Fluid Components International Model MT91 flowmeter

Environmental, quality and plant managers responsible for reporting gas emissions from stacks and chimneys per European CEN or MCERT directives will find that the rugged MT91 multi-point gas mass flowmeter from Fluid Components International (FCI) offers an approved solution.

In accordance with the latest CEN and MCERTS guidelines, FCI’s Model MT91 flowmeter has been tested by TÜV and found to comply to EN 15267-1: 2009, EN 15267-2: 2009, EN 15267-3: 2007 and EN 14181: 2004.

The MT91 is specifically designed for gas flow measurement in large diameter pipes, stacks and ducts. It is a multi-point system capable of averaging up to 16 sensing points placed strategically across a stack’s cross-sectional area. Incorporating FCI’s precision no-moving parts thermal dispersion sensor technology, it delivers direct mass flow gas measurement with virtually no maintenance over many years of service. 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.

The 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 MT series has a smart flow transmitter with a powerful microprocessor-driven design for quality signal processing and data collection. This design includes a user-friendly menu-driven interface with a large LCD and keypad for programming the control, monitoring, display and driver/alarm functions. A non-volatile EEPROM chip stores applications and calibration data, and protects this data in the event of a power disturbance. Furthermore, the MT91 runs daily operation and integrity checks and reports its findings to the plant operator to ensure continuous proper operation.

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 easy user interface with DCS, PLC, SCADA, controllers or other recording devices.
