Test residential, commercial and fire hydrant meters from 2" to 10" with a 0.1% repeatable accuracy. Just connect this meter tester to your existing water meter to be verified and flow. Compare the reading on the meter and on the testing device. The meter must be at a full flow of liquid and 3' of straight inlet hose for proper accuracy.
The tester consists of a NIST traceable 3" turbine meter, NIST traceable 5/8" turbine meter, 3" gate valve, 3/4" ball valve and a pressure gauge. Inlet and outlet are equipped with brass NST fittings.
