1 Requirements
Recommended meter sizing
The following points should be observed when sizing the Coriolis
meter for proving applications:
•
At flow velocities of 3 to 55 ft/s (1 to 17 m/s), the
optimum flow signal stability for proving is achieved.
Over wider turndowns, it may be necessary to utilize a
different meter factor for lower rates.
•
Minimum flow rates with 0.8 specific gravity fluid are
recommended as shown below.
Nominal diameter
DN 15 (½ in)
DN 25 (1 in)
DN 50 (2 in)
DN 80 (3 in)
DN 100 (4 in)
DN 150 (6 in)
•
The proving measurement time should be sufficient to
get a stable flow, and provide enough pulses to the
counter.
•
The flowing velocity of 55 ft/s (17 m/s) through the meter
should not be exceeded.
•
Cavitation or void fraction in the fluid should be avoided.
•
Noise or vibration at frequencies that affect the sensor
should be eliminated.
•
Flow and density instability should be avoided.
