Abstract

The invention discloses a flow measuring device and method. When a main pipeline and a pump arranged on the main pipeline are immersed in a liquid medium and work, a branch pipe which is communicatedwith the main pipeline and has the inner diameter smaller than that of the main pipeline is arranged and connected to the wall face, close to an output port of the pump, of the main pipeline, an overflow pipe which is immersed in the liquid medium is connected to an outlet of the branch pipe, a flowmeter is arranged on the overflow pipe, and the overflow pipe flow value which is actually measuredby the flowmeter is converted into the main pipeline flow value in the main pipeline. According to the flow measuring device and method, the flowmeter can be convenient to maintain and replace, the main pipeline does not need to be cut off, continuous normal conveying of the main pipeline can be guaranteed, normal work is not influenced, and the flow measuring device and method are suitable for situations in which the pump and the main pipeline need to continuously work for a long term.

Description

technical field [0001] The invention relates to the technical field of flow measurement, in particular to a flow measurement device and method. Background technique [0002] The common way to measure the flow rate of the liquid medium conveyed in the pipeline is to measure the flowmeter in series in the pipeline matching the diameter of the pipeline. The commonly used flowmeters include electromagnetic flowmeter, ultrasonic flowmeter, vortex flowmeter, differential pressure type flowmeter, turbine flowmeter, etc. When the pump and the pipeline are fixedly submerged in the liquid medium, the installation and removal of the flowmeter connected in series in the pipeline is very inconvenient. When the flowmeter breaks down and needs to be repaired, maintained or replaced, the pipeline must be interrupted first. The normal transportation of the flowmeter can only be maintained and replaced before the flowmeter can be maintained. Therefore, the overhaul and maintenance of the flo...
