Outline:
????The SKLD series electromagnetic flowmeter survey principle is the Faraday law of electromagnetic induction, the sensor key component is: Measuring tube, electrode, exciting coil, ferrite core and magnetic yoke shell. It mainly uses in surveying in solid surrounding boundary's electric conduction liquid and the size rate of volume flow. Including acid, alkali, salt and so on strong corrosive liquid. This product widely applies in professions as well as the environmental protection, the municipal administration management and so on petroleum, chemical industry, metallurgy, spinning and weaving, food, drugs manufacture, papermaking, domains and so on water conservancy facility.

Product characteristic:
1st, survey not fluid density, viscosity, temperature, pressure and conductivity change influence;
2nd, in the measuring tube the free from obstacle flowing part, does not have the damaged due to pressing, the straight length of pipe request is low;
3rd, series nominal size DN15~DN3000. The sensor lining and the electrode material has the multiple options;
4th, the switch selects the novel excitation method, the power loss is low, zero stable, the precision is high. The current capacity scope may reach 1500:1;
5th, the switch may compose a build with the sensor or the separation;
6th, the switch uses 16 high performance microprocessors, 2x16LCD demonstrated that the parameter hypothesis is convenient, the programming is reliable;
7th, flowmeter for bidirectional measurement system, internal installation three integrators: Forward total quantity, reverse total quantity and differential value total quantity; May demonstrate. The village, the counter-current capacity, and have many kinds of outputs: Electricity
??? Class, pulse, digital communication, HART;
8th, the switch uses surface mounting technical (SMT), has self-checking and from the diagnosis function;

Lining material

Main performance

Highest medium temperature

Applicable scope

- build

Separation

Teflon (F4)

Is the chemical properties stablest one kind of plastic, the ability ebullition hydrochloric acid, the sulfuric acid, the nitric acid and the aqua regia, also ability thick alkali and each organic solvent. Does not bear the boron trifluoride chlorine, the high temperature boron trifluoride chlorine, the high flow rate liquid fluorine, the liquid oxygen, from the oxygen corrosion.

70℃

100℃ 150℃ (needs special orders)

1st, concentrated acid, alkali and so on strong corrosive medium. 2nd, health class medium.

Gathers the entire fluorine second grade propylene (F46)

With F4, the resistance to wear, anti-negative pressure ability are higher than F4.

With on

Gathers the fluorine to gather the ethylene (Fs)

Is suitable the temperature upper limit to compare the teflon to be low, but the cost is also low.

80℃

Gathers the chloroprene rubber

1st, has the extremely good elasticity, the altitude breaking tenacity, the wear-resisting performance is good. 2nd, bears the general low concentration acid, the alkali, the salty medium corrosion, does not bear the oxidized medium the corrosion.

80℃ 120℃ (needs special orders)

Water, sewage, weak wearability mud pulp.

Polyurethane rubber

1st, the wear-resisting performance is greatly strengthened.

2nd, the anti-corrosive performance is bad.

80℃

Neutral strong attrition pulp, coal tar, mud

Flange type

Applicable scope

Earth flange (or earth link)

Is suitable in the non-conductor pipeline, if plastic pipeline, but has earth electrode's sensor not to need.

Import protection flange

When the medium has the strong wearability selects.

Electrode material

Anticorrosion and wear-resisting performance

Stainless steel 0Crl8Nil2M02Ti

Uses in the process water, the domestic water, the sewage and so on having the pickling medium, is suitable in Industry sectors and so on petroleum, chemical industry, steel and iron and, domains and so on municipal administration, environmental protection.

Alloy B

Has the good corrosion resistance to below the boiling point all density's hydrochloric acid, also bears the sulfuric acid, the phosphoric acid, the hydrofluoric acid, the organic acid and so on non-chlorination acid, the alkali, non-oxidized salty fluid corrosion.

Alloy C

Ability non-oxidized acid, like nitric acid, nitration mixture, or chromic acid and sulfuric acid mix medium corrosion, also bears the oxidized salt as for example: Fe,”, Cu” under or including other oxidant's corrosion, like is higher than the normal temperature the hypochlorous acid salt brine, the sea water corrosion

Titanium

Ability sea water, each kind of chloride and hypochlorite, oxidized acid (including fuming sulfuric acid), organic acid, alkali corrosion. Does not bear the pure reducible acid (for example sulfuric acid, hydrochloric acid) corrosion, but like in the acid includes the oxidant (for example nitric acid, Fc++, Cu++) time, then corrodes to reduce greatly.

Tantalum

Has the fine corrosion resistance and the glass is very similar. Besides the hydrofluoric acid, the fuming sulfuric acid, the alkali, the ability - - cuts the chemical mediator nearly (including boiling point hydrochloric acid, nitric acid and the l 50℃ following sulfuric acid) the corrosion. In alkali tricky; Anticorrosion.

Platinum/titanium alloy

The ability - - cuts the chemical mediator nearly, but is not suitable for the aqua regia and the ammonium salt.

Stainless steel spreading tungsten carbide

Uses in non-corrosiveness, strong wearability medium.

Note: As a result of the medium great variety, its corrosiveness receives the temperature, the density, the speed of flow and so on complex factor influence to change, therefore this table only supplies the reference. The user should act according to actual situation make the choice, when the necessity should do plans to choose the material the anticorrosive experiment, like lacing film experiment.
