The Wireless Hydrostatic Level Transmitter is designed to accurately measure liquid levels by monitoring the pressure at the bottom of vented top-mount tanks, deep wells, water towers, rivers, and lakes.

The field-proven wireless transmitter seamlessly communicates with an assigned wireless gateway within the OTC Wireless Sensor and I/O Network, forming a highly scalable system that can accommodate virtually any I/O requirement. The Wireless Transmitter is certified for use in Class I, Division 1 (Zone 0) hazardous locations. It is intrinsically safe, designed not to cause a spark, and can be serviced without being removed from a process.
