The GFM 373 is an Aalborg thermal mass flow meter designed for precise gas measurement applications. Featuring pressure and temperature compensation, this meter operates within a medium temperature range of 0°C to +50°C and handles a maximum operating pressure of 69 bar overpressure. It delivers an accuracy of +/- 1% of the end value of the measurement range and a repeatability of +/- 0.25% of the final value, with a rapid response time of 2 seconds at 25% to 100%. Built with an aluminum sensor measuring body and media-contacting parts including aluminum, brass, stainless steel (316 SS), and Viton O-rings, the GFM 373 utilizes 2 x 1/4" cutting ring screw connections for approx. 6.3 mm pipe. It requires a power supply of 12 - 26 VDC (200 mA) and provides linear output signals of 4.. 20 mA and 0.. 5 VDC. Measurement ranges are available from 0 - 15 l/min to 0 - 50 l/min, based on nitrogen at standard conditions of 20°C and 1 bar abs. Please specify the measurement range and gas type when ordering.
