Test
After meter has been inserted into the product line,
meter must be proved in order to obtain new meter
factor. This is usually accomplished by the use of a
displacement-type prover.
During testing, should repeatability not be obtainable,
check to make certain that pick-up coil is tight. If coil is
tight and results are still not satisfactory and assuming
prover is functioning properly, it may be necessary to
recheck rotor and platform bearing for possible damage
during installation. Proving the meter should be under
the same conditions of flow rate, pressure, temperature,
and liquid characteristics as exist during normal opera
-
tion of the meter.
For meter proving procedures, refer to API Manual of
Petroleum Measurement Standards, Chapters 4 and 12.
