Gas Compressor Packing Leak Application Solutions with Thermal Mass Flow Meters

Accurate Methane Gas Measurement

Operating in the Oil & Gas industry is tough. Emissions regulations result in the need to measure, monitor, and report emissions. Methane emissions are a potent greenhouse gas that require flow measurement and leak detection to avoid regulatory fines.

Packing leaks from gas compressors are now covered under the Quad O (OOOO) regulation. Flow meters can help with:

  • Identify emission issues due to packing vent leakage
  • Accurate emissions data during a blowdown event
  • Avoid fines due to methane emissions and misreporting

Advanced Thermal Mass Flow Meters

Meet Quad O requirements

Fox Thermal flow meters help you meet the new OOOOb emissions reporting requirements for gas compressors. Our flow meters meet and exceed the accuracy requirements of the EPA, have extensive approvals, and have an in-situ calibration validation feature to ensure your meter is functioning properly.

Accuracy at very low flow rates

A flow meter that can handle very low flow rates of gas is ideal for gas compressors. Fox Thermal's mass flow technology is well-suited to measure very low flow rates - as low as 0.6 SCFM! Our flow meters are rugged, accurate, and perfect for use in oil & gas applications needing accurate and repeatable gas flow measurement.

Part of an advanced LDAR program

Monitoring flow rates of packing vent leaks to avoid packing failures allows users to gain insight on better mechanical seal maintenance as part of an advanced Leak Detection and Repair (LDAR) program. Understanding the relationship between flow rates and potential seal failures is key to avoiding emissions data issues.

Avoid Methane Emissions Fees with Accurate Instrumentation

The EPA's 40 CFR Part 60 Subpart OOOO (Quad O) rule is a US federal regulation meant to reduce VOCs and methane (CH4) emissions from oil and gas wells and facilities. Gas compressors are listed as applicable emission sources in this rule and the annual flowrate monitoring of rod packing seal leaks is required.

Accurate flow measurement solutions, like thermal mass flow meters, are key to monitoring in these applications due to their ability to measure accurately at very low flow rates.

Gain Confidence with Calibration Validation

Is your flow meter measuring as accurately today as it was upon installation? Calibration validation can help you find out. Models FT1, FT4A, and FT4X flow meters are equipped with the CAL-V™ Calibration Validation feature that permits the user to validate the calibration in the pipe, at process conditions. At the conclusion of the test, the meter will display a pass/fail message and the CAL-V™ data is saved in the meter for look-up at any time. It is an operator-initiated test and takes approximately three minutes to complete. When initiated using the FT View™ software, a certificate of the test results can be produced for record-keeping.
