OMEGA FMA1605AI Gas Flow Meter

The FMA-1600A series mass and volumetric flow meters by Omega utilize differential pressure within a laminar flow element to accurately measure gas flow rates. The device features a laminar flow element (LFE) that ensures a streamlined flow of the gas, allowing the Poiseuille equation to relate pressure drop to volumetric flow rate. Built-in temperature and pressure sensors adjust the readings to standard conditions. These flow meters support a maximum flow rate of 2 SLM, with 4 to 20mA output and RS232 communication capabilities. They connect via a 1/8 FNPT fitting and include 130+ gas calibration options for pure and mixed gases. Designed for ease of use, they require no warm-up time, no straight pipe runs, high turndown ratio of 200:1, and come with comprehensive accessories including power supply, operator manual, and NIST certificate.
