Abstract

A magnetic yoke type plug-in electromagnetic flowmeter is mainly a sensor connected with a converter, and is composed of an insertion rod and a probe connected with the insertion rod and connected with an electrode, wherein a magnetic yoke is arranged on an excitation coil of the probe. The magnetic field intensity can be greatly increased, and the accuracy of the plug-in electromagnetic flowmeter for measuring the volume flow of various conductive liquids in the pipeline can be greatly improved through the Faraday's law of electromagnetic induction.

Description

Insert type electromagnetic flowmeter with magnetic yoke
Technical Field
The utility model relates to a flowmeter, especially take bayonet electromagnetic flowmeter of yoke formula. It is suitable for measuring the volume flow of various conductive liquids in the pipeline.
Background
The working principle of the plug-in electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. The plug-in electromagnetic flowmeter is formed by matching a converter and a sensor and is used for measuring the volume flow of various conductive liquids in a pipeline. Most of the flow meters have low accuracy and instability in measuring the volume flow of various conductive liquids in pipelines.
Disclosure of Invention
An object of the utility model is to provide a bayonet electromagnetic flowmeter of band yoke formula, it can overcome the not enough of prior art, can increase magnetic field intensity effectively, through Faraday's electromagnetic induction law, can improve electromagnetic flowmeter measuring degree of accuracy and stability widely.
The solution is as follows: the magnetic yoke type plug-in electromagnetic flowmeter consists of a converter and a sensor connected with the converter, the sensor consists of an insertion rod and a probe connected with the insertion rod and connected with an electrode, and a magnetic yoke is arranged on an excitation coil of the probe.
The above technical scheme is adopted in the utility model, owing to be equipped with the yoke on sensor probe's excitation coil, but increase magnetic field intensity widely, through Faraday's electromagnetic induction law, can improve the measuring accuracy degree of volume flow of bayonet electromagnetic flowmeter to various conductive liquid in the pipeline greatly. The plug-in electromagnetic flowmeter can be mounted and dismounted under the condition of no current interruption, so that convenience is brought to the overhaul of a user; compared with the common electromagnetic flowmeter, the electromagnetic flowmeter has lower manufacturing cost and installation cost, and is particularly suitable for measuring the flow of large and medium-diameter pipelines.
Drawings
Fig. 1 is a schematic structural view of a yoke-equipped plug-in electromagnetic flowmeter.
Fig. 2 is an enlarged sectional view taken along line a-a in fig. 1.
Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
In fig. 1 and 2, the sensor is composed of a plunger 3 and a probe 4 connected thereto. The probe 4 is composed of a coil skeleton 6 and an excitation coil 7 connected with the coil skeleton, and a magnet yoke 8 is wound on the excitation coil 7. The probe 4 is connected to an electrode 5. The plunger 3 of the sensor is connected to the transducer 1 via a connecting fixture. And a valve assembly 2 is connected to the insertion rod 3 of the sensor.
When the device works, the sensor probe 4 is inserted into the central position of a user pipeline, when a conductive medium flows through, induced voltage is generated, induced voltage signals are detected by the electrodes 5 which are in direct contact with liquid on two sides of the probe 4 and are transmitted to the converter 1 through the cable, the signals are output after being converted by the converter 1, and the measured liquid flow data of the conductive medium can be obtained.
When the plug-in electromagnetic flowmeter is mounted and dismounted without interrupting the flow, the liquid overflow in the pipeline can be controlled by operating the valve component 2.
