Ultrasonic Level Transmitters Product Description
The WL750 Ultrasonic Level Transmitters are perfect for short range, non-contact tank level measurements for a variety of liquids and solids.  The Ultrasonic Level Transmitters feature an integrated LCD display and transmitter unit that provides a local level readout as well as the ability to send a signal to another device.  The Ultrasonic Level Transmitters offer user-programmable settings and, in addition to the displayed values, feature an LED alarm light.

With the Ultrasonic Level Transmitter's narrow 8 degree beam angle and slim 1.38 inches (35mm) chemical resistant process end, the WL750 is designed for accurate level measurement -- even in relatively small tanks.  A 3-bolt 2 inch flange is included with each Ultrasonic Level Transmitter for secure mounting.  The WL750 Ultrasonic Level Transmitter's power and signal cable assembly is connected to the display unit with a molded on, locking 5-pin plug.  Choose from 16 ft (5m) or 33 ft (10m) cable assemblies, or purchase just the 5-pin plug alone to create longer cable runs.*

*NOTE: A cable assembly or 5-pin plug is required for the ultrasonic level transmitter.
