STANDARD PERFORMANCE
Accuracy:
Note: The accuracy of a product before shipment is
defined as totalized value at the result of calibration
test in our water actual flow test facility.
Calibrated conditions in our water actual test facility
are as follows:
Fluid temperature; 20 ± 10°C
Ambient temperature; 20 ± 5°C
Length of straight runs;10 D or more on the
upstream side; 5 D or more
on the downstream side
Reference conditions; Similar to BS EN29104
