Selecting the proper size of meter
For selecting the proper size should follow the table with maximum flow rate
(Q) in m3/h and the maximum daily delivery (E) in m3 as :
For maximum service life should follow:
For keeping the accuracy, the flow rate (Q) should be not less than Qt. The flow rate is easily calculate by the water was collected in a calibration tank for a measured period of time. For example, 15 liters are collected in 30 seconds, the flow rate will be: 3600/30×15=1800l/h.
For selecting the dial reading, the maximum dial reading should always exceed the highest expected batch volume.
