Selection of imported protective flanges and grounding flanges or grounding rings

Type of flange	Scope of application
Grounding flange or grounding ring	Suitable for non-conductive pipelines such as plastic pipes, but sensors with grounding electrodes do not require them.
Import protection flange	Choose when the medium has strong wear resistance.

Selection of electrodes

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, hydrogen 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:Fe，'Cu'Corrosion caused by or containing other oxidants, such as hypochlorite solutions above room temperature and seawater corrosion
Titanium	Capable of withstanding corrosion from seawater, various chlorides and hypochlorites, oxidizing acids including fuming sulfuric acid, organic acids, and alkalis. Not resistant to corrosion by relatively pure reducing acids such as sulfuric acid and hydrochloric acid, but if the acid contains oxidants such as nitric acidFc++CuWhen++, corrosion is greatly reduced.
Tantalum	It has excellent corrosion resistance and is very similar to glass. Except for hydrogen acid, fuming sulfuric acid, and alkali, it can withstand almost all chemical media including boiling point hydrochloric acid, nitric acid, andl 50℃Corrosion caused by sulfuric acid. 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.

Selection of TKLD-B series explosion-proof flowmeter instruments
◆ Range confirmation
Explosion proof flow meters for general industrial use measure the flow rate of the measured medium2～4m/sIn special circumstances, the low flow rate should not be less than0.2m/sThe height should not exceed8m/sIf the medium contains solid particles, the commonly used flow rate should be less than3m/sTo prevent excessive friction between the lining and electrodes; For viscous fluids, the flow velocity can be selected to be greater than2m/sA higher flow rate helps to automatically eliminate the effect of viscous substances attached to the electrode, which is beneficial for improving measurement accuracy.
Within the rangeQUnder the determined conditions, the above flow rate can be usedVThe range determines the diameter of the flowmeterDThe size of is calculated by the following formula:
Q=πD2V/4
Q:Flow rate (㎡)/h）D:inner diameter of pipeV: Flow rate（m/h）
Range of explosion-proof flowmeterQIt should be greater than the expected large flow rate value, while the normal flow rate value should be slightly greater than the full-scale scale of the flow meter50It is appropriate.
