Submersible Level Transmitters: Everything You Need to Know

When measuring levels of water, submersible transmitters are effective instruments that can measure the level and depths of liquid in different water applications such as ground water and wastewater. Submersibles are trusted to be used in municipalities and many water applications because of the efficiency to measure levels for a variety of reasons. In this blog article, we provide the details on the type of technology and construction that is crucial for PMC-STS' submersible level transmitters.

Piezoresistive Sensor Technology for Accurate Level Measurements

A submersible transmitter measures level by receiving a measurement of hydrostatic pressure of a liquid first. PMC-STS' submersible transmitters measure hydrostatic pressure through a piezoresistive sensing diaphragm. Then, the submersibles utilize a transducer to convert hydrostatic pressure into a signal of electricity. When the sensor senses a change in pressure, its electrical resistance changes as well. The electrical signals are converted to signal outputs of 4-20mA.

Measure Level Effectively With Durable Transmitter Construction

Submersible level sensors are designed for water applications which means they would have to be able to withstand water damage. PMC-STS' VL2000 Wastewater Level Transmitter stands strong with the test of time in pumps and lift stations for wastewater applications for an average of 10+ years.

How does this submersible transmitter hold up strong? The VL2000 avoids clogging and sludge build up encountered in wastewater applications through its rugged flush open-face design. The transmitter consists of a ceramic sensing element and can be made of either stainless steel constructions that can be used for most applications or titanium that can be utilized for chemical environments. Along with this, a polyurethane vented cable is molded so the transmitter is waterproof.

 

Conclusion

Submersible level transmitters utilize advanced technology to measure the levels of water applications. With strong manufacturing and design along with high accuracy, submersible transmitters can stand the test of time while providing users accurate level measurements.
