Model WLV7389-900-SB Wireless Ultrasonic Tank Level Transmitter provides a license free 900 MHz wireless bridge between level sensor and process instrument at a distance up to 6-mile line-of-site (LOS). The sensor/wireless transmitter combination accomplishes tank level measurement by providing a 4-20 mA / 1-5V DC, or 0-5V DC output on the wireless receiver side that corresponds to distance measured by the sensor. Connect the receiver output to a process instrument or PLC to control a pump, valve or alarm unit.
