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.

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.

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.

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.

In many industries, orifice meters are used for measuring the rate of flow of liquids and gases. In the past it was common to connect instruments with the main piping by using orifice meters, primary isolation valves, fittings, tubing (impulse piping), remote mount manifolds, pipe stands and further accessories. This conventional installation method is time- and cost-consuming accompanied by some technical issues.
