Abstract
Description
technical field
[0001] The invention belongs to the technical field of intelligent ultrasonic flowmeters, in particular to a method and system for detecting blockage of ultrasonic flowmeters. Background technique
[0002] Existing ultrasonic flowmeters usually only have a metering function, and cannot detect blockage of the flowmeter in time. At present, related technologies related to flowmeter blockage, such as the Chinese patent "Container rectification, anti-blockage, small pressure loss, easy maintenance, ultrasonic flowmeter base meter" with publication number CN201707082U propose that transducers are installed on the top of the two ends of the pipe section shell. 1. A reflector bracket is vertically installed directly below the transducer. The pipe segment shell at the reflector bracket increases the internal space and the corresponding external dimensions. The internal space of the enlarged shell is equivalent to a "container", so that the line contained in the flow ...

Embodiment Construction
[0033] The preferred embodiments of the present invention will be described in detail below.
[0034] The present invention relies on monitoring sensors deployed within the flow meter.
[0035] An embodiment of the method for detecting blockage of an ultrasonic flowmeter of the present invention is characterized in that:
[0036] Obtain the pressure data and current flow data of the ultrasonic flowmeter. When the pressure data and the current flow data do not match, judge the ultrasonic flowmeter based on the pressure data and / or historical flow data of the ultrasonic flowmeter and / or the adjacent flowmeter data in the area Whether there is a blockage.
[0037] The specific description is as follows:
[0038] The judging whether the ultrasonic flowmeter is blocked according to the pressure data of the ultrasonic flowmeter and / or historical flow data and / or the data of adjacent flowmeters in the area includes: judging whether the ultrasonic flowmeter is blocked according to t...
