Water flow standard device suitable for vibration environment

Abstract

The invention discloses a water flow standard device suitable for a vibration environment. The device is arranged on a platform arranged in a layered mode, and a water tank, a frequency converter cabinet, a flow stabilizing tank, a gettering filter and a water pump set which are connected through pipelines and valves are arranged on the first layer of concrete ground; the second-layer steel structure platform is provided with a detected meter pipeline, a compatible replaceable pipe section, an electronic scale weight self-loading system, a weight, a hydraulic system and a control circuit system; the third-layer steel structure platform is nested in the fourth-layer steel structure platform and is an independent weighing platform, and the structure of the third-layer steel structure platform is independent; and the fourth-layer steel structure platform is provided with a reverser and a water distributor. Compared with the prior art, the water flow standard device suitable for the vibration environment has the advantages that on the basis of being compatible with a standard meter method to improve the verification/calibration efficiency and not limiting the capacity (flow) range of ahigh-precision static mass method, the vibration isolation and wind prevention design is performed on the water flow standard device of the static mass method, and the device can adapt to industrialproduction plant environments with complex environments and limited construction spaces.

Description

technical field [0001] The invention relates to a standard device for verifying / calibrating a water flow meter, more specifically, the invention relates to a water flow standard device suitable for vibration environments. Background technique [0002] The water flow standard device is a measurement detection device widely used in the measurement error test of water meters, turbine flowmeters, electromagnetic flowmeters, ultrasonic flowmeters and other water flowmeters. It has been widely used in the fields of flowmeter manufacturing and measurement calibration services. [0003] For example, the German Institute of Physics and Technology (PTB) has developed a water flow standard device that is compatible with the static mass method and the dynamic mass method. It includes 3 binary balance weighing systems of different sizes, among which the strain gauge electronic scale The dynamic mass method is used for fast response, and the electromagnetic force compensation electronic s...

AI Technical Summary

Problems solved by technology

However, the above-mentioned water flow standard device using the static mass method requires a stable weighing basis, which cannot effectively eliminate the influence of nearby vibration sources in the factory (other production equipment or device operation, personnel construction, etc.), so it is mostly built in the laboratory environment Non-industrial production plant environment

In addition, please refer to figure 1 As shown, the above-mentioned water flow standard devices using the static mass method are mostly tiled layouts, which occupy a large area and have high construction costs. Many enterprises in the water flow industry are faced with the dilemma of limited plant area and capital scale. promote its utilization and development
