ABSTRACT:
A calibratable turbine wheel gas meter includes a tube member having a lateral stud which carries a counter. An exchangeable measuring insert comprises an inlet member including an inlet body and an outlet member including an outlet body and is inserted into the tube member to abut a stop formed in the outlet member. Together with the tube member the inlet member forms a pressure space to measure the static pressure therein. The outlet member is formed integrally with the outlet body and is combined overlappingly with the inlet member. The inlet member and the outlet member define a passage in which the blades of a turbine wheel are located and the shaft of the turbine wheel is journalled in a bearing housing disposed in the outlet body. A pulse generator is arranged to cooperate with the turbine wheel and generates pulses, the number of which is dependent on the volume of gas passing through the passage. Each measuring insert is calibrated by comparison to a standard measuring insert. The counter is drivingly connected to the shaft of the turbine wheel by means of a transmission shaft and the counter is adapted to the respective calibrated measuring insert by exchanging the associated transmission gear.
