The rotary gas meters GM4 and GM16 meet the highest demands for reliable and precise reference measurement of smallest quantities up to 0.01 m³/h. They operate according to the direct displacement principle (RPD - rotary positive displacement), in which two counter-rotating pistons convey a fixed volume from the inlet to the outlet of the gas meter with each full revolution. Due to the specially shaped pistons, absolutely pulsation-free operation can be achieved (patent pending). They achieve an excellent measuring accuracy of 0.5 % MW + 0.005 % EW. Both versions are suitable for operation up to 6 bar overpressure. With continuous, absolutely pulsation-free and highly precise flow measurement, the reference gas meters from Ehrler Prüftechnik are the gold standard in the field of small volume measurement. Features: Reference measurement of small flow rates Continuous and absolutely pulsation-free Overpressure operation Excellent measurement accuracy Robust & compact design

The Magnet UV tamper-evident seal is an antimagnetic sticker seal. It is designed to control the protection of metering devices. It consists of a sticker base with a protective layer, a transparent plastic capsule, and a magneto-sensitive suspension inside the capsule. The sticker base has a special inscription - "OPENED" - that appears when there is an attempt to remove the seal from the surface. The inscription does not disappear if the sticker is attached back on. The capsule features a UV glow effect, which makes it easy to check the integrity of the seal in poor lighting conditions. The magneto-sensitive suspension irreversibly changes its pattern when an attempt is made to influence the meter with a magnet with the intention to alter the readings. Clixar manufactures two types of Magnet UV seals that have different sensitivity thresholds - 50 mT and 100 mT. The transparent capsule makes it possible to protect
