Dwyer GFM-CBL4 Gas Mass Flow Meter accurately measures gas flow in clean environments. It operates in a temperature range of 32 to 122°F (0 to 50°C) with an accuracy of ±1% FS. The response time is 2 seconds, and it has a voltage of ±12 VDC. The output options are linear 0-5 VDC and 4-20 mA. The meter is compatible with clean gases and has a 90° tiltable display. Wetted materials include anodized aluminum, brass, and 316 SS. Max pressure limit is 1000 psig (68.9 bar) and the process connection sizes vary from 1/4" to 3/4". Repeatability is ±0.25% of FS and it has excellent leak integrity.
