WH311 series liquid level transmitter are designed to meet the rigorous environments of applications such as deep well monitoring, pump tests,lift stations, chemical tank levels,groundwater and surface water measurement, and process control. Providing a 4-20mA output signal compatible with DCS,PLC s, panel meters, data loggers, and other electronic equipment.This is ideal for solar or battery powered installations. These transmitters can offer all ranges equivalent from 1 psi through 300psi while all units of measure and cable lengths are customer-defined for individualized specifications.
The WHsensors WH311Series Submersible Level Transmitters are manufactured for years of trouble free service. The pressure transmitter measures the height of liquid above the position in the tank referenced to atmospheric pressure. Lightning and surge protection (not guaranteed or covered by standard warranty) is included standard to stand up in harsh applications. The transmitters are vented for barometric pressure compensation. Vent is covered with a maintenance‐free filter preventing particulate or water droplets from entering the transmitter. We offer the WH311 desiccant filter that can be attached to the vent tube.
