Max permission error:
From Qt including Qt to Qmax: +/-3% for hot water and +/-2% for cold water.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:
3.6V/t<Q
V=batch volume of the water in liters
T=time per batch in seconds
Q=maximum flow rate in m3/h
For maximum service life should follow:nhV/1000<E
n=number of batch per hour
h=number of working hour
V=batch volume of the water in liters
E=maximum delivery in m3
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.
