Envco – Environmental Equipment

FEATURES:
Non-Contact Measurement
Rugged and Fully Encapsulated
4-20 ma Transmitter
Easy Installation/No Programming
Cost Effective
Great for Wastewater
Great for Flumes and Weirs
Temperature Compensated
Three Ranges: 1ft, 3ft, and 6ft
For Monitoring Water Level and Open Channel Flow

There are three ranges available including 1ft, 3ft and 6ft to meet a wide variety of applications. The unique 1ft range sensor is ideal for measuring flow in small flumes and weirs. The 3ft and 6ftranges 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 20ft cable and complete instructions.

It is easy to interface to all PLCs, SCADA and telemetry systems with its simple 3-wire 4-20 MA output. The WL700 Ultrasonic Water Level Sensor is compatible and provided optionally with the Global Water FC200 Open Channel Flow Monitor and the PC300 Process Controller (for water level control).
