Ultrasonic Water Level Sensor Product Description
|
|
The WL705 Ultrasonic Water Level Sensor uses the latest ultrasonic distance
measuring technology for accurate non-contact water level monitoring. The
ultrasonic water level sensors contain a rugged transducer in a stainless steel
sealed housing for long life and provides an industry standard 4-20 mA
output. There are three ultrasonic water level sensor ranges available
including 3 ft, 12 ft, and 48 ft to meet a wide variety of applications.
The unique 3 ft range ultrasonic water level sensor is ideal for measuring flow
in small flumes and weirs. The 12 ft and 48 ft ultrasonic water level
sensor ranges are best for measuring river, lake and tank levels and for
measuring open channel flow in larger flumes. Ultrasonic water level
sensor installation is simple and requires no programming or calibration.
No maintenance is required for the ultrasonic water level sensors.
The WL705 Ultrasonic Level Sensors are rugged, reliable and completely
weatherproof. The ultrasonic water level sensors are ideal for sewer or
wastewater applications. The ultrasonic water level sensors are easy to
mount, come with a 6 ft standard cable and complete instructions. The
ultrasonic water level sensors are easy to interface to all PLC's, SCADA and
telemetry systems with its simple 3-wire 4-20 mA output. The WL705
Ultrasonic Water Level Sensor is compatible and provided optionally with the
Global Water FC220 Open Channel
Flow Monitor and the PC320
Process Controller (for water level control).
