Liquid Level Transmitter - Magnetostrictive

OleumTech Wireless Liquid Level Transmitter is a self-contained, battery-powered tank level gauge that provides a 3-in-1 continuous liquid level monitoring solution of product level, interface level and temperature level. This liquid level sensor utilizes field-proven magnetostrictive level sensor technology with high resolution of 0.01-inch and is ideal for tank level and liquid level monitoring. The wireless liquid level sensor can be ordered in various lengths with a Rigid 316 stainless steel or Ultra-flex sensor with standard or large size floats (stainless steel or plastic). This device is part of the OleumTech Wireless Sensor Network.

This wireless tank level sensor is a cost-effective spill prevention and inventory monitoring solution for the oil and gas, water and wastewater, and agricultural industries and for many other industrial applications when monitoring liquid level is most critical.

This OleumTech wireless liquid level sensor is intrinsically safe certified for use in Class I Division 1 (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 liquid level data to a Wireless Gateway that supports Modbus.
