Natural Gas Measurement

DirectMountSystem - How the right choice of valve technology supports an “Every Drop Counts” Operation

How the right choice of valve technology supports an “Every Drop Counts” Operation.
Gas prices are increasing, regulations expanding, and businesses must cater to environmental protection. These factors demand an “Every Drop Counts” approach for operating natural gas installations.

There is no reason to specify DIN 19213 instead of IEC 61518

DirectMount System - There is no reason to specify DIN 19213 instead of IEC 61518.

IEC 61518 (DIN EN 61518) is the global standard for Manifold-to-Transmitter Flange Connections. This standard has been issued in 2001. IEC 61518 is based on the German standard DIN 19213 (latest revision 1991 before superseded by IEC 61518). So, basically DIN 19213 is not anymore used with the exception of revision 1980, which is still specified in some standards. IEC 61518 has been prepared by subcommittee 65B and I was one of the subcommittee members. I am really surprised that DIN 19213 is still used after all these years, although there is no technical reason to specify this obsolete standard.

Small, but powerful: Low torque for a smooth operation

DirectMountSystem - How to ensure a smooth operation of different valve head units.

During my last 12 years in the instrumentation business I get asked at which pressure is a manifold useable and still turnable? As well as, what is the difference between a One-Piece Design and a Two-Piece Design Stem?

How to ensure compliance with BLM rules

How to ensure compliance with BLM rules.

In my new blog post, I would like to deal with some new rules and regulations. These directives concern the Bureau of Land Management orifice meter measurement (short form: BLM). I am the Sales Director – Americas. From this position, I have seen how the American oil and gas industry is struggling with the new BLM rules.

Useful little helpers in the measurement of natural gas

DirectMountSystem - How to eliminate gauge line errors in natural gas applications.

Field research and testing conducted by Southwest Research in San Antonio, Texas and the Pipeline Gas Compressor Research Council (PCRC) confirmed that pulsation created by compressors, flow control valves, regulators and some piping configurations may create undesirable levels of Square Root Error (SRE) and/or resulting Gauge Line Error (GLE). Pulsation at the orifice meter is a major source of lost and unaccounted for natural gas. These errors create either large economic gains or losses for the buyer and seller along a natural gas pipeline system.

Eliminate leaks and overpressure

DirectMountSystem - Eliminate leaks and over-pressure by using mini valves and rupture disc holders.

Mini valves are located at both ends of the sampling cylinder. They have a shut-off function and prevent a leakage of the medium. Rupture disc holders provide protection against overpressure in the sampling cylinder. Learn more about mini valves and rupture disc holders.

Save money with the bubble-tight Soft Seated Valve Design

DirectMountSystem - Save money with the bubble-tight Soft Seated Valve Design.

Besides to the well-known hard seated valves Soft Seated Valves are considered to be bubble-tight and leak-free. Bubble-tight shut off is required to achieve accurate measurement through the use of instrumentation valves and manifolds.
