British OEM Thermal Gas Mass Flowmeter
Chell's CMF flowmeter has ranges from 0-10 cm3/min to 0-100 litre/min and first deliveries have an overall specification of +/-3% Full Scale, including temperature coefficients for ambient and gas temperatures from 15- 60degC.
Thermal gas mass flowmeters provide far more robust flow data than any displacement or hot wire-based flow transducers due to their greater intrinsic thermal stability. CMF errors are a fifth those of volumetric flowmeters such as rotameter variable area types.
