SYNCROTRAK® flow prover features include a simple mechanical operation, no hydraulics or pneumatics and equal upstream and downstream volumes. There is also no adjustment for changing line pressures which eliminates operator error thus assuring superior and consistent proving results.

The SYNCROTRAK® flow prover meets the most stringent accuracy requirements of custody transfer meter proving or laboratory flow meter calibrations. Because of its small size, the rugged and reliable SYNCROTRAK flow prover is ideal for both portable and stationary applications. The highest accuracy, low pressure drop and smooth operation make the SYNCROTRAK flow prover the number one choice for proving coriolis mass flow meters, turbine meters and all types of flow meters.

Applications & Operations

Applications:

The SYNCROTRAK® flow prover meets the most stringent accuracy requirements of custody transfer meter proving or laboratory flow meter calibrations. Because of its small size, the rugged and exceptionally reliable SYNCROTRAK® is ideal for both portable and stationary applications.

The combination of highest accuracy, low pressure drop and smooth operation make SYNCROTRAK® flow provers the best choice for proving all flow meter types including coriolis mass meters.

Operations:

In the stand-by mode the piston is down stream and stationary. The piston's inner flow-through valve is open (i.e., slightly up-stream of the main piston body), allowing free flow of the fluid through the flow prover's measurement cylinder with insignificant pressure loss.

When the operator starts a proving run sequence (Figure 1), the computer then signals the explosion-proof motor to pull the piston to the up-stream position. The piston is then completely unlatched from the chain drive return mechanism. The low drag piston traveling down the smooth bore tube is now free to follow the fluid flow with the least possible effect on the flow stream. When the piston is released, the flow-through valve closes by spring tension (Figure 2). The piston is now synchronized with the fluid velocity.

Figure 2


After the piston has been released, and after a short run-up, the precision optical start of volume switch is actuated, sending a signal to the proving computer starting the timing sequence. The piston continues downstream with the flow. Upon reaching the end of volume switch a signal is sent to the proving computer stopping the timing sequence. Just after passing the end of volume switch, the piston shaft is stopped by a mechanical stop. The flow-through the prover pushes the perimeter of the piston further downstream, opening the flow-through valve, and allowing the flow to continue with little to no pulse or surge in line pressure.

To begin the next proving run sequence, a signal is sent from the proving computer, activating the return mechanism, pulling the piston to the upstream position, where it is released to obtain another data point.

CONDAT® Interface Unit

The CONDAT® is a MS-DOS -based data acquisition and processing system for flow meter proving. Three main proving modes are supported, standard volume using API tables, time and uncorrected volume, and the inferred mass proving mode, which simplifies the proving of mass flow meters, such as the coriolis mass meter. The CONDAT® system utilizes double chronometry per API 4.6. It is suited for all prover types, including bi-directional, unidirectional, piston provers and even master (transfer) provers. The CONDAT® system is a time proven system with many satisfied customers.
