What kind of electromagnetic flowmeter is used for measuring acidity and alkalinity, and must be acid and alkali resistant to use?
It is necessary to check the specific composition of the medium on the fiber wheel. If possible, an on-site investigation can be conducted to ensure safety during use. Acid and alkali are harmful to the body. Improper selection of flow meters not only affects their service life but also brings trouble to maintenance.. The lining of the electromagnetic flowmeter can be made of PO material. In addition to strong oxidizing acids such as concentrated nitric acid, fuming sulfuric acid, and chlorosulfonic acid, it can withstand most organic and inorganic acids, bases, and salts, and has good resistance to stress corrosion. At 70C, it can withstand nitric acid, formic acid, acetic acid below 10%, hydrochloric acid below 30%, hydrobromic acid below 20%, dilute hydrofluoric acid, various concentrations of carbonic acid, boric acid, butyric acid, bases, and the vast majority of salts.
2. How to choose the material of electromagnetic flowmeter?
Tianjin Xuner Instrument answers for you: As a commonly used flow measurement instrument, the selection of material for electromagnetic flowmeter is also an important factor. Due to the fact that only the electrode and the interior of the measuring tube are in contact with the medium in the electromagnetic flowmeter, it is necessary to select the correct electrode and lining material according to the characteristics of different media.
1. Selection of electrode materials 1 Stainless steel (0Cr18Ni12Mo2Ti). Suitable for nitric acid, sulfuric acid with less than 5% at room temperature, boiling phosphoric acid, formic acid, al
2. Selection of lining material 1 Rubber. It has excellent elasticity, high tensile strength, good wear resistance, and resistance to general weak acids and alkalis. It can be used to measure water, sewage, mud, and slurry. 2. Polyamide. Coal slurry, mud and slurry with excellent wear resistance, poor acid and alkali resistance, and the ability to measure neutral and strong wear. 3. Polytetrafluoroethylene. Boiling resistant hydrochloric acid, sulfuric acid, nitric acid, aqua regia, concentrated alkali, and various organic solvents have good wear resistance but poor adhesion. The above is about the selection of materials for electromagnetic flow meters. Different media have different characteristics, and it is not necessary to choose the most expensive one. Choosing the appropriate one is the most economical and durable. Phone: Please accept if satisfied!
3. Selection reference for electromagnetic flowmeter electrodes under different fluid media
The selection of electromagnetic flowmeter electrodes should be comprehensively selected based on the corrosiveness, wear resistance, and working conditions of the f
