Problems solved by technology

Except for a few water tanks in Weifang and Liaoning where the conditions are better, the rest of the water tanks have problems such as outdated equipment, backward technology, and low verification accuracy to varying degrees, which brings great inconvenience to the verification of the current meter.
The length of the existing linear open channel water tank is about 130-180 meters, which is bulky and requires high construction and maintenance costs. System damage is serious, and even safety accidents occur

Abstract

The invention relates to a portable flow meter verification device, which adopts a split structure design and uses a circular ring-shaped water tank (1) to replace the traditional straight open tank. Compared with the straight open tank, the annular water tank (1) has a simple structure, It is convenient to carry, can be quickly disassembled and assembled on site, and the device occupies a small space and has low production and maintenance costs, which can provide more abundant verification conditions for the flow meter (6), and effectively reduce its verification cost.

Description

technical field [0001] The invention relates to a portable flow meter verification device, which belongs to the technical field of flow meter verification. Background technique [0002] my country is a country rich in water resources. Flow velocity measurement plays an extremely important role in grasping the natural laws of water resources movement, rational development and utilization of water resources, and flood control and disaster relief. With the continuous development of science and technology, the technical level of flowmeters is also constantly improving, and a large number of advanced flowmeter products have appeared. Among them, the portable rotor flowmeter is favored by hydrologists because of its simple structure, high reliability, low price, and strong environmental adaptability. [0003] In order to ensure the accuracy of the flowmeter, according to the national industry standard (SL / T150-95) "Verification Method of Rotor Flowmeter in Straight Open Slot", th...
