The GFM-1143 model from Dwyer's Series GFM combines a straight tube sensor with a restrictor flow element, ensuring precise measurements unaffected by temperature and pressure variations. It features a 3-1/2 digit, 90° tiltable LCD readout that displays actual gas flow in engineering units. The device is compatible with the Series GFT Flow Totalizer for applications requiring totalization and includes a NIST traceable certificate, confirming its measurement accuracy.
