The WL700 uses the latest ultrasonic distance measuring technology for accurate non-contact water level monitoring. The fully encapsulated sensor/transmitter is temperature compensated and provides an industry standard 4-20 MA output. There are three ranges available including 1’, 3’ and 6’ to meet a wide variety of applications. The unique 1’ range sensor is ideal for measuring flow in small flumes and weirs. The 3’ and 6’ ranges are best for measuring river, lake and tank levels and for measuring open channel flow in larger flumes. Installation is simple and requires no programming or calibration. No maintenance is required.

The WL700 Ultrasonic Level Sensor is rugged, reliable and completely weatherproof. It is ideal for sewer or wastewater applications. The sensor is easy to mount, comes with a 20’ cable and complete instructions. It is easy to interface to all PLC’s, SCADA and telemetry systems with its simple 3-wire 4-20 MA output. The WL700 is compatible and provided optionally with the Global Water FC220 Open Channel Flow Monitor and the PC300 Process Controller (for water level control).
