The Flowline® EchoPod® and EchoSonic® II lines of ultrasonic liquid level sensors and transmitters are constructed with PVDF transducers and NEMA Type-6P polycarbonate enclosures. These sensors replace float, conductance and pressure sensors that fail due to contact with dirty, sticky and scaling media in small, medium and large capacity tanks. These units are available with single- and multi-function capabilities, including continuous level measurement, switching and control. The line is easily configurable via the WebCal PC software and the available USB fob adapter. A variety of accessories is available, including mounting brackets, reducer bushings, bulkhead fitting and flanges.
