Emission Measurement MVS 403-EM

Emission Measurement using the Cover Method or Suction Method

With the REGULATION OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL on the reduction of methane emissions in the energy sector and amending Regulation (EU) 2019/942 (EU Methane Emissions Regulation), the metrological detection of methane emissions during the technical operation of gas transmission and distribution networks becomes necessary.

Drilling Method

The emission quantity measurement using the suction method serves to accurately detect methane emission rates at identified leak points in the pipeline network. The measurement values obtained from this emission measurement correspond to the measurement at the leak point in the soil and should not be compared with surface measurements. The measurement setup is shown in the next image.

Up to six probes can be connected. In the MVS 304-EM, the flow rate is measured, and the concentration in the extracted gas flow is measured using the gas analyzer.

Cover Method

The emission quantity measurement using the cover method serves to accurately detect methane emission rates at the surface. The measurement values obtained from this emission measurement do not correspond to those at the leak point in the soil. The measurement setup is shown in the next image.

In the MVS 304-EM, the flow rate is measured, and the concentration in the extracted gas flow is measured using the gas analyzer. This method is characterized by its speed and simplicity in practical field applications. The measurement is completed within a short period.

If the outflow quantity is desired directly at the leak point, it can be measured with the MVS 304-EM and a cover cloth after excavation.

Emission Quantity Calculation

For the determination of the emission quantity and the creation of documentation for each measurement, a customer-specific internet portal is available.

MVS 304-EM

Up to six suction probes can be operated simultaneously on the mobile vacuum station, or alternatively, the cover can be connected for the cover method.

The handling of the MVS 304-EM is simple and user-friendly. A two-stage filtration system retains water and dirt. The filter can be changed easily with just a few steps.
