Thermal mass flow meters
Upstream oil and gas thermal mass flow meter solves EPA reporting challenges by providing accurate flow data regardless of gas composition change.
Engineers can field adjust gas composition on thermal mass flow meters in the field for flare, vapor recovery unit (VRU), and storage vessels without sending the meter back to the factory for recalibration. It is a user-customizable gas mix feature that allows oil/gas engineers and operators to create custom gases or gas mixtures to compensate for gas compositional changes in the field without accuracy loss. It provides accuracy of +/- 0.5% with readings above 50% of full scale for flow meter air measurement and other gases; built-in flow conditioning (inline version); has high turndown to handle low flows to high flows during upset conditions; multivariable outputs; flow ranges up to 60,000 sfpm (305 smps).
