The HS-40V Gas Purge Compressor has been designed to replace conventional nitrogen gas bottle supply to bubble units/gas purge systems for measuring water level in dams, rivers, canals and tanks with up to 30 mH2O (100 ft).

The HS-40V/3100 & HS-40V/3100A, with the inbuilt WL3100 pressure transducer, allows the measurement of water to an accuracy of 0.02% F.S.

The HS-40V differs from other bubbler systems, with its ability to purge any moisture in the mist separator out to atmosphere at the end of each pumping
cycle. Hence, minimal maintenance is required, longer operational life and higher accuracy in measurement.
