Good wearing resistance Rust protection Good corrosion resistance Pass GB/T778-2007 national standard
Good Metrological Performance
The error of flow characteristic curve is stable. It transits smoothly. Each performance indicators of our products is in conformity with the GB/T778-2007 national standards. And the starting flow rate shall be superior to the national standards.
High Sensibility
The water meter substantially decreases the specified value of starting flow rate by using the Flow Continuity Theory and Jet Principles. It can be below 0.002m3/h. And the measurement level can satisfy the requirement of grade C and D so as to measure the drippings.
Good wearing resistance
Imported ABS construction plastics are used in the cassette mechanism so as to increase its wearing resistance and extend its lifetime. It can still accurately and reliably measure after being tested of increasing wearing resistance and pressure resistance. Rust protection outside the shell and spraying plastics treatment greatly increase the corrosion resistance of the water meter.
