Thermal mass gas flow meter with a semi-circle clamp that fits with just two 4.5 mm drills — no pipe modification — ideal for machine-wise consumption metering.
KalkiVayu Thermal Mass Gas Flow Meters measure density and velocity separately for very high accuracy down to the smallest consumption — from 0.5 SCFM, fine enough to see individual machine leakage. The semi-circle mounting installs with two simple 4.5 mm drills and no pipe modification.
Semi-circle clamp mounts on pipes from 8 mm up to 2″ as standard — and up to 20″ clamps on request — without cutting or modifying the pipeline.
Best suited to individual machine consumption: up to 4 inputs record run-time and idle-time usage separately, with pressure and dew point sensors as optional inputs.
