Description
Model WLV7389-24-SB Wireless Ultrasonic Tank Level Transmitter provides a license free 2.4GHz wireless
bridge between level sensor and process instrument at a distance up to 1 mile line-of-site (LOS).
The sensor/wireless transmitter combination
accomplishes tank level measurement by providing a 4-20mA current or 1-5V DC voltage output
on the wireless receiver side that corresponds to distance measured by the sensor. Connect the receiver
output to a process meter or PLC to control a pump, valve or alarm unit.
