Product description:

Jing Chuan JC-LDG / S integrated electromagnetic flowmeter
I. Product Overview:
Electromagnetic flowmeter converters and sensor assembly press can be divided into two categories: one-and-one split electromagnetic flowmeter Is the most widely used form of electromagnetic flowmeter, as shown in the following figure:
Jing Chuan JC- LDG / S Type-one Electromagnetic Flowmeter By the direct contact of media channels and the upper two-part sensor signal converter constituted. It is based on Faraday's law of electromagnetic induction Work for measuring Conductivity Flow conductive liquid is greater than 5μs / cm, which is a conductive medium flow measurement instruments. In addition to measuring the flow of conductive liquid, but also can be used to measure acid, alkali and other strong corrosive liquids and even contain liquid-solid suspension of liquid, such as mud, pulp, paper pulp, etc., it is widely used in chemical fiber, food, paper, sugar, mining, water supply, environmental protection, water conservancy, steel, petroleum, pharmaceutical and other industrial areas to measurement of various chemical salt solution, slurry, pulp, paper pulp, coal water slurry, corn syrup, fiber pulp, grain syrup, lime, sewage, cooling raw water, drainage, saline, hydrogen peroxide, beer, wort, drinks the flow of black liquor, green liquor and other conductive liquid medium.
Second, the principle:
Jing Chuan JC- LDG / S Type-one Electromagnetic Flowmeter It is based on Faraday's law of electromagnetic induction to work; in the measurement pipe axis and the magnetic field lines perpendicular to the wall of a pair of detecting electrodes installed; when the conductive liquid along the pipe axis flow; conductive liquid cutting magnetic field lines generated EMF; this EMF detected by the two detection electrodes; flow rate proportional to the numerical size; it is calculated as follows:
E = B * V * D * K
Where, E-- EMF;
K-- the magnetic field distribution and the axial length of the relevant factors;
B-- magnetic induction;
V-- conductive liquid average velocity;
D-- electrode spacing (pipe diameter);
E EMF sensor as a flow rate signal is transmitted to the converter, after the amplifier, transform, filter and a series of digital processing, with bright LCD display instantaneous flow rate and cumulative flow, converter has 4-20mA output, alarm output , frequency output can be selected, and a RS485 communication interface, and supports HART and MODBUS communication protocol.
