SmartMeasurement’s ATMF8000 insertion mass flowmeters are thermal dispersion type, utilizing the constant temperature difference method of measuring Gas Mass Flow Rate. It contains two reference grade platinum RTD sensors clad in a protective 316 SS sheath. Features include direct mass flow for gases , wide rangeability, low pressure drop, excellent low-end sensitivity, and no moving parts. The SMC ATMF series is microprocessor based; it does not have any potentiometers. The electronics can be integral or remote mount with a rugged, windowed dual-compartment enclosure. Four models available ranging from the low cost blind meters to the full-featured SP models.

      Each flow meter has built in diagnostics - a display of the calibration milliwatts (mw) can be used to check the sensor’s operation by being compared to the original reported “zero flow” value noted on meter’s Certificate of Conformance metallic tag. This convenient field diagnostic procedure verifies that the original factory calibration hasn’t drifted, shifted, or changed. This “Sensor Functionality and Zero Self Check” also verifies that the sensor is free from contamination, even without inspection.
