The Aalborg Instruments GFM 473 is a thermal mass flow meter featuring an aluminum sensor measuring body and a medium temperature range from 0°C to +50°C. It operates at a maximum operating pressure of 69 bar overpressure and requires a power supply of 12 to 26 VDC at 200 mA. The unit delivers a measurement range ratio of 1:50, with standard conditions set at 20°C and 1 bar abs. It achieves an accuracy of +/- 1% of the end value and a repeatability of +/- 0.25% of the final value, with a 2-second response time at 25% to 100%. Wetted parts in contact with media comprise aluminum, brass, stainless steel (316 SS), and Viton O-rings. Process connections utilize 2 x 3/8" cutting ring screw connections for approximately 9.5 mm pipe. It provides linear output signals of 4-20 mA and 0-5 VDC, and includes pressure and temperature compensation.
