The Dwyer Instruments GFM-1143 Gas Mass Flow Meter is a high-accuracy flow measurement instrument engineered for monitoring clean, dry gases with exceptional repeatability. Featuring a flow range of 0–200 LPM, this model is factory-calibrated for nitrogen at 70°F (21°C) and 760 mm Hg, and includes a 3/8″ compression fitting for secure and reliable connections.

Equipped with a straight tube sensor and restrictor flow element, the GFM-1143 provides flow readings that are virtually unaffected by changes in temperature and pressure. Its 3½-digit tiltable LCD display allows real-time flow monitoring in standard engineering units. The meter offers both analog voltage (0–5 VDC) and current (4–20 mA) outputs, making it suitable for integration with data acquisition systems or controllers.

With an accuracy of ±1% of full scale, repeatability of ±0.25% FS, and fast 2-second response time, this flow meter delivers stable and consistent results ideal for laboratory research, process control, and OEM integration.

Every Dwyer GFM-1143 unit comes with a NIST-traceable calibration certificate, ensuring measurement reliability and traceability to international standards. Constructed from anodized aluminum, brass, and 316 stainless steel with fluoroelastomer seals, it is compatible with a wide range of clean gases.
