Abstract

The embodiment of the invention provides a pipeline flow meter, and aims at solving the problem that accurate flow monitoring cannot be carried out aiming at a non-full flow state of a pipeline in an existing pipeline flow meter. The pipeline flow meter provided by the embodiment of the invention comprises a rotating shaft, a blade, a liquid level sensor, a speed measurement device and an arithmetic device, wherein the rotating shaft is used for carrying a blade; the blade is used for rotating around the rotating shaft as the axis under the drive of a liquid in the pipeline; the liquid level sensor is arranged on the blade and is used for sensing the liquid height of the liquid in the pipeline; the speed measurement device is connected with the rotating shaft and is used for generating flow rate data of the liquid in the pipeline on the basis of the rotating speed of the blade; the arithmetic device is electrically connected with the liquid level sensor and the speed measurement device and is used for generating flow data of the liquid in the pipeline according to the liquid height, the flow rate data and known pipe diameter information.

Description

technical field [0001] The invention relates to the technical field of pipeline measurement, in particular to a pipeline flowmeter. Background technique [0002] As the population density continues to increase, the water supply pipeline system, as an important part of municipal construction, faces more complex water demands. In order to ensure the normal operation of the tap water pipeline system, it is necessary to monitor the flow of the fluid in the tap water pipeline. However, the existing pipeline flowmeter can only monitor the flow of the pipeline in the state of full flow. Traffic data is not accurate. Contents of the invention [0003] In view of this, an embodiment of the present invention provides a pipeline flowmeter, which solves the problem that the existing pipeline flowmeter cannot perform accurate flow monitoring for the non-full flow state of the pipeline. [0004] A pipeline flowmeter provided by an embodiment of the present invention includes: a rotat...
