Magnetrol International has announced that its 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 tonnes/year of carbon dioxide equivalent to report greenhouse gas emissions.

“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 CO2, meeting the EPA requirements,” Magnetrol said.

Its 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 per cent of reading +0.5 per cent of calibrated full scale and exceeds the stated acceptable accuracy within this new EPA rule, the company stressed. Instruments are available for installation in line sizes from 15 mm up to more than 3,000 mm. 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 4-20 mA signal including Hart protocol.

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