Air Monitoring Gas Flow Meter Receives TÜV Certification for QAL1 Compliance


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 Flow Meter from Fluid Components International (FCI) is now their approved solution.


In accordance with the latest CEN and MCERTS guidelines, FCI’s Model MT91 Flow Meter 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. TÜV, an internationally recognized body for approving emissions monitoring equipment, assures FCI’s customers with independent approval that the MT91 Mass Flow Meter meets its specifications, complies with these directives and is suitable for reporting per these directives.


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 sixteen (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 for an exceptionally low life-cycle cost. The MT91’s fully temperature-compensated flow sensor electronics are highly stable with almost no drift for excellent accuracy and repeatability with configurations available for operation in high temperature environments up to 454°C (850°F).


FCI’s highly versatile MT91 flow meters feature a wide turndown range available from 5:1 to 100:1 with flow sensitivity from 0,08 NMPS to 46 NMPS (0.25 SFPS to 150 SFPS). 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 popular process connections.


The MT series offers a smart flow transmitter with a powerful microprocessor-driven design for superior signal processing and data collection. This design includes a user-friendly menu-


driven interface with a large LCD display and keypad for programming the control, monitoring, display and driver/alarm functions. A nonvolatile 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 (1000 feet) away. Dual 4-20mA analog outputs of flow rate and temperature and dual DPDT relays are standard outputs for easy user interface with DCS, PLC, SCADA, con- trollers or other recording devices.

Thermal Mass Flow Meter Measures Greenhouse Gas


Magnetrol International (Belgium) announces that their Thermatel Model TA2 Thermal Mass Flow Meter measures greenhouse gases in accordance with the new US Environmental Protection Agency rule (EPA 40 CFR part 98). This new mandate requires companies emitting


more than 25.000 tons/year of CO2 equivalent to report greenhouse gas emissions effective January 1, 2010. The Magnetrol Model TA2’s thermal dispersion technology provides an accurate and economical method to measure the amount of emitted methane or natural gas,


and assesses emissions of carbon dioxide (CO2), meeting the EPA requirements.


Magnetrol’s TA2 is a direct mass flow measuring instrument and requires only a simple, single insertion point into a pipe or stack to install. The accuracy is better than ±1% of reading +0,5% of calibrated full scale and exceeds the stated acceptable accuracy within this new EPA rule. Instruments are available for installation in line sizes from 15 mm up to more than 3000mm. It operates over a wide flow range from 0,13 to 200 Nm/s with an exceptionally wide turndown ratio up to 100:1.


The flow sensing element of the Model TA2 is manufactured with all-welded construction and available in 316/316L or Hastelloy C. There is virtually no pressure drop when using a thermal mass flow meter and it has no moving parts and is, therefore, less sensitive for clogging and fouling. The instrument measures and displays mass flow rate, totalised flow and temperature with electronic output of passive and active 4- 20mA signal including HART®


protocol. Actual


gas calibration will be performed on each TA2, matched to the customer application and installation conditions.


There are several flow measurement technologies that can be used for the measurement of greenhouse gases. However, thermal dispersion mass flow meters provide certain advantages in terms of mass flow measurement, turndown, (low) flow sensitivity, low pressure drop, and ease in installation. In fact, the TA2 thermal mass flow meter will provide the lowest cost of ownership for facilities that are required to measure the greenhouse gas emissions from their processes to comply with this new EPA requirement.

Ecotech Announces EN Approval for the Serinus Gas Analyser Series


Ecotech, one of the world’s leading manufacturers of air quality monitoring equipment is pleased to announce EN approval for its Serinus gas analyser range. According to Ecotech’s General Manager, Nicholas Dal Sasso, “The approvals are a vital step in Ecotech’s expansion within Europe and provides the European community with a greater choice of ambient gas analysers”. Nicholas went on to say “We are confident that the Serinus will give our European customers the performance they need, with Ecotech’s proven reliability, along with enhanced data transfer and communication.”


The Serinus series includes the following: Model


Serinus 10 Serinus 30 Serinus 40 Serinus 50


39


Parameter Ozone (O3)


Carbon Monoxide (CO) Oxides of Nitrogen (NOX)


Sulfur Dioxide (SO2)


MCERTS certificate # Sira MC 100165/00 Sira MC 100166/00 Sira MC 100167/00 Sira MC 100168/00


EN standard EN14625 EN14626 EN14211 EN14212


The Serinus gas analyser series are utilised in many different applications including air quality monitoring stations, roadside monitoring, EPA networks and research organisations. Further specialist models will be progressively released.


The Serinus series ambient gas analyser derives its name from the genus (group) of the canary, which was the first effective ‘method’ used to detect harmful gases in coalmines. Just as the humble canary helped protect the health of early coal miners, so too will the new Serinus gas analysers play their part in helping deliver a cleaner, safer, healthier global environment.
