RITTER Bellows-type Gas Meters are applicable for measuring the volume of flowing inert and dry gases and are particularly effective at high gas flows. Please note that gases containing aggressive components or water vapour may reduce the life span of bellows-type gas meters, if the casing of the measuring unit (tinplate), the valve/control elements (polyamide) or the bellows (Perbunan®) should be attacked. Further details on the materials that may come into contact with gases can be found under »Materials«.

The desired measurement range can be selected from among 6 magnitudes (types) extending together as a whole from 40 ltr/h to 160 m3/h at a gas temperature ranging from -20 °C to +50 °C. The solidly soldered casing on the standard model is designed to withstand a maximum overpressure of 50 mbar (BG 40/100: 0.5 bar).
