The Aalborg GFM 573 is a thermal mass flow meter designed for accurate gas measurement, with available measurement ranges from 0-100 l/min to 0-200 l/min, based on nitrogen at 20°C and 1 bar absolute. This system is working pressure and temperature-compensated. It features an aluminum sensor measuring body and wetted parts consisting of aluminum, brass, stainless steel (316 SS), and Viton O-rings. The unit operates within a medium temperature range of 0°C to +50°C and handles a maximum operating pressure of 34.5 bar overpressure. It operates on a power supply of 12 - 26 VDC (200 mA) and provides linear output signals of 4-20 mA and 0-5 VDC. The process connection utilizes 2 x 3/8" cutting ring screw connections for approximately 9.5 mm hose or pipe. It delivers a measurement range ratio of 1:50, a response time of 2 seconds at 25% to 100%, a repeatability of +/- 0.25% of the final value, and an accuracy of +/- 1.5% at 15°C to 25°C and 0.35 bar to 4.1 bar abs (otherwise +/- 3%).
