* Each meter is calibrated to determine its flow capacity at a given velocity, which has been
established as 32.808 ft/s (10 m/s) for the meter capacity (Range DN). The meter capacity expressed
in gpm is recorded on the meter nameplate.
The meter capacity is the base upon which maximum and minimum limits for range settings and
outputs are established.
Flow velocity can be determined as follows:
Meter Capacity:
Flow Velocity (ft/s) = (Operating gpm x 32.808)/Meter Capacity
NOTE
The maximum meter flow range is a function of the signal converter used. The maxi-
mum flow range can not exceed the meter capacity.
