1. Operation Principle

<>The operation of a magnetic flowmeter or mag meter is based upon Faraday's Law, which states

that the voltage induced across any conductor as it moves at right angles through a magnetic field is

proportional to the velocity of that conductor.

Faraday's Formula:

E is proportional to V x B x D where:

E = The voltage generated in a conductor

V = The velocity of the conductor

B = The magnetic field strength

D = The length of the conductor

To apply this principle to flow measurement with a magnetic flowmeter, it is necessary first to state

that the fluid being measured must be electrically conductive for the Faraday principle to apply. As

applied to the design of magnetic flowmeters, Faraday's Law indicates that signal voltage (E) is

dependent on the average liquid velocity (V) the magnetic field strength (B) and the length of the

conductor (D) (which in this instance is the distance between the electrodes).In the case of

wafer-style magnetic flowmeters, a magnetic field is established throughout the entire cross-section

of the flow tube (Figure 1). If this magnetic field is considered as the measuring element of the

magnetic flowmeter, it can be seen that the measuring element is exposed to the hydraulic

conditions throughout the entire cross-section of the flowmeter. With insertion-style flowmeters, the

magnetic field radiates outward from the inserted probe (Figure 2).

2. Main Features and Applications

Electromagnetic flowmeter consists of two parts of the sensor and transmitter. KF700-type

electromagnetic flowmeter for measuring a variety of acid, alkali, salt solution, paper pulp, slurry and

other conductive liquid or liquid-solid two-phase medium volume flow. In the chemical, alloy, water

supply and drainage, sewage treatment, food, sugar, paper making, environmental protection and

other departments to be widely application.

Criteria and process pipe welding flange screw holes in the inter-position, bolt can be passed smoothly to facilitate the integration between the sensor and process piping. Installation must ensure that sensors Center and the process pipe center line, and then a good grounding line, otherwise it would cause measurement error.

According to the work of instrument characteristics and technical characteristics, the choice of instrument installation environment should pay attention to: (1) The instrument should be installed at the ventilation to dry, avoid installing at the place easy accumulation water. (2) The instrument should try to avoid just sun shine and rain. Open-air installation, should keep out rain in places; (3) Installation of places as much as possible to avoid strong vibration; (4) as far as possible to avoid a strong electromagnetic field equipment; such as large motors, large transformers. (5) Select the ease of maintenance, activities, convenient place.

Installed on the sensor in the pipeline, we should note the following points (1) sign the direction of the flow sensors and pipeline flows in the same direction within the medium; (2) The need to ensure that sensor tube is full filled with the measured medium; (3) The sensors should be five times the upstream straight pipe section D above, the sensor should be three times the downstream straight pipe section D above (available from the center of sensor , D to measure the pipe diameter);

Remarks

The flow sensor generated signal by is very small, when in full-scale only a few mV, so the

sensor should be well grounded, in a good grounding line access must be in accordance with

the ninth Page shown

1）From the working principle of electromagnetic flowmeter and flow sensor signals to the circuit analysis,

sensors and ground-side converter must be consistent with the measured medium equipotential.

2）Grounding to the earth is zero potential to reduce outside interference. Under normal circumstances,

industrial pipes are metal tubes and grounded in itself, which easily meet the requirements, but in a larger

external electromagnetic field interference, the electromagnetic flowmeter grounding devices should be set up

for other way, with grounding line is greater than the total cross-section 6mm 'multi-strand copper wire, the

grounding line of sensors cannot be received in the motor or other equipment to the public online in order to

avoid the effects of leakage current. Grounding resistance should be less than 10.

3）Sensor is installed in the plastic pipe lines or in the pipe insulation, the sensor should be installed at both

ends of the grounding ring or grounding flange, or with a ground electrode a short tube, shown in figure 7.

4）Sensor be installed on the Catholic protection of pipelines, it must be installed two ends of grounding ring

(or grounding flange) on the sensors.Figure 8
