intended for level detection of Tank Level Control and Pump & Process Protection in Electrically Conductive Liquids such as Water, Beverages, Lye Solutions, Acids, and Graphite etc. These are available in Top Mounting OR External Cage Top Mounting versions. These are Cost effective & having Reliable Performance, Easy installation, Ideal for simple applications, No moving parts hence long term reliability.

WORKING PRINCIPLE

Conductive Electrodes detects the level when the Electrodes are coming into contact with the Liquid. A low adjustable resistance, alternative current flows between the grounds (Earth) and the Electrode. This current is detected by signal conditioning instrument and processed into a switching signal. The switch point is determined by the length and mounting position of the appropriate electrode. In conductive Tank / Vessels, the Tank / Vessel wall forms the ground electrode and incase of a plastic OR FRP OR Rubber Lined (NON CONDUCTIVE) Tank / Vessel, the conductive electrode consists of one of the probes.
