24VDC Powered Wasted Water Treatment Sewage Customized Electromagnetic Flow Meter MFE600C
Features:
• The special structure of the insert flowmeter can be easily installed and disassembled under the condition of low pressure and non-stop water. Therefore, it is very suitable for fluid measurement of existing pipelines and facilitates the maintenance and repair of instruments;
• Adopt advanced low frequency square wave excitation. The zero point is stable, the anti-interference ability is strong, and the work is reliable;
• Compared with the general electromagnetic flowmeter, the manufacturing cost and installation cost are lower;
• Two-way measurement system can measure forward flow and reverse flow; low frequency rectangular wave excitation improves flow stability, low power loss, and excellent low flow rate characteristics.
Introduction
MFE600C Insert electromagnetic flowmeter is a new type of flow measuring instrument developed on the basis of pipeline electromagnetic flowmeter. On the basis of retaining the advantages of the pipeline electromagnetic flowmeter, the defects of difficult installation and high cost of the pipeline electromagnetic flowmeter on large pipelines are avoided. In particular, the method of opening under pressure and installation under pressure can be adopted, so that the plug-in flowmeter can be constructed and installed without stopping the water. It provides a new method for the measurement and installation of liquid flow. At present, it has been widely used in chemical industry, water supply and drainage, sewage treatment and other industries.
Working Principle
The working principle of Electromagnetic Flowmeter is based on Faraday's Law of Electromagnetic Induction, that is, when the conductive liquid flows through the electromagnetic flowmeter, the induced electromotive force will be produced in the liquid conductor, and the induced electromotive force is directly proportional to the velocity of conductive liquid, magnetic flux density and width of conductor (interior diameter of flowmeter). Such induced electromotive force is detected by a pair of electrodes on the tube wall of the flowmeter, and the equation of induced electromotive force is as follows: U = K×B×V×D U: Induced electromotive force K: Instrument Constant B: Magnetic flux density V: Velocity D: Interior diameter of measuring pipe
Measurement Range setting:
The volumetric flux is set by the setup of volume unit, flux value and diameter of flowmeter.

Velocity unit: M/s
Diameter of flowmeter: mm
Transient flux display: Display flux unit, and the percentage of range.
Integrated flux display: Display forward and reverse integrated flux and total integrated flux.
Pulse output: By setting an impulse ratio, the pulse quantity expressed in any flux unit can be output.
Pulse width: Duty ratio of 50% or fixed pulse width is available for users to choose.
Output speed: 10 to 400 (PPS) (only applicable when the form of pulse output is selected).
Black-out data protection: Data will be stored by EEPROM without backup battery.
Forward and Reverse flux measurement: In the model of forward and reverse flow direction, the reverse flux can be measured.
Upper limit alarm: The transient flux is larger than the upper limit of setting value
Lower limit alarm: The transient flux is smaller than the lower limit of setting value

Model Selection
The flowmeter model selection is very important in application of instrument. The related information shows that in practical application of instrument, 2/3 failures are caused by incorrect selection of model and incorrect installation of instrument to which the special attention shall be paid.
1. Technological data collection
A. The measured fluid name and its chemical substances
B. Maximum flux, minimum flux and normal flux
C. Maximum working pressure;
D. Maximum temperature, minimum temperature.
2. The measured liquid shall have certain conductivity, electrical conductivity ≥5μS/cm.
3. The maximum flux and the minimum flux shall meet the values in the measurable flux range table.
4. The actual maximum working pressure shall be less than the rated working pressure of flowmeter.
5. The maximum working temperature and the minimum working temperature shall meet the temperature requirements stipulated for flowmeter.
6. Whether negative pressure exists or not in the processing pipeline shall be confirmed.
You can also select the appropriate flowmeter electromagnetic flowmeter according to actual use, and if the interior diameter of the electromagnetic flowmeter selected differs from that of the existing process pipe, then pipe reduction or expansion shall be considered.
1. If the pipeline should be contracted, whether the pressure loss caused by the pipe contraction will affect the process flow or not shall be considered.
2. Considering the measurement accuracy and price, you can choose a smaller diameter electromagnetic flowmeter, which can reduce the investment relatively.
3. When measuring clean water, the economic velocity is 2m/s ~3m/s; When measuring the solution of crystallization, the velocity shall be increased approximately to common velocity of ≥2 m/s, in order to prevent the electrode of electromagnetic from flowmeter being covered.
