Description
Technical field
The utility model is related to technology, more particularly to a kind of technology of filling electromagnetic flowmeter.
Background technology
The filling production lines of beverage processing plant are required for the installation quality flowmeter on every liquid material flow in pipes, with
Just the amount of the liquid material of injection is monitored.There is volume is big and the defects of hardware cost is high for these mass flowmenters.Due to filling
Filling time on assembling production lines is short, and volume requirement consistency and required precision are high, and the reaction speed of flowmeter is required to compare
Height needs the rapid return data of flowmeter energy to automatic filling control system, timely to switch shutoff valve.And existing electromagnetic current
Gauge is although small, and hardware cost is low, but due to can not precisely be measured to short time instantaneous flow change dramatically,
Also it can not apply on the liquid material flow in pipes of filling production lines.
Utility model content
Defect present in for the above-mentioned prior art, the technical problem to be solved by the utility model is to provide a kind of energy
The precisely filling electromagnetic flowmeter of metering instantaneous flow variation in short-term.
In order to solve the above-mentioned technical problem, a kind of filling electromagnetic flowmeter provided by the utility model, including measurement pipe,
And the converter case in measurement pipe, the flow signal converter in converter case, it is characterised in that：
Yoke is fixed in the measurement pipe, fixes cored, diversion pipe in yoke, on iron core there are two symmetrical windings
Magnet exciting coil, the tube chamber of diversion pipe are connected with the tube chamber of measurement pipe, and measurement pipe caliber is the 2 times or more of diversion pipe caliber,
The symmetrical fixed measuring electrode there are two for measuring its intraluminal fluid flow on diversion pipe, and two measuring electrodes
The central axis of central axis and diversion pipe is mutually perpendicular to.
Filling electromagnetic flowmeter provided by the utility model, will be in the measurement pipe of Large Diameter Pipeline using the diversion pipe of pipe with small pipe diameter
Fluid is directed to measuring electrode position, can precisely measure instantaneous flow variation, and the central axis of two measuring electrodes in short-term
It is mutually perpendicular to the central axis of diversion pipe, yoke forms a closed magnetic circuit with two measuring electrodes, two magnet exciting coils, together
When can shield external magnetic field interference, can apply on the liquid material flow in pipes of filling production lines.
Description of the drawings
Fig. 1 is the structure diagram of the filling electromagnetic flowmeter of the utility model embodiment.
Specific embodiment
The embodiment of the utility model is described in further detail below in conjunction with description of the drawings, but the present embodiment and is not had to
In limitation the utility model, every similar structure using the utility model and its similar variation should all be included in the utility model
Protection domain, the pause mark in the utility model represents the relationship of sum.
As shown in Figure 1, a kind of filling electromagnetic flowmeter that the utility model embodiment is provided, including measurement pipe 1 and peace
Converter case 2 in measurement pipe, the flow signal converter 3 in converter case, it is characterised in that：
Yoke 7 is fixed in the measurement pipe, cored 6, diversion pipe 4 is fixed in yoke, is symmetrically arranged on iron core
Two magnet exciting coils 5, the tube chamber of diversion pipe are connected with the tube chamber of measurement pipe, and measurement pipe caliber is 2 times of diversion pipe caliber
More than, the symmetrically fixed measuring electrode 8 there are two for measuring its intraluminal fluid flow, and two measurements on diversion pipe
The central axis of electrode and the central axis of diversion pipe are mutually perpendicular to, and yoke is formed with two measuring electrodes, two magnet exciting coils
One closed magnetic circuit, while external magnetic field interference can be shielded.
In the utility model embodiment, the diversion pipe is stainless steel, and the inner wall of diversion pipe has to be molded by PFA
The lining of type can meet foodstuff sanitation-stage requirement, can measure the encapsulation of the liquid conducting medium such as mineral water, beverage, right
Moment big flow can be measured accurately in short-term, and error is within 0.3%.
