Large water meter test system
Test systems for large and combination water meters up to DN 300 – with volumetric or gravimetric reference and test points up to 1,000 m³/h.
What the system delivers
For large flow rates the system works with a volumetric reference via verified vessels or with gravimetric weighing. Pumps and control valves keep the test points stable throughout the measurement.
Meters are changed using hydraulic clamping systems with seal set change, so even meters up to DN 300 can be changed at the test position without a crane. Test programmes and reports are identical to the domestic systems.
The systems are used by water utilities, verification bodies and accredited calibration laboratories.
