  • User adjustable limits & alarm points
  • Scaleable 4-20mA signal output










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.

WL700 Ultrasonic Water Level Sensor  
WL400 Water Level Sensor
When ordering, specify water level range that will cover the maximum water level change for your application (this is not necessarily the total depth of water): 0-3', 0-15', 0-30', 0-60', 0-120', 0-250', 0-500'.  Selecting the smallest water level range possible will ensure the greatest accuracy.  Includes 25 feet of cable.
PC300 Process Controller
Process control meter and industrial control system.
WL16 Water Level Logger
Submersible pressure transducer and datalogger for recording water level data.
