Abstract

The invention provides a non-full-tube flow calibration device, and relates to the technical field of flow measurement. The non-full-tube flow calibration device comprises a first water storage tank,a second water storage tank, a water pump, a communicating pipe and a simulated non-full-tube pipeline; the first water storage tank, the water pump, the communicating pipe and the simulated non-full-tube pipeline are communicated in sequence, and a water outlet of the simulated non-full-tube pipeline is arranged corresponding to the second water storage tank; the water pump is used for controlling water output amount of the first water storage tank, the simulated non-full-tube pipeline is provided with an opening, the opening is provided with a measured flow probe, the second water storage tank is used for receiving outlet water of the simulated non-full-tube pipeline, so that recorded data of the measured flow probe is compared with the total water amount of the second water storage tank. The technical problem in the prior art that the calibration method is complicated and operated difficultly is solved. The non-full-tube flow calibration device simulates the use environment of a non-full-tube flowmeter, and the accuracy of the measured flow probe is determined by comparing the total water amount of the second water storage tank with the data of the measured flow probe.

Description

technical field [0001] The invention relates to the technical field of flow measurement, in particular to a partial pipe flow calibration device. Background technique [0002] With the development of science and technology, there is an increasing demand for liquid level monitoring in municipal and water conservancy fields such as rainwater, sewage, reclaimed water, rivers, lakes, and roads. In recent years, the country has paid more and more attention to the liquid level measurement and monitoring data of urban rivers and drainage pipes. Flow measurement is now widely used flowmeter, flowmeter variety, can be divided into rotameter, throttling flowmeter, slit flowmeter, volumetric flowmeter, electromagnetic flowmeter, ultrasonic flowmeter and so on. Many flowmeters require that the liquid in the pipeline fills the cross section of the pipeline, and the flow rate of the liquid passing through the flowmeter is obtained by different methods. However, under some specific condi...
