Electromagnetic flowmeter is widely in use in the production life flowmeter types, along with the progress of the instrument production technology, the electromagnetic flowmeter measurement technique and measurement accuracy and stability are also constantly improve, according to relevant data, the electromagnetic flowmeter market share increased year by year in the instrumentation industry, has become the main force in the field of flow measurement instrument type.
Product advantages of electromagnetic flowmeter in numerous flowmeter is very significant, especially in wastewater treatment, chemical production and other industrial fields has been widely used, the effect is remarkable, according to the summary of the our company technical personnel, has the following ten, users can according to the working conditions of the company in the production of reference to choose them.
1, the electromagnetic flowmeter measurement scale is big, usually for those days ~ 50:1, optional flow wide scale.
The full value of the liquid flow rate at 0.
Selected within 5 ~ 10 m/s.
Some models at the scene according to the need to expand and the instrument can reduce the flow (
For example, has four digits potentiometer setting instrument constant)
Don't take low offline real flow calibration.
2, electromagnetic flow meter
diameter size than the rest of the flow meters wide, from a few millimeters to 3 m.
Measurable positive and negative two-way flow, can also be pulsating flow measurement, only the pulsating frequency is lower than a lot of excitation frequency.
The instrument input is essentially linear.
Easy choice of contact with the fluid material, can be used in corrosive fluid.
3, electromagnetic flowmeter measurement channels is a shine a lubrication of straight pipe flow detection, because of not easy to block the practical for measuring containing solid particles or fibers of solid-liquid two-phase fluid, such as pulp, coal water slurry, pulp, mud and water, etc.
4, electromagnetic flowmeter does not occur for testing flow caused by pressure loss, the resistance of the meter is just the same along the length of pipe resistance and energy saving effects obvious, on request low resistance loss of large diameter water pipes as appropriate.
5, no mechanical inertial electromagnetic flowmeter, responsive, can measure the instantaneous pulse flow, also can measure the rate of flow of positive and negative two directions.
6, the electromagnetic flowmeter is due to the induced voltage signal is formed in the whole space full of magnetic field, is the average of the pipeline on the surface of the load, the amount of straight pipe required sensor is shorter, length of 5 times the pipe diameter.
7, the electromagnetic flowmeter is in measuring the pipe flow, so there is no additional pressure loss;
Measurement of the pipe have no moving parts, so very long sensor life.
8, electromagnetic flowmeter sensor structure is simple, the measuring tube has no moving parts, no obstacles to fluid flow throttling components.
So when the fluid flow through timing does not cause any additional pressure loss, is one of the flow meter flow meter running in low energy consumption.
9, volume flow rate measured by electromagnetic flowmeter, in practice from the fluid density, viscosity, temperature, pressure and conductivity (
Only above a certain threshold)
The influence of change significantly.
Compared with the rest of the big local flow meter, front straight pipe section of the request is low.
10 and measurable smudges medium, corrosive medium and clouding the liquid-solid two phase flow of traffic.
This is due to internal unimpeded flow meter tube parts, and the measurement of body contact is sounding pipe lining and electrode, the materials can choose according to the nature of the current body.
For example, made from poly three fluoride or ptfe lining, can measure all kinds of acid, alkali, salt and other corrosive medium.
Adopt wear-resisting rubber lining, is especially suitable for measuring with solid particle slurry, water slurry, wear a large liquid-solid two phase flow and various liquid with fiber and pulp suspension.
