The Model HS40AFC Compact is the small and lightweight version of the proven HS40 Series II gas purge compressor constant bubble system. It has been designed to replace a conventional dry nitrogen gas bottle supply to a bubble unit. The HS40 Compact is used for measuring water level in dams, rivers, canals and tanks with up to 40 mH2O (130 ft) head. It provides very accurate and reliable measurements.
The system consists of air compressor, pressure tank, membrane filter dryer, micro mist separator with an auto purge valve and bubbling system. All components are housed in a single small enclosure. Built-in smart pump control monitors the pressure in the system to optimize power consumption while ensuring best operation and accuracy. The HS40 Compact is a fully self-contained and user-friendly system that requires no regular maintenance and no special software.
The HS40AFC can be fitted with the tried and proven pressure sensor WL3100 or WL3100A (accuracy +/-0.02 % FS) with full temperature compensation.
The HS40 Compact is available either as a complete unit with in-built KISTERS’ pressure sensor of choice or as a stand-alone system for deployment with the user’s own pressure sensor.
