Endress+Hauser announces Waterpilot FMX21 Level Sensor for Wastewater

April 22, 2010 — Waterpilot FMX21 level sensor has a stainless steel housing and an easy-to-clean, flush-mounted process diaphragm, making it ideal for measuring the level of sludge and wastewater. With an optional Pt 100 sensor, it can also measure temperature. A corrosion-resistant, coated version is available for use in particularly aggressive environments, such as salt water. The FMX21 uses a ceramic cell to measure pressure. Any changes in pressure cause a change in capacitance, which the sensor’s electronics convert into a 4-20mA signal that is linear to the level of the liquid. HART 6.0 is superimposed on the 4-20mA signal, allowing an operator to adjust the range remotely. The sensor is ideal for sludge because the ceramic cell withstands corrosion better than any other material. Cleaning is very easy, without losing calibration, a characteristic of ceramic diaphragms. Applications include lift stations, thickeners, digesters and sludge holding tanks. For water and wastewater applications, it has KTW, NSW and ACS drinking water approvals. A wide range of accessories make it easy to implement complete measuring point solutions in a water plant. By using the Field Xpert PDA, operators can communicate to the FMX21 wirelessly, to set all parameters and diagnose problems.
