Embodiment Construction

[0021] figure 1 The illustrated embodiment of the flow meter verification device comprises a support base 1 on which two identical standard Coriolis mass flow meters 2, 3 are mounted side by side. The size of the flow meter used (nominal flow range) will depend on the size of the operating flow meter that needs to be verified by the device. In the illustrated embodiment, each flow meter 2, 3 comprises an ELITE(TM) sensor manufactured by Micro Motion Inc (e.g. model CMF200 has a nominal flow range of 725 kg / min) and is responsive to an output signal from the sensor for Transmitters 26, 36 (not shown in figure 1 show). The transmitter, which may be an ELITE model RFT9739 transmitter also manufactured by Micro Motion Inc., may be mounted directly on the sensor housing or may be provided separately for remote mounting and provide appropriate cabling to the sensor.

[0022] Each flow meter sensor 21, 31 includes a fluid inlet 22, 32 and a fluid outlet 23, 33 on opposite ends of ...

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).

Description

technical field [0001] The present invention relates to a flowmeter inspection device and method for field inspection of flowmeters under actual operating conditions. Background technique [0002] The device is primarily used to verify mass flow meters, especially Coriolis mass flow meters, but can be used to verify the accuracy of any flow meter placed in an operating position where fluid normally flows and capable of measuring internal or external fluid properties. Such flow meters include specific gravity, viscometer and volumetric flow meters as well as mass flow meters. [0003] Coriolis mass flow meters are known and disclosed in a number of patents such as US Patent Nos. 4444059 and 4422338, all of which describe mass flow meters using vibrating tubes to create a Coriolis effect relative to mass flow. US Patent No. 4491009 describes a vibrating tube hydrometer based on a Coriolis mass flow meter. The ability of a Coriolis effect mass flow meter to measure density al...
