Embodiment Construction

[0017] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0018] like figure 1 As shown, the open-close cycle flowmeter calibration device includes a water storage tank 1 filled with medium water 2, and the water storage tank 1 is connected to a surge tank 4 through a first power device, the first power device is preferably an electric pump 3, the The downstream of the surge tank 4 is connected to a primary buffer tank 5 and a secondary buffer tank 10. Several standard flowmeter pipelines 7 with different diameters and specifications are arranged between the primary buffer tank 5 and the secondary buffer tank 10. Several standard flowmeter pipelines 7 is used to install the standard flowmeter 8, and several standard flowmeter pipes 7 are equipped with a cut-off unit. An electric switch 9 is arranged on t...

Abstract

The invention belongs to the technical field of automation instruments and in particular relates to an open-close circuit circulating flow meter verification apparatus comprising a surge tank, a standard flow meter and a to-be-detected flow meter and the three devices are orderly connected. The surge tank is connected with a water storage pool via a first power device; the to-be-detected flow meter is communicated with the water storage pool via a first metering tank; a first stop valve is arranged between the to-be-detected flow meter and the first metering tank; the water storage pool, the first power device, the surge tank, the standard flow meter, the to-be-detected flow meter and the first metering tank form an open-circuit circulating detection loop; the surge tank is communicated with a conflux tank via a second power device; the to-be-detected flow meter is communicated with the conflux tank; a second stop valve is arranged between the to-be-detected flow meter and the conflux tank; and the conflux tank, the second power device, the surge tank, the standard flow meter and the to-be-detected flow meter form a close-circuit circulating detection loop. Detection of the open-circuit circulation and the close-circuit circulation can be achieved; the to-be-detected flow meter can be verified; and the open-close circuit circulating flow meter verification apparatus requires low construction cost and less power loss, reduces energy consumption and has high utilization rate.

Description

technical field [0001] The invention belongs to the technical field of automatic instruments, in particular to a calibration device for an open-close cycle flowmeter. Background technique [0002] At this stage, the working principle of my country's liquid flow calibration device is: install the tested flowmeter on the calibration device, start the liquid circulation system, make the liquid flow through the standard flowmeter and the tested flowmeter, and synchronously operate the tested flowmeter and the standard flowmeter. Flowmeter, compare the output flow values ​​of the two, so as to determine the measurement accuracy and repeatability of the tested flowmeter. [0003] Although simple and easy to implement, this type of device has the following disadvantages: [0004] 1. Due to the limitation of standard containers, it is often impossible to realize continuous detection or even single-point detection of flow points. At the same time, high requirements are placed on the...
