Summarize:
Portable water meter testing meters is designed and developed in the usage of water meter testing at spot during working condition, which can test out the water meter precision fast and correctly. It's also the must testing meters of the Metric bureau to do the periodically test for on-line working water meter.
The device is to be directly connected to the water device after tested water meters, once the water starts running when turning on the valve, comparing the collected figures showed on tested water meters and collected figures on the testing device, which is the simple way to mark out the precision of the tested water meter. And it's the most ideal device for the periodically test for on-line working water meter.

Technical performance

1) Features: It features with Mass Integrate Circuit, advanced designs and good structure, as well as decimal system for counter circuit. And also functioning as instantaneous flow and accumulative flow shown at one time on one LCD screen, with clear figure, non-modulus and non-unit conversion and hand-handle accumulative flow turn back to 0 after powered on. With all these functions, times of water meters can be repeatedly tested without any water stop and readjustment for the flow rate during every tested. So it's good enough as time-saving, energy-saving, simple operating, accurate reading, high precision, stable, high anti-jamming, overall function, long life time, easy maintenance and portable, etc
