piston or pipe prover
piston or pipe prover
(OP)
LS,
For a calibration unit for positive displacement flowmeters for fluids, we are investigating the possibility of a piston or pipe prover. Does anyone have experience with these provers, and are there manufacturers of standard provers.
thanks,
DYV

RE: piston or pipe prover
You're looking for a "meter proving system". I operated one like this for loading ships off of Puerto Coveñas Marine Terminal, Colombia.
Do one prove run on each change of products or when some property change is noted on a shift of crudes, etc., temperature variations and ... we pushed the button on shift changes too, just for teaching the operator trainees good habits.
How big you need?

Several prover types exist. If applicable, consider low-volume provers or rental prover services.
