Daniel® Pipe Provers
Exact measurement of
liquid flow requires on-site meter calibration with liquid at operating
conditions. Pipe provers from Daniel perform that important task,
calibrating turbine, positive displacement and Coriolis meters in the
field.
Pipe provers from Daniel automatically record flowmeter output during
displacement of metered flow through the prover’s known volume. The
comparison of meter output to the known volume establishes meter
calibration factor. Applying Meter Factor - the number that corrects a
meter’s inaccuracy -- results in more precise volume measurement for
applications that include custody transfer and fiscal measurement. Pipe
provers offer the advantage of continuous flow through the meter being
calibrated.
Bi-directional provers offer long-term reliability with minimum
maintenance. Uni-directional provers flow continuously with minimum
pressure loss. |
