Dwyer GFM-2141 Gas Mass Flow Meter is a reliable and accurate device for measuring flow rates of clean gases. It operates at a temperature range of 32 to 122°F (0 to 50°C) and offers an accuracy of ±1% FS. With a response time of 2 seconds and a voltage of ±12 VDC, it provides a linear output of 0-5 VDC and 4-20 mA. The 90° tiltable, 3-1/2 digit display enhances usability, and the wetted materials ensure compatibility with various gases. It has a pressure limit of 1000 psig (68.9 bar) and a process connection ranging from 1/4" to 3/4". The GFM-2141 offers a particulate size tolerance of 5 microns, repeatability of ±0.25% of FS, and leak integrity of 1 x 10-9 sccs of Helium.
