With industrial development now, the domestic for attaches great importance to environmental protection, industrial and resident life all need to do all kinds of waste disposal, industrial wastewater and domestic sewage quantity for big category, which is how to be more efficient to deal with sewage, the sewage discharge end and processing end for sewage requires accurate measurement, and eventually into a harmless sewage on how to do a quantity control, sewage, environmental governance and so on need to measure sewage flow measurement mentioned in the industrial production of the flowmeter
type many, such as electromagnetic flowmeter, orifice flowmeter, turbine flowmeter, etc. , exactly what kind of flow meter to measure the sewage is better, sewage electromagnetic flowmeter should choose what material?
Sewage electromagnetic flowmeter selection should be?
Currently widely used in industrial sewage flow meter is composed of electromagnetic flowmeter sensor and converter matching, measure the pipe of various conductive fluid or liquid solid two medium volume flow.
Sewage electromagnetic flowmeter was widely used in chemical industry, metallurgy, paper making, water conservancy, environmental protection, printing and dyeing, oil, coal and other industries, used to measure the sewage volume flow of conducting liquid medium.
Why did you choose the electromagnetic flow meter as the optimal choice of sewage flow measurement?
Sewage electromagnetic flowmeter is one aspect, the advantages of the instrument in the embellish technology engineering and technical personnel for your detailed introduction.
Electromagnetic flowmeter is a kind of electromagnetic flowmeter (
Electromagnetic Flowmeters, EMF)
Is 50 ~ 60 s of the 20th century has been developed rapidly with the development of electronic technology and the new type of flow measurement instrument.
Electromagnetic flowmeter is the basis of the principle of electromagnetic induction, according to the conductive fluid through additional magnetic field induced electromotive force to measure an instrument of conductive fluid flow.
This flowmeter for flow measurement is not affected by the fluid density, viscosity, temperature, pressure and conductivity changes, the influence of sensor induction voltage signal, and a linear relationship between the average flow, so the measurement precision is high.
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.
Due to the induced voltage signal is formed in the full of magnetic field in the middle of the, is therefore needed for the sensor on the surface of the pipe load average short straight pipe, the length of 5 times the pipe diameter.
Many kinds of electrode and the lining material, can meet the requirements of corrosion resistance, wear resistance.
HSBLDE converter USES the domestic new single chip microcomputer and surface-mount technology, reliable performance, high precision, low power consumption, zero point stability, easy parameters setting, click on the Chinese display, LCD display, cumulative flow instantaneous flow rate and flow velocity, flow percentage, etc.
Two-way measurement system, measured flow, reverse flow, the use of special production technology and materials, to ensure that the performance of the product in a long time remained stable.
Electromagnetic flowmeter features make the electromagnetic flow meter wide range of USES, use on the sewage flow measurement is * * * to choose, so at the time of measurement should be how to choose the sewage electromagnetic flowmeter types?
Electromagnetic flowmeter with IP67 protection grade (
Dust-proof and flooding level)
Or IP68 (
Dust-proof and diving level)
In the wastewater factory of large diameter flowmeter sensors are installed in underground, so we suggest IP68 (
Dust-proof and diving level)
Electromagnetic flow at the installation sites and generally has the following requirements: mixed phase flow measurement, choose the place that does not cause phase separation;
When measuring the two-component liquid, avoid in has not yet been mixing downstream;
When measuring chemical reaction, in response to fully complete the section downstream;
As far as possible to meet straight pipe respectively before and after not less than 5 d and 2 d;
As far as possible to avoid the measuring tube into a negative pressure;
Choose the little vibration, especially for a size instrument;
Avoid near a big motor, transformer, etc. , so as not to cause electromagnetic interference;
The place that is easy to realize sensor separate grounding;
As far as possible to avoid the environment has a high concentration of corrosive gas;
As far as possible to avoid the direct sunlight can be used for conventional display and measurement of fluid flow and trade settlement embellish instrument is a factory specializing in the production of flowmeter, * * technicians and senior experience for many years to build domestic well-known brand flow meter.
Electromagnetic flowmeter is embellish instrument in the dominant products, not just in terms of price advantage, in terms of quality, higher counterparts in service.
