How to choose the corrosive media flow meter

Corrosion of liquid with corrosion resistance, strong oxidant resistance associated with the flowmeter flowmeter, could the flow meter is used to measure or fluid mechanics total flow in open channel a dashboard, widely used in petroleum chemical industry, petroleum chemical industry equipment, sewage treatment, food industry, pharmaceutical industry, electric power, metallurgy industry, pulp paper industry and building decoration materials and other manufacturing industries.The following is a detailed explanation for different metrological verification media:

How to choose the corrosive media flow meter

I. measurement of acidic medium: the elliptic transmission gear flowmeter, vortex flow meter and the controller of pressurized total flow produced by the application of acid-resistant materials. The parts that touch the medium are all acid-resistant raw materials, which can withstand the general acidic chemicals, and can also be used to measure acidic medium.

Measure the corrosion vapor.The throttle valve type gas pressure flowmeter is generally used, lining the corrosion resistant raw material on the pipeline diaphragm.Diaphragm in the early application of corrosion of molybdenum stainless steel plate, after on the diaphragm seal on a layer of protective membrane ptfe, but still very easy to erosion, I companies constantly improve diaphragm material nature of the problem is still not processing, after the change with the spacer general dashboard with etching medium protection plan, application of the spacer fluorine oil is very expensive, greatly increased the dashboard of the product cost.

3. Make measurement plans according to the natural environment.Although some unique load is still not picked out the corrosion resistance of the flowmeter can solve the difficulties, at that time it is necessary to know deeper production process, choose to bypass traffic measurement instrument panel corrosion resistance of the difficulties, such as sewage treatment station traffic measurement, can consider to acid or alkali is added in the waste water in close before conducting metrological verification, to prevent the flowmeter from serious erosion.

The medium for measuring the conductivity.Can be used with the lining material corrosion - resistant electromagnetic induction flowmeter.

Measuring non-conductive media.It can choose the clamp-on ultrasonic flowmeter that does not touch with the medium, and can measure various strong acid and alkali etching medium.

Each company's commodity and application environment are different, so it is still necessary to choose the appropriate own flow meter according to the actual measurement medium and load standard.In addition to the quality of the dashboard itself to ensure that the production of processing information and the dashboard installation, application, maintenance is effective is also very critical.

Porcelain city of all flowmeters, small to a screw hole, large to the case and gear are using Germany Siemens CNC machining center to complete, completely get rid of the current domestic mechanical and manual mixing operation of the manufacturing process, elliptical gear manufacturing process will produce a milestone change.
