Abstract

The invention relates to asmall pipe diameter closed pipeline water flow ultrasonic measurement optimization method and device. The small pipe diameter closed pipeline water flow ultrasonic measurement optimization method is used for measuring the water flow of a pipeline under Z mounting method and comprises the step that two measuring probes of an ultrasonic flowmeter are fixed to the opposite sides of the pipeline using a U-shaped fixator so that the measuring probesareconnected with the surface of the pipeline in a coupling mode; the U-shaped fixator comprises bolts and nuts, the boltsareof U-shaped structures, and the tightness of the nutsis adjustable. The small pipe diameter closed pipeline water flow ultrasonic measurement optimization method and device have the following technical effects that fixing difficulty of ultrasonic flowmeter probesis reduced; accuracy of the ultrasonic flowmeter Z method is improved; and the flowmeter probesare convenient to mount, and time and labor are saved.

Description

technical field [0001] The invention belongs to the technical field of energy saving and water saving in industrial enterprises, and in particular relates to an ultrasonic measurement optimization method and device for water flow in a small-diameter closed pipeline. Background technique [0002] With the increasing shortage of water resources in our country and the improvement of environmental protection requirements, it is very important to actively promote and apply energy-saving and water-saving measures in industrial enterprises. water resources. [0003] Commonly used test methods for water volume testing include direct test method and indirect test method. Direct test methods include flow meter method, flow meter method, volumetric method, etc. Indirect test method is only used when the direct method cannot be tested due to its poor accuracy. At present, the flowmeters commonly used in the direct test method include water meters, differential pressure flowmeters, elec...
