The HLS Series Level Sensor from Hayward Flow Control is an accurate level sensor that is not affected by foaming, waves or headspace vapors. With a complete CPVC housing and construction, it is ideal for corrosive fluids and environments where metals cannot perform. It measures hydrostatic pressure and converts the reading to an analog 4-20mA signal, which can be displayed on a wide range of indicating transmitters or taken directly into a PLC. Its large ceramic diaphragm ensures accuracy and repeatability, while a triple-sealed cable entry into body and PFA-coated cable offers superior chemical compatibility. It has a 0 to 15 feet and 0 to 33 feet water measurement range, with 30- and 49-foot cable lengths standard, and other lengths available upon request. 888/429-4635; www.haywardflowcontrol.com; Booth 5349.
