Embodiment approach

[0099] In addition, this invention is not limited to the said embodiment.

[0100] For example, the flowmeter in the above-described embodiment is a Coriolis flowmeter, but may also be a flowmeter of other measurement principles such as a thermal flowmeter, a differential pressure flowmeter, and an ultrasonic flowmeter.

[0101] In addition, the channel switching part 8 of the above embodiment connects the electronic balance introduction channel 6 and the auxiliary storage part introduction channel 7 to one three-way solenoid valve (the second three-way solenoid valve 83) to switch, but it can also be switched as Image 6 As shown in (A), the electronic balance introduction passage 6 and the sub-reservoir introduction passage 7 are connected to the circulation passage 4 through the three-way solenoid valves 8x and 8y, respectively. According to the above configuration, although the difference in pressure loss may be increased compared with the above-mentioned embodiment, the d...

Abstract

The present invention provides a flowmeter inspection system and a flowmeter inspection method, the flowmeter inspection system makes a fluid flow through a flowmeter to be inspected, and measures a flow rate flowing through the flowmeter to be inspected using a measurement section different from the flowmeter to be inspected The fluid of the meter is used to check the inspected flowmeter, and the flowmeter inspection system includes: a storage part, which stores the fluid; a flow channel, which makes the fluid pass between the storage part and the inspected flowmeter flow; a measurement part introduction channel connected to the flow channel to guide the fluid to the measurement part; and a flow channel switching part that switches the flow channel and the measurement part introduction channel from the flow The pressure loss of the flow path from the path switching portion to the storage portion is the same as the pressure loss of the flow path from the flow path switching portion to the measurement portion.

Description

technical field [0001] The present invention relates to a flow meter checking system and a flow meter checking method for checking the accuracy of a flow meter such as a fuel flow meter, for example. Background technique [0002] As shown in Patent Document 1, in a conventional flowmeter inspection system, the flowmeter to be inspected is connected to a circulation channel through which fuel circulates, and the accuracy of the flowmeter to be inspected is checked by passing a fluid at a predetermined flow rate through the flowmeter to be inspected. [0003] Specifically, the circulation passage is connected to a container for storing fuel, and a needle valve for flow adjustment and a reference flow meter as a reference for the flow meter to be inspected are sequentially provided downstream of the flow meter to be inspected and upstream of the container. In addition, an electronic balance introduction channel is connected between the reference flow meter and the container in ...
