Abstract: the intelligent electromagnetic
flowmeter scale application in sewage treatment industry information produced by excellent flow meter, flow meter manufacturer to offer you the quotation.
Intelligent electromagnetic flowmeter application has more than 50 years of history, has been widely used in the global scope, field water/sewage, chemical, pharmaceutical, paper making, food and other industries.
Large diameter instrument is more applied in water supply and drainage engineering.
Small and medium caliber is often used to.
More flow meter manufacturers choose model price quote you are welcome to inquire, here is the intelligent electromagnetic flowmeter scale application in sewage treatment industry article details.
Intelligent electromagnetic flowmeter application has more than 50 years of history, has been widely used in the global scope, field water/sewage, chemical, pharmaceutical, paper making, food and other industries.
Large diameter instrument is more applied in water supply and drainage engineering.
Small and medium caliber is often used in solid-liquid two equal several fluid or high demand.
Small diameter, small diameter is often used in the pharmaceutical industry, food industry, biological engineering, etc have health requirements.
With the acceleration of China's industrialization, environmental pollution is increasingly serious, society of sustainable development is becoming more and more high, the concept of harmonious coexistence between man and nature to accept by people, to all sorts of pollution of more urgent.
A water treatment company in zhejiang and the city of printing and dyeing industry wastewater comprehensive sewage treatment enterprises, built one, the second phase of the project has reached 700000 tons/day sewage treatment capacity.
Because in the wastewater treatment process, need to discharge measure and control, additives, such as sludge, so the flow measurement is very important.
1.
The working principle of measuring principle of the intelligent electromagnetic flowmeter is based on Faraday's law of electromagnetic induction.
When the conductive metal rod with a certain speed in vertical direction of the magnetic field lines exercise, the induced voltage is produced.
If the magnetic field strength for B, metal rod of length L, velocity v, in the intelligent electromagnetic flowmeter, the measuring tube conductive medium is equivalent to conducting metal rods in the Faraday experiment, up and down at the ends of the two electromagnetic coils generate constant magnetic field.
When conducting medium flows, the induced voltage is produced.
The inside of the pipe induced voltage produced two electrodes are measured.
Measuring pipeline through non-conductive lining (
Rubber, teflon, etc. )
With fluid and measuring electrode electromagnetic isolation.
Assume that electromagnetic induction coil magnetic field intensity (
B）
As the constant, the induced voltage (
Ue）
Is proportional to the fluid velocity (
v）
, the pipe sectional area (
一)
As known, the volume flow (
Qv）
Can be calculated by the following formula: intelligent electromagnetic flowmeter is made up of flow sensor and transmitter of two parts.
Sensor tube fitted with excitation coil, excitation current to produce magnetic field through the measuring tube, a pair of electrodes in measuring tube wall in contact with the liquid phase, which leads to the induction electric potential, sent to the transmitter.
The excitation current was provided by the transmitter.
Classification in the converter and the sensor assembly way, has two kinds of separation type and size.
In the sewage treatment technology of large diameter flowmeter are separation, part is installed on the ground, the other part on the ground.
Small diameter with one-piece.
The function of the intelligent electromagnetic flowmeter on the market difference is very big also, simple just measure the one-way traffic, only after output analog signal to drive an instrument;
Multifunctional instrument with two-way flow measuring, switch range, upper and lower flow alarm, air traffic control and the power cut off alarm, cut of small signal, flow display and volume, automatic check and fault self-diagnosis, communicate with PC and motion configuration, etc.
Some models of instrument serial digital communication function can choose a variety of communication interface and dedicated chip (
ASIC)
To connect the HART protocol system, PROFTBUS, Modbus, FF fieldbus, etc.
The calibre of the intelligent electromagnetic flowmeter range than the other varieties of flow meter wide, golden lake gionee automation instrument with W, P, H, three types of sensor respectively applied in water and wastewater industry (
W)
, chemical industry, food industry,
P type)
, food, pharmaceutical industry (
H)
And diameter range from 2 mm to 2 m.
Transmitter can provide 10, 50, 23, 53, a variety of choices, 10 for water industry the development of economy, 50 as normal, 53 is enhanced, 23 for two wire system.
Precision can be 0.
5%, 0.
2% of two options.
Measurable positive and negative two-way flow, pulsating flow rate can be obtained.
Using intelligent electromagnetic flowmeter is the premise of measured liquid must be conductive and not lower than the threshold (
The lower limit value)
。
The , essentially perfected by v shape
coriolis mass flow meter, is one of the first home appliance to be widely distributed.
The 21st century is sure to bring more innovation, new services and newer technology, thus new products and services to sell. Beijing Sincerity Automatic Equipment Co., Ltd will continue to shape and lead the markets in which it chooses to compete.
You will have a
insertion ultrasonic flow meter that looks coriolis mass flow meter emerson all the time, Because your is handling with it.
We create a group of experts to promote the quality standard and innovative technology of
mass flow meter.
Beijing Sincerity Automatic Equipment Co., Ltd deems that we can drive consumer transactions using high-tech tools like artificial intelligence and cognitive data sets.
