The bench is available to use the volume comparison method to test water meters DN40mm, DN50mm, DN80mm, DN100mm and DN150mm.The equipment can supply whole bench characters analysis and errors inspection to a single water meter. To ensure the equipment smoothly operation, Mechanical method only and mechanical combined with cameras are selective ways, the later gives more convenient. Products are offered to the manufacturer of the water meter, repair factory, measure department, large-and-middles-scale industrial and mining enterprises, and railway water and electricity ones. The product is well known by the features of High precision, easily operation and simple maintenance.

1.      Device accuracy: 0.2

2.      Device calibration method: the volume comparison.

3.      Standard graduate cylinder: gourd-style double-necking with 2 gauges, the lower half of one gauge have a volume of 0.1m3 and the whole is 0.5m3; another gauge has the lower half 1m3 and the whole 3m3. The necking part of the standard measure of the corresponding volume of water per liter higher than the national standard height.

4.  Instantaneous flow meter: measured precision ≤ level 2.5, is divided into four glass rotor flow meter, one for the shunt orifice flow meter:

4.1 LZB-25，70-700L/h，DN15 ball valve control.

4.2 LZB-50，450-8000L/h，DN25 ball valve control.

4.3 LZB-80，7-35 m3/h，DN50 ball valve control.

4.4 LZB-25，40-180m3/h，DN150 Worm manually control valve , a ball valve DN25 for the flow fine-tuning purposes next to shunt orifice flow meter..

5. Clamp meter devices: pneumatic, telescopic distance: about 240mm.

6. Commutator: piston.

Trip distance: 180mm.

air source pressure: 0.35～0.5MPa.

When pressure of gas source≥ 0.4MPa, the time tolerance of the Commutator movement is less than 0.1% as one shortest flow time go.

7. Water pressure: 0.25～0.4MPa.

Water pressure should be no discernible pulse phenomena, the slow changes in water pressure caused by fluctuations in the instantaneous flow coefficient is not more than 1%.

8. Power: 380V, 50HZ three-phase four-wire.

9. Calibration dimensions of the test bench are nearly: L × b × h is about 7400 × 2800 × 3400mm.

10. Total weight of bench: 3t.
