PGME designs and manufactures diaphragms to measure the volume of gas transiting through a pipe from a pressure difference created by an orifice plate. The two models, single room or double Chamber, conform to the ISO 5167 standard which guarantees the accuracy of the metering. The diaphragms can therefore be used for transactional measurements.
Both models can be integrated into a full counting ramp, consisting of straight lengths calibrated upstream and downstream, of flux rectifier, the design and manufacture of which is mastered by PGME. A safety screw prevents the pressure device from opening and protects operators from accidental opening. But the "double Chamber" version allows to change the orifice plate safely, without cutting the pressure in the installation.
A wide range according to CODAP or ASME, from 2 to 36 "in single room and from 2 to 20" in double room allows to cover your needs for pressures from 20 to 250 bar.
The annual dimensional and Visual verification of diaphragms can be performed by PGME. The company is approved by the French Ministry of industry to validate the conformity of the orifice plates with the ISO 5167 standard.
