Abstract
A flowmeter proving device and method for use in proving a flowmeter in situ under operating conditions comprises a pair of standard Coriolis based mass flowmeters (2, 3) which are connected together in series by a conduit (7) connecting the fluid outlet (23) of the first flowmeter (2) to the fluid inlet (32) of the second flowmeter (3). A valved fluid supply conduit (4) is connected to the fluid inlet (22) of the first flowmeter (2), and a valved fluid return conduit (8) is connected to the fluid outlet (33) of the second flowmeter (3). These supply and return conduits (4 and 8) enable the device to be connected to a fluid flow line containing a flowmeter which is to be proved such that fluid flowing in the flow line will flow in series through the flowmeter to be proved and the two flowmeters (2 and 3) of the proving device.
The device includes control means which is operative to use the second flowmeter (3) as a master meter to check the accuracy of the flowmeter to be proved, and the first flowmeter (2) as a check meter for the master meter (3).
The device includes control means which is operative to use the second flowmeter (3) as a master meter to check the accuracy of the flowmeter to be proved, and the first flowmeter (2) as a check meter for the master meter (3).

A flowmeter proving device for use in proving a flowmeter in situ under operating conditions, comprising first and second standard Coriolis based mass flowmeters which have been calibrated to a predetermined accuracy specification, means connecting the fluid outlet of the first flowmeter to the fluid inlet of the second flowmeter to connect said flowmeters in series, supply and return conduits respectively connected to the fluid inlet of the first flowmeter and to the fluid outlet of the second flowmeter to enable the device to be connected to a fluid flow line containing a flowmeter which is to be proved such that fluid flowing in the flow line will flow in series through said flowmeter to be proved and said first and second flowmeters of the proving device, and control means for connection to said first and second flowmeters and to said flowmeter to be proved to receive flow measurement signals therefrom, said control means being operative to use one of said first and second flowmeters as a master meter to check the accuracy of the flowmeter to be proved and the other of said first and second flowmeters as a check meter for said master meter.
2. A device according to claim 1, in which the first and second flowmeters are substantially identical to each other.
3. A device according to claim 1 or claim 2, in which the accuracy of each of the first and second flowmeters is calibrated to an uncertainty of about 0.03% or less.
4. A device according to any one of the preceding claims, in which the first and second flowmeters are mounted on a common base.
5. A device according to any one of the preceding claims, including temperature and pressure sensors for providing the control means with temperature and pressure measurements of fluid flowing through the device.
6. A device according to claim 5, in which the fluid outlet of the first flowmeter is connected to the fluid inlet of the second flowmeter by an intermediate conduit, and the temperature and pressure sensors are mounted on said intermediate and conduit.
7. A device according to any one of the preceding claims, in which the supply and return conduits each contain a shut off valve.
8. A device according to any one of the preceding claims, in which the control means includes a central processing unit which is operative to receive and process flow measurement signals provided simultaneously by the master meter and the check meter and the flowmeter to be proved during the same time interval.
9. A method of proving a flowmeter in situ in a flow line under operating conditions using a proving device according to any one of the preceding claims, comprising connecting the supply and return conduits of the proving device to the flow line upstream or downstream of the flowmeter to be proved and on opposite sides of a shut off valve in the flow line, closing the shut off valve so as to cause the fluid in the flow line to flow in series through the flowmeter to be proved and the first and second flowmeters of the proving device, obtaining a measurement of the fluid flow rate from each of the flowmeters, comparing the flow rate measured by the flowmeter to be proved with the flow rate measured by one of the first and second flowmeters of the proving device to check the accuracy of the flowmeter to be proved, and comparing the flow rate measured by the other of the first and second flowmeters of the proving device with the flow rate measured by said one flowmeter to confirm the accuracy of said one flowmeter.
