About HPT604 Level Sensor

HPT604 is a submersible level sensor transducer suitable for liquid level or pressure and depth measurement. It made of 316 SS housing.

Its all stainless steel, suitable for immersion in most industrial liquids and oils.The welded housing is tested in-house via a helium leak tester to ensure proper protection. 

Ventilation tube in the cable automatically compensates for changes in atmospheric pressure above the tank. 

The HPT604 Submersible Liquid Level Transmitter can be used to measure water level; well depth; groundwater level; bore well, underground water, river etc,.
