Product description:

JC-LGD series electroplating wastewater flow meter

Electroplating wastewater flow meter Is an electromagnetic induction type flow meter, which consists of sensors and intelligent signal converter. It can measure the volume flow of various types of conductive liquid, the measured media including acids, bases, salts and other corrosive liquids, raw water, cooling water , pulp, mud, coal slurry, pulp, molasses, corn syrup, fiber pulp, grain syrup, lime, hydrogen peroxide, water, beer, wort, milk and a variety of beverages such as conductive liquid and solid-liquid two-phase liquid. The product Mainly used Petrochemical, steel, power, metallurgy, textile, food, pharmaceutical, paper and other industries and municipal environmental protection, water And other fields.

Electroplating wastewater flow meter Yes Faraday's law to work on the measurement pipe axis and the magnetic field lines perpendicular to the wall to install a pair of sensing electrodes, when the conductive liquid along the pipe axis flow, conductive liquid cutting magnetic field lines generated EMF based on this sensor the potential detected by the two detection electrodes, the value proportional to the size of the flow, which is calculated as:
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.
Third, the product features:
Electroplating wastewater flow meter has the following characteristics:
1, no moving parts inside the pipe, unimpeded flow of parts, measuring almost no additional pressure loss;
2, the measurement results with the velocity distribution, physical parameters of fluid pressure, temperature, density, viscosity and the like;
3, in the field online range according to actual needs of users;
4, programmable low-frequency square wave excitation frequency and improve the stability of flow measurement, low power loss;
5, using new ultra-low-power 16-bit microprocessor containing flash memory, high integration, fast speed, high accuracy;
6, low EM1 switching power supply for power supply voltage range, strong anti-electromagnetic interference capability;
7, high-resolution backlit LCD display wide temperature range, Chinese and English menu operation, easy to use, simple to operate, easy to understand;
8, all-digital processing, anti-interference ability, reliable measurement, high accuracy flow measurement range of up to 150: 1;
9, has three internal totalizer, show positive cumulative reverse the cumulative amount and the difference between the volume totalizer, convenient fluid metering and trade settlement;
10, with RS485 digital communications signal output, optional RS232 and HART and other fieldbus digital communication output (optional);
11, has cleared totalizer remote control functions, with open and stop the cumulative contact signal input, suitable for total inspection and batch processing applications;
12, a self-test and self-diagnostic function, it is determined enough electrodes are contaminated, coverage and other anomalies, to provide users with information processing such as cleaning fault electrode;
13, the interior design of the instrument does not power down the clock, it can record power-down time (optional);
14, with optional hour meter total recording function, traffic data can be stored for more than 30 days of history.
