Electromagnetic flowmeter shell material: carbon steel, 304, 316L stainless steel.
Electromagnetic flowmeter electrode materials: stainless steel 316L; Hastelloy B; Hastelloy C; platinum; tantalum; titanium
Good corrosion resistance: stainless steel shell can resist the erosion of various chemical substances, suitable for measuring the electromagnetic flowmeter of various fluids in the general industrial environment. For example, in the chemical industry, food processing, water treatment and other industries, may come into contact with a certain degree of corrosive fluids, stainless steel shell can prevent the shell from being corroded, thus extending the service life of the electromagnetic flowmeter.
High strength: Stainless steel has high mechanical strength, which can provide effective protection for internal components such as sensors and transducers. In some applications that may be subject to mechanical shock or under certain pressure, such as dense areas of industrial piping or flowmeter outdoor installation, stainless steel shell can protect the internal components from damage.
Electromagnetic shielding performance: stainless steel shell on the electromagnetic field has a certain shielding effect, can reduce the external electromagnetic field on the flowmeter internal electromagnetic induction process of interference, but also to prevent the internal magnetic field on the interference of external equipment. This is very important to ensure the measurement accuracy of electromagnetic flowmeter, especially in the presence of a large number of electrical equipment in the industrial environment.

In general industrial environments, carbon steel housing can meet the basic protection requirements of electromagnetic flowmeter. Carbon steel has high strength and hardness, and the price is relatively cheap, it is a more economical choice.
Carbon steel shell electromagnetic flowmeter corrosion resistance is poor, easy to rust and corrosion, especially in the humid corrosive media environment. Additional anti-corrosion treatment is required, such as painting and galvanizing, which will increase maintenance costs and workload. In addition, the weight of carbon steel is relatively large, which will bring some inconvenience to the installation and transportation.
The liner must be chemical-resistant, non-conductive, and durable:
| Liner Material | Features | Applications |
|---|---|---|
| PTFE (Polytetrafluoroethylene) | High chemical resistance, temperature-resistant up to 180°C | Chemicals, acids, high-temperature liquids |
| PFA (Perfluoroalkoxy alkane) | Similar to PTFE but with better mechanical strength | Aggressive chemicals, pharmaceutical applications |
| Rubber (Hard & Soft Rubber, Neoprene, EPDM, NBR, Natural Rubber) | Good for general water, wastewater, and slurry applications | Drinking water, wastewater, mining slurries |
| Ceramic | Extreme wear resistance, high temperature and pressure resistance | Abrasive fluids, mining, and high-pressure applications |
The electrode material should be corrosion-resistant and conductive:
| Electrode Material | Features | Applications |
|---|---|---|
| 316L Stainless Steel | Standard, corrosion-resistant | Clean water, food & beverage |
| Hastelloy C | Highly corrosion-resistant | Acidic and oxidizing fluids, chemical industry |
| Titanium (Ti) | Excellent resistance to seawater and certain chemicals | Seawater, chloride-containing solutions |
| Tantalum (Ta) | High resistance to strong acids (e.g., sulfuric, hydrochloric) | Chemical processing, strong acids |
| Platinum (Pt) | High chemical and temperature resistance | Specialty applications, high-cost environments |
