Problems solved by technology

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a plug-in probe for electromagnetic flowmeters, which solves the problem that the outer diameters of the probe and the insertion rod are not consistent in the prior art, and the connection position between the probe and the insertion rod is formed. The concave-convex surface increases the influence of velocity distribution distortion, and the problem that the traditional electrode setting is easily damaged during the installation process in the middle of the probe

Embodiment Construction

[0016] The specific implementation will be described in further detail below in conjunction with the accompanying drawings.

[0017] Shell 1: The shell 1 is a cylinder supported by PVDF material. The shell 1 is directly processed and formed by using PVDF rods during processing, which has good high temperature resistance and corrosion resistance. The shell 1 The diameter of one end of one end is reduced to form a connection part connected with the insertion rod, the connection part and the insertion rod are provided with a detachable connection structure, the connection part is provided with external threads, and the insertion rod and the shell The connection part of the body 1 is threaded, the outer diameter of the insertion rod is consistent with the outer diameter of the housing 1, and the insertion rod and the housing 1 will not form a concave-convex surface, which effectively reduces the measurement Influenced by the distortion of velocity distribution during the process, ...

Abstract

The invention discloses a plug-in type probe used for an electromagnetic flowmeter and belongs to the field of liquid flow measurement. The plug-in type probe comprises a cylindrical shell; an electric signal generating component, arranged at the interior of the shell, comprises a coil component, a pole shoe, a magnetic yoke and a plurality of electrode cables; a connecting part used for connecting an insertion rod is arranged at one end of the shell; a detachable connecting structure is separately arranged at the connecting part and the insertion rod; the outer diameter of the insertion rod is same as that of the shell; a choke plug is connected at the other end of the shell; two electrode components are arranged at the end face of the choke plug; and the two electrode components are provided with current guiders used for guiding current. The plug-in type probe used for an electromagnetic flowmeter solves the problems in the prior art that the outer diameter of the probe is inconsistent with that of the insertion rod, the concave-convex surface formed at the connecting position of the probe and the insertion rod increases the speed distribution distortion influences and the traditional electrodes arranged in the middle of the probe are easy to damage in the installation process.

Description

technical field [0001] The invention relates to the measurement field of liquid flow, in particular to an insertion probe for electromagnetic flowmeter. Background technique [0002] For the measurement of large pipe diameter flow, the flow field is relatively stable, and the flow velocity distribution in the closed pipe is relatively regular and axisymmetric in the measurement section. Insertion electromagnetic flowmeters can be used for flow measurement. Plug-in electromagnetic flowmeter is a flowmeter instrument. The measurement principle is the same as that of electromagnetic flowmeter. The difference is that the plug-in electromagnetic flowmeter is composed of an insertion rod and a detection probe. The detection probe is directly inserted into the fluid to measure the point flow velocity of the fluid on behalf of the pipeline. the average flow rate. The general insertion depth is 1 / 8 of the pipe. Because this point is usually the average flow velocity point of the fl...
