Designed to provide 4-20 mA output. They are field modifiable and programmable to meet application requirements. Web based software for programming specific configuration. Compact design minimizes shipping costs.
Typical applications include vertical vessels, pilot receivers and pump accumulators. The WLT probes are direct replacement for LP and VLT probes and the WLT-C probes are replacements for probes/controllers with valve control functions.
