Before you place the order, we can provide technical consultation and model selection services. After you place the order, we will offer technical guides involving with equipment installation and commissioning. Additionally, one-year product warranty is provided.
The delivery cycle is usually 7 work days, and paid samples are available as well. If you have any technical issues regarding to our products, please email your questions to email@example.com. We will reply as soon as possible.
Yes, we do. We are happy to offer custom measuring instruments, calibration instruments, control valves, etc. according to client-side application demands.
Electromagnetic flowmeters are compatible with various conductive liquids such as water, sewage water, beer, slurry, saline solution, strong acid, strong alkali, etc.
(1) 316L stainless steel electrodes: Ideal for industrial water, domestic water, polluted water, etc. with weak corrosion. Electromagnetic flowmeters with 316L stainless steel electrodes are often applied in petroleum chemical industry, steel and iron industry, as well as government and environmental protection fields.
(2) Hastelloy B coated electrodes: Have good corrosion resistance, and thus compatible with alkali, non-oxidized salty fluid, hydrochloric acid below the boiling point, as well as non-chlorine acids such as sulfuric acid, phosphoric acid, hydrofluoric acid, organic acid, etc.
(3) Hastelloy C coated electrodes: Offer great resistance to the erosion of oxide salt, seawater, non-oxidized acid (such as nitric acid, nitration mixture, etc. ), the mixture of chromic acid and sulfuric acid, oxidizers (such as sodium hypochlorite aqueous solution), etc.
(4) Titanium electrodes: Resistant to the erosion of sea water, all kinds of chloride and hypochlorite, oxidizing acid (such as Fuming sulfuric acid), organic acid, alkali; but not resistant to the erosion of purer reducing acids (such as sulfuric acid, hydrochloric acid).
Electromagnetic flowmeters with titanium electrodes are also compatible with acids containing oxidizers (such as nitric acid, and mediums containing iron ion, copper ion, etc.) because of reduced corrosion.
(5) Tantalum electrodes: Have comparable corrosion resistance with glass. Excluding alkali, hydrofluoric acid and fuming nitric acid, tantalum electrodes are resistant to the corrosion of almost all chemical mediums (including boiling hydrochloric acid, nitric acid, and sulfuric acid below 150℃),.
(6) Pt/ Iridium alloy electrodes: Resistant to nearly all chemicals, excluding aquaregia and ammonium salt.
(7) Stainless steel coated tungsten carbide electrodes: Fit for non-corrosive mediums without strong attrition.
(1) The installation dimension should be accurate. Or else, the electromagnetic flowmeter may leak or may not be installed.
(2) Keep the flow direction of fluids the same as that marked on flow sensor.
(3) Electrode axis of flowmeter must be approximately horizontal; otherwise the measuring accuracy will be affected.
(4) Flange at two sides of the sensor must keep parallel; otherwise there will be leakage.
(5) To avoid forming of whirlpool, the process pipe, sealing elements, and the flowmeter should share the same axis during installation.
(6) No welding near the flange of flowmeter during installation process, lest the linear of flowmeter be burned.
(7) For different process pipes, corresponding sensor earthing methods should be utilized.
(8) For corrosive mediums, it is better to install the flowmeter vertically, allowing the measured medium to flow from down to up. This can prevent the solid particles from depositing in the pipe of flowmeter, thus ensuring uniform erosion to the liner and prolonging the service life.
(9) When the pipe diameter exceeds 200mm, telescopic fittings can be applied so as to make installation convenient.
Gases, liquids and steam, with max. temperature not exceeding 350℃.
Flanges meeting GB, ANSI, JIS, DIN, BS, or SABS standards
