L6 – Ultrasonic

L6 – Ultrasonic

This liquid level sensor utilizes field-proven ultrasonic level sensor technology with high resolution of 1mm and is ideal for monitoring water storage tanks of up to 12 ft. It provides mounting hardware with 6-inch adjustable compression fitting.

Equipped with a local LCD display that can be used for reading process data and for programming the device. Thus, cables and PC are no longer required for quickly setting up the device.

Description

OleumTech WT Series Wireless Liquid Level Transmitter – Ultrasonic is a self-contained, battery-powered liquid measurement solution is non-contact and has no moving parts and is made especially for the remote, rugged environments without access to a power line.

This liquid level sensor utilizes field-proven ultrasonic level sensor technology with high resolution of 1mm and is ideal for monitoring water storage tanks of up to 12 ft. It provides mounting hardware with 6-inch adjustable compression fitting.

All WT Series Wireless Transmitters are equipped with a local LCD display that can be used for reading process data and for programming the device. Thus, cables and PC are no longer required for quickly setting up the device.

The Wireless Ultrasonic Liquid Level Transmitter is intrinsically safe (certified for use in Class I, Division 1 C1D1 Wireless (Zone 0) hazardous areas). It can be operated in a hazardous environment with or without the enclosure without the risk or fear of causing an explosion. This wireless end node transmits collected data to a Wireless Gateway that supports Modbus. The transmitter uses license-free, secure data transmission with a range of up to 7500 ft. Range (2.3 Km).
