Product Description
Anti-Corrosion Explosion-Proof Electromagnetic Flowmeter For Hazardous Environments
The anti-corrosion and explosion-proof electromagnetic flowmeter is a specially designed pipeline electromagnetic flowmeter for measuring corrosive media and can operate safely in flammable and explosive hazardous environments.
Two key safety requirements: anti-corrosion and explosion-proof.
1. Anti-corrosion technology: material compatibility and structural protection
| Lining material | Resistant to pH range | Maximum temperature resistance | Applicable media | Limitations |
|---|---|---|---|---|
| PFA (Perfluoroalkoxy resin) | pH 0-14 (strong acids, strong bases, organic solvents) | 260℃ | Sulfuric acid, sodium hydroxide | Weak wear resistance, be cautious when solid content > 5% |
| PTFE (Polytetrafluoroethylene) | pH 0-14 (resistant to strong corrosion, non-stick to media) | 250℃ | Fluorine acid, aqua regia, concentrated nitric acid | Insulation slightly decreases at high temperatures (> 200℃) |
| Ceramic (Al₂O₃) | Resistant to acids and alkalis, wear-resistant, oxidation-resistant | 1800℃ | Corrosive media with high solid content (such as slurry, salt slurry) | Brittle, avoid severe impact |
| Polyurethane rubber | Resistant to weak acids and alkalis, highly wear-resistant | 80℃ | Seawater, slurry, weak acids and alkalis |
2. Explosion-proof Technology: Dual Assurance of Structure and Certification
| Explosion-proof Type | Structural Principle | Explosion-proof Grade (Typical) | Aplicable Environment |
|---|---|---|---|
| Flameproof Type (Ex d) | Outer casing withstands internal explosion pressure to prevent flame leakage | Ex d IIC T6 | Chemical workshops, petrochemical plant areas (Class II C gases such as hydrogen and acetylene) |
| Intrinsically Safe Type (Ex ia) | Limit circuit energy to prevent ignition of explosive mixtures | Ex ia IIC T4 | Instrument control rooms, internal junction boxes in explosion-proof areas |
| Increased Safety Type (Ex e) | Optimize structural design to reduce ignition risk | Ex e IIB T5 | Non-direct explosion zones (such as auxiliary workshops in petrochemical plants) |
| Dust Explosion-proof Type (Ex tD) | Prevent dust from entering the casing to avoid explosion | Ex tD A21 T135℃ | Flour mills, chemical dust workshops |
Application scenarios
- This flowmeter is the ultimate guarantee of safety and durability, mainly used in the following high-risk industries:
- Chemical industry: Measuring highly corrosive chemicals such as hydrochloric acid, sulfuric acid, and caustic soda (NaOH), where flammable and explosive gases are often present in the production site.
- Petroleum and natural gas: Measuring sulfur-containing crude oil, acidic oil-gas-water mixtures, and environments with methane, gasoline vapor, etc.
- Pesticide: Measuring various organic solvents, reaction intermediates, etc. in explosion-proof workshops.
- Coatings and dyes: Measuring flammable and explosive coatings, resins, solvents, etc.
- Mining and metallurgy: Measuring corrosive mine pulp, flotation agents, and environments that may contain flammable dust.
The anti-corrosion and explosion-proof electromagnetic flowmeter is a high-tech and highly specialized instrument. Its core features are as follows:
- Anti-corrosion: It achieves resistance to corrosive media through special inner linings and electrode materials.
- Explosion-proof: It adopts special structural designs such as flameproof and intrinsically safe, and has been certified by authoritative institutions to ensure absolute safety in hazardous environments.
When making a selection, it is essential to provide detailed working conditions and choose qualified products with corresponding explosion-proof certification certificates to ensure the safety, reliability, and compliance of the entire measurement system.
