Overview

Platinum Measurement and Control specializes in producing clamp type electromagnetic flow meters. Welcome to consult with clamp type electromagnetic flow meter manufacturers. 1、 Overview of clamp type electromagnetic flowmeter products Platinum Rui clamp type sanitary electromagnetic flowmeter measures flow according to Faraday's law of electromagnetic induction. ...

Product Details

Platinum Rui clamp type sanitary electromagnetic flowmeter is used for flow measurement based on Faraday's law of electromagnetic induction. The advantages of electromagnetic flowmeter are minimal pressure loss and a wide range of measurable flow rates. The ratio of maximum flow rate to minimum flow rate is generally above 20:1, suitable for a wide range of industrial pipe diameters. The output signal is linear with the measured flow rate, with high accuracy, and can measure liquids with conductivity ≥ 5 μ s/cm.Clamp type electromagnetic flowmeter has the advantages of easy installation and cleaning, and is commonly used in food production, pharmaceutical industry pharmaceutical measurement, and water purification monitoringAs shown in Figure 1.

polyurethane rubber	2Poor corrosion resistance.		80℃	Neutral strong abrasion slurry, coal slurry, mud

4、 Electrode selection table for clamp type electromagnetic flowmeter

electrode material	Corrosion resistance and wear resistance
stainless steel0Crl8Nil2M02Ti	Used for weakly corrosive media such as industrial water, domestic water, sewage, etc., suitable for industrial sectors such as petroleum, chemical, steel, as well as municipal and environmental protection fields.
HastelloyB	It has good corrosion resistance to all concentrations of hydrochloric acid below boiling point, as well as to non chlorinated acids, bases, and non oxidizing salt solutions such as sulfuric acid, phosphoric acid, hydrofluoric acid, and organic acids.
HastelloyC	Can withstand corrosion from non oxidizing acids such as nitric acid, mixed acids, or mixed media of chromic acid and sulfuric acid, as well as oxidative salts such as:Corrosion under Fc+, Cu+or with other oxidants, such as corrosion in hypochlorite solutions above room temperature or seawater
Titanium	Capable of withstanding seawater, various chlorides and hypochlorites, and oxidizing acidsCorrosion caused by (including fuming sulfuric acid), organic acids, and alkalis. Not resistant to the corrosion of 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. Except for hydrofluoric acid, fuming sulfuric acid, and alkali, it can almost withstandCorrosion of a chemical medium (including boiling point hydrochloric acid, nitric acid, and sulfuric acid below 50 ℃). Dig in alkali; Corrosion resistance.
Platinum/titanium alloy	Can withstand almost all chemical media, but not suitable for aqua regia and ammonium salts.
Stainless steel coated with tungsten carbide	Used for non corrosive and highly abrasive media.
Note: Due to the wide variety of media and the complex factors such as temperature, concentration, and flow rate that affect their corrosiveness, this table is for reference only. Users should make their own choices based on the actual situation, and if necessary, conduct corrosion resistance tests on the selected materials, such as hanging plate tests.
