Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electromagnetic flow measurement, in particular to a flow measurement device for electromagnetic flow velocity. Background Art
[0002] As we all know, a flow meter is an instrument used to indicate the measured flow rate in a pipeline and / or the total amount of fluid in a specified time interval; that is, an instrument used to measure the flow rate of fluid in a pipeline. There are many types of flow meters, which are divided into differential pressure flow meters, rotor flow meters, electromagnetic flow meters, and ultrasonic flow meters according to their structures or uses.
[0003] Traditional electromagnetic flow meters generally include a monitoring body and an electromagnetic flow tube located in the water. The flow is measured by the flow rate in the electromagnetic flow tube. However, since most of the floating objects in the water are leaves, roots, or other small pieces of floating garbage, these floating objects are easy to accumulate on the port of the electromagnetic flow tube when passing through the electromagnetic flow tube. Over a long period of time, the accumulation will increase, which can easily cause the water flow entering the electromagnetic flow tube to become smaller, affecting the quality of monitoring.
