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 STS submersible level transmitters.
A submersible transmitter measures level by receiving a measurement of hydrostatic pressure of a liquid first. Submersible transmitters from STS Sensors 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.
Submersible level sensors are designed for water applications which means they would have to be able to withstand water damage. The VL2000 Wastewater Level Transmitter from STS stands strong with the test of time in pumps and lift stations for wastewater applications for an average of 10+ years.
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 stainless steel or titanium constructions depending on the application needs. Along with this, a polyurethane vented cable is molded so the transmitter prevents water ingress.
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.2
