Bell prover gas meter test bench is an equipment to test domestic gas meter G1.6-4, the flow range 0.016m3/h～6m3/h. It is an ideal testing equipment for gas meter factory and R&D institute.

FEATURES
1. The body of test bench is made of industrial aluminium, the central distance and height of clipping device are changeable.
2. The test bench can sample volume of bell prover, volume of tested meter and calculate testing error automatically.
3. The test bench has operation control panel to choose the type of tested meter and set up testing data, the operation is easy and intuitionistic
4. The test bench can convert right and left input gas and check the flow rate.
5. The bell prover can move up and down automatically and the gas-output valve can switch automatically.
