ABSTRACT:
A fluid flowmeter prover uses a measuring cylinder in series with a flowmeter to calibrate the flow meter. The cylinder has a piston which travels in synchronism with the fluid, the flow rate of which is to be measured. At the downstream end of the cylinder, a poppet valve connected to and within the piston opens to allow the fluid to pass through the piston. The poppet valve has a valve rod connected to a first coupling. A second coupling engages the first coupling and through a motor draws the valve and piston to the upstream end of the cylinder where they disengage, releasing the valve and allowing it to close for another run. The cycle repeats when the second coupling is driven down to reengage the first coupling.
