MIDI: New Flowmeter for SEMTECH^® HI‑FLOW 2

MIDI: for HI‑FLOW 2 users who want to “close couple” their methane emission measurement

When you (the user) want to measure the emission source directly, MIDI could be for you.

Traditional high-volume samplers rely on excess air entering the sampling system for total leak capture. This requires a suction fan with higher flow rate than the leak. Such fans require significant power which could drain your battery power if the application is extended.

However, when the leak can be directly connected (“close coupled”) to the flowmeter, the fan is not required – then the MIDI accessory flowmeter can be used. In this configuration, the total flow rate and the methane concentration are measured, and corresponding leak rate is calculated and reported.

The MIDI (when connected to the HI‑FLOW 2 Analyzer) can measure small or large methane leak rates with the same accuracy, precision, and traceability as the HI‑FLOW 2 Sampler. The MIDI operates as a plug-and-play module like the SAMPLER and requires no additional software features. The MIDI simplicity provides for inherent robustness by design.

The HI‑FLOW 2 MIDI accessory accurately quantifies and reports real‑time, average and peak flow rates when directly coupled to the wellhead, eliminating the need for an active fan. Leveraging the flow of the wellhead, the MIDI reduces power consumption of the HI‑FLOW 2 while providing precise flow and pressure data crucial for environmental monitoring.

As the world intensifies its efforts to combat climate change, abandoned and orphaned wells (AOWs) have come under increased scrutiny. These wells, often left unmanaged, can emit significant quantities of methane, a greenhouse gas with a warming potential many times greater than carbon dioxide.

To address this, regulatory bodies and carbon registries are turning to advanced technologies like high-volume samplers. Carbon registries, such as ACR at Winrock International¹, rely on accurate data to validate carbon offset projects. High‑volume samplers like the SEMTECH^® HI‑FLOW 2 provide critical measurements needed to certify emission reductions.

Almost all carbon registries allow the use of high-volume samplers to capture emission rates of orphaned and abandoned wells. They also allow you to directcouple such measurements, as long as the well-pressure is measured in addition to determining the methane leak rate. By integrating these devices into a monitoring, reporting, and verification (MRV) framework, operators can confidently document methane abatement and monetize their efforts through carbon credits.

EPA Update – The US EPA issued a press release “EPA Finalizes Rule to Reduce Wasteful Methane Emissions and Drive Innovation in the Oil and Gas Sector” announcing the final rule to reduce methane emissions from the oil and gas sector on November 12, 2024. According to the press release “EPA estimates that this rule alone will result in cumulative emissions reductions of 1.2 million metric tons of methane (34 million metric tons CO₂-equivalent) through 2035 — the equivalent of taking nearly 8 million gas-powered cars off the road for a year — and will have cumulative climate benefits of up to $2 billion.” Read the press release on the EPA website and learn more about the Methane Reduction act here.

Montrose Environmental’s Insight Blog Why We Recommend HI‑FLOW 2 For Voluntary QMRV projects. In the blog, Dr. Booker, Sensors’ CTO explains why the SEMTECH^® HI‑FLOW 2 is the best choice for use in Quantification, Monitoring, Reporting, and Verification (QMRV) projects. “The HI‑FLOW 2 offers a best-in-class dynamic range of 0.0005 to 25 CFM. This is a very large dynamic range that encompasses the expected range of sampled flow rates and concentrations.”.

Heath Consultants’ LinkedIn post highlights how the SEMTECH^® HI‑FLOW 2 ensures your EPA OOOOb sampling is done correctly, meeting EPA standards measuring both low and high sampling requirements.

Product News

Sensors showcased the SEMTECH^® HI‑FLOW 2 and the eREM, our new laser based, open-path, continuous monitoring system for fugitive methane at CH4 Connections in Fort Collins, Colorado in October. The eREM, created in collaboration with Physical Sciences, Inc. was demonstrated during the event.
