This apparatus employs negative pressure extraction to conduct simultaneous running-in tests across multiple stations (48–60 meter positions).
Each station features a throttle valve for independent flow regulation, while flexible couplings facilitate meter installation and removal.
Power is supplied by a medium-pressure blower with a flow rate exceeding 360m³/h and power consumption not exceeding 1.5kW.
This apparatus is suitable for gas meter manufacturers conducting gas-flow running-in tests on new meters.
