FCI MT91 multipoint gas mass flowmeter

Click2Contact

The MT91 multipoint gas mass flowmeter from Fluid Components International (FCI) has been tested by TÜV Rheinland Germany and found to comply to EN 15267-1: 2009, EN 15267-2: 2009, EN 15267-3: 2007 and EN 14181: 2004.

The MT91 is designed for gas flow measurement in large diameter pipes, stacks and ducts. It is a multipoint system capable of averaging up to 16 sensing points placed strategically across a stack’s cross-sectional area. Incorporating FCI’s no-moving-parts thermal dispersion sensor technology, it is claimed to deliver direct mass flow gas measurement with virtually no maintenance over many years of service for a low life cycle cost. The MT91’s fully temperature-compensated flow sensor electronics are highly stable with almost no drift for accuracy and repeatability with configurations available for operation in high-temperature environments up to 454°C.

FCI’s MT91 flowmeters feature a wide turndown range available from 5:1 to 100:1 with flow sensitivity from 0.08 to 46 NMPS.

The sensor assembly is available with flanged, threaded and retractable process connections with an IP66-rated (NEMA/CSA Type 4X) junction box and installed at the desired location with a choice of process connections.

The flow element assembly is connected remotely by cable to the electronics package up to 304 m away. Dual 4-20 mA analog outputs of flow rate and temperature and dual DPDT relays are standard outputs for interfacing with DCS, PLC, SCADA, controllers or other recording devices.
