Produkt beskrivelse

Elektromagnetisk flowmeter er et flowmeter, der måler strømning baseret på Faradays lov om elektromagnetisk induktion. Fordelene ved elektromagnetisk flowmeter er et lille tryktab og et stort målbart flowområde. Forholdet mellem den maksimale strømningshastighed og minimumsstrømningshastigheden er generelt mere end 20: 1. Den bruger en lang række industrielle rørdiametre og kan måle rørdiametre i området af DN10 ~ DN2000. Udgangssignalet er lineært med den målte strømningshastighed. Det har høj nøjagtighed og kan måle ledningsevnen. Fluidstrømningshastighed på ≥5 μs/cm for syrer, alkalier, saltopløsninger, vand, spildevand, ætsende væsker, mudder, mineralmasse, papirmasse osv. Det er vidt brugt i flowmålermåling i kemisk industri, metallurgi, tekstil, papermaking , Miljøbeskyttelse, mad, indenlandsk spildevand, industrielt spildevand, kølevand, vandplanter og andre industrielle sektorer, såvel som inden for kommunel ledelse, vandforretningskonstruktion, flodudgravning, måling af vandforsyning og andre felter.

Produktegenskaber

1. Konverteringsdisplayet vedtager 16-bit højtydende mikroprocessor og 2 × 16LCD-display, hvilket gør parameterindstillingen let og programmering pålidelig.

2. Bidirectional Målesystem, udstyret med tre totalisatorer, der kan vise henholdsvis: fremadrettet flow, omvendt strømning og den samlede mængde af forskellen mellem fremad og omvendt strømning.

3. Konverteringsdisplayet har en række output: nuværende, puls, digital kommunikation, Hart, 485 kommunikationsprotokol.

4. Velegnet til rør med stor diameter, DN300-1400mm.

5. Sensorlegemet og elektroderne fås i forskellige materialer.

6. Lille størrelse, let vægt, let at transportere og installere og kan realisere kontinuerlig vedligeholdelse, demontering og montering.

Forvalgstabel

Lining material	Main performance	Maximum medium temperature		Scope of application
Lining material	Main performance	Integrated type	Separate type
Polytetrafluoroethylene (F4)	It is a kind of plastic with very stable chemical properties. It can withstand boiling hydrochloric acid, sulfuric acid, nitric acid and aqua regia, as well as concentrated alkali and various organic solvents. Not resistant to corrosion by chlorine trifluoride, high-temperature chlorine trifluoride, high-flow liquid fluorine, liquid oxygen, and auto-oxidation.	70℃	100℃ 250℃ (Special order required)	1. Strongly corrosive media such as concentrated acid and alkali. 2. Sanitary media.
Polyperfluoroethylene-propylene (F46)	Same as F4, but its wear resistance and negative pressure resistance are higher than F4.		Same as above
Polyfluoroethylene (Fs)	The upper limit of applicable temperature is lower than that of polytetrafluoroethylene, but the cost is also lower.		80℃
Polychloroprene	1. It has excellent elasticity, high tearing force and good wear resistance. 2. Resistant to the corrosion of general low-concentration acid, alkali and salt media, but not resistant to the corrosion of oxidizing media.		80℃ 120℃ (Special order required)	Water, sewage, weakly abrasive mud or slurry.
polyurethane rubber	Extremely wear-resistant.		80℃	Neutral strong abrasion slurry, coal slurry, mud

Electrode material	Corrosion resistance and wear resistance
Stainless steel 0Crl8Nil2M02Ti	It is used for weakly corrosive media such as industrial water, domestic water, and sewage. It is suitable for industrial sectors such as petroleum, chemicals, and steel, as well as municipal and environmental protection fields.
Hastelloy B	It has good corrosion resistance to hydrochloric acid of all concentrations below the boiling point, and is also resistant to corrosion by sulfuric acid, phosphoric acid, hydrofluoric acid, organic acids and other non-chlorinating acids and alkalis, and non-oxidizing salt liquids.
Hastelloy C	It is resistant to corrosion by non-oxidizing acids, such as nitric acid, mixed acid, or mixed media of chromic acid and sulfuric acid, and is also resistant to corrosion by oxidizing salts such as Fc+, Cu+ or other oxidizing agents, such as hypochlorite above normal temperature. Corrosion from solutions and seawater
Titanium	It can withstand corrosion from seawater, various chlorides and hypochlorites, oxidizing acids (including oleum), organic acids and alkali. It is not resistant to corrosion by relatively pure reducing acids (such as sulfuric acid, hydrochloric acid), but if the acid contains oxidants (such as nitric acid, Fc+, Cu+), the corrosion is greatly reduced.
Tantalum	It has excellent corrosion resistance and is very similar to glass. In addition to hydrofluoric acid, fuming sulfuric acid, and alkali, it is almost resistant to corrosion by chemical media (including boiling hydrochloric acid, nitric acid, and sulfuric acid below 50°C). Resistant to alkali; resistant to corrosion.
Platinum/titanium alloy	It is resistant to almost all chemical media, but is not suitable for aqua regia and ammonium salts.
Stainless steel coated tungsten carbide	For non-corrosive, highly abrasive media.
Note: Since there are many types of media and their corrosiveness is affected by complex factors such as temperature, concentration, flow rate, etc., this table is for reference only. Users should make their own choices based on the actual situation. If necessary, they should conduct corrosion resistance tests on the selected materials, such as coupon tests.

Installationsforholdsregler

1. Det skal installeres i den nedre del og den lodrette opadgående del af den vandrette rørledning og undgå at installere på det højeste punkt og den lodrette nedad del af rørledningen som vist i figur 1;

2. Det skal installeres ved stigningspunktet for rørledningen;

3. Ved installation i et åbent udladningsrør skal det installeres i den nedre del af røret;

4. Hvis rørfaldet overstiger 5 m, skal du installere en udstødningsventil nedstrøms for sensoren;

5. Sensoren må ikke installeres ved indløbet og udløbet af pumpen, men skal installeres ved udløbet af pumpen.
