Influence of Flowing Time on Metering Performance of Multi-jet Wing Water Meter
Multi-beam rotor water meter is the most widely used cold water measuring instrument at present.In this paper,the influence of the flow time of tap water on and off the valve on its metering accuracy is studied.The results show that the smaller the flow rate and the shorter the flow time,the more positive the indication error of multi-beam rotor water meter is.Under the condition of 50L/h flow point and 10s flow time,the indication error offset values of the three water meters are+10.83%,+13.15%and+10.71%respectively,all exceeding 10%.
