Gas meters - Import export

The test bench is designed for calibration with critically operated nozzles of domestic gas meters or others such as diaphragm gas meters, ultrasonic meters, thermoelectric gas meters. The test bench is specially designed for the calibration of domestic gas meters (bellows gas meters, ultrasonic meters, thermoelectric gas meters). The test bench is modular - 1x6 to 4x6 clamping positions for the gas meters can be combined. Due to the modular design 1 to 12 gas meters can be tested simultaneously. In parallel, up to twelve additional test pieces can be adapted, run in and leak tested. A magazine consisting of three critical nozzles is used as flow transmitter. Optionally, a nozzle drum with nine combinable nozzles can be used. This allows the generation of up to 512 different flow points with highest accuracy.

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 ALTOSONIC V12 is a 12-chord ultrasonic custody transfer (CT) flowmeter for natural gas. It has been designed to offer the best possible measurement accuracy, not only during calibration under ideal conditions but also during less ideal conditions in the field. As a result, ALTOSONIC V12 is the first ultrasonic flowmeter that was certified to OIML R137 class 0.5 by NMi. Due to its design with 12 acoustic chords a flow conditioner is no longer required; standards such as AGA9, ISO 17089 and MID are met with just 5D straight inlet piping. CBM flowmeter diagnostics are standard and give an exact picture of what is happening inside the flowmeter. With the optional KROHNE Care diagnostic expert system an integrated web server becomes available that presents the results as an easy to access webpage – in plain language.
