Description PL301 Submersible level transmitter
PL301 hydrostatic level transmitter is specially designed for continuous monitoring of water well, reservoir, water tank, borehole and river level.
The submersible measures the static pressure of the liquid column above the transmitter and transmits a current signal proportional to the water column to the instrument above.
The highly stable 316L stainless steel diaphragm sensor is fully compatible with raw or chlorinated water and most semi-corrosive liquids.
A special ventilation cable is provided to compensate for changes in atmospheric pressure, which accurately transmits measured liquid level. The cable length associated with the application can be determined to the desired range at the time of purchase or can be adjusted by the customer at the application site.
The PL301 submersible level transmitter/hydrostatic level sensor is designed for use in rivers, reservoirs, water tanks, boreholes, ships and channels. Because of their long-term immersion protection up to 100 meters, they are also ideal for measuring pressure in underwater pipelines and vessels. For applications with corrosive media such as seawater or leachate, especially in landfills, we can offer advanced dual phase stainless steel submersible level transmitters with high corrosion resistance.
