What electrode material should be used to measure liquid aluminum nitrate?

How to farm and what electrode material should be used electromagnetic flowmeter can be calculated, according to the battery and magnetic induction calculator can be basic to his uncle's amount.

The nature and flow of the fluid determines the form and size of the flow meter. First of all, the selection should consider several key physical and chemical properties of the fluid: the state of the fluid (solid gaseous or liquid), the conductivity of the fluid, the chemical corrosivity of the fluid, and the viscosity of the fluid.

Secondly, it is necessary to fully understand the application range of various forms of flow meters. The physical and chemical properties of the fluid should be comprehensively considered in the selection. The fluid in the solid state is generally dust or block, and there are only three types of flowmeters: impulse flowmeter, belt scale and rail scale.

There are many forms of flow meters for fluids in liquid and gaseous states, and there are series and models of general flow meters dedicated to gas measurement, for example, the Coriolis mass flow meter we use has a series of models dedicated to gas measurement. In the case of poor liquid working conditions, it is not corrosive, conductive, and with solid particles, in which case it is best to choose an electromagnetic flowmeter.

What electrode material electromagnetic flowmeter should be used for liquid aluminum nitrate, generally this liquid aluminum nitrate is used with PM C collector material electromagnetic flowmeter.

Key points for the selection of radar level sensors.

The selection of the right level gauge can ensure better use, the selection of what kind of radar level gauge should be determined according to the physical and chemical properties of the measured fluid medium, so that the diameter of the level gauge, the flow range, the lining material, the electrode material and the output current, etc., can adapt to the nature of the measured fluid and the requirements of flow measurement.

A: General commodity PAC Eternal Night 10% concentration.

The flow measurement of ammonium nitrate can be measured by an electromagnetic mass flowmeter, and the conductivity of ammonium nitrate is relatively high, which is greater than 5us cm of the electromagnetic flow hood.

5% potassium nitrate liquid code code, can be used to use the electro-land magnetic flowmeter to measure the flow rate, its conductivity is to meet the requirements of use.

The first consideration in the selection of electrode materials for electromagnetic flowmeters is the corrosiveness of the measured medium, and the second consideration is whether there will be surface effects such as passivation and the noise formed. For the electromagnetic flowmeter, the corrosion resistance of the electrode is very high, and it is not allowed or only allowed to have a very low corrosion rate, otherwise the sealing between the electrode and the lining will be damaged, resulting in the flowmeter not working normally. Therefore, in principle, the selection of the electrode material needs to be determined by the user who is familiar with the field conditions by drawing on the actual application and previous experience of the measured medium in other equipment.

In general, the corrosion resistance of electrode materials is one level higher than that of pipe materials. For general media, you can consult the relevant anti-corrosion manuals, and for mixed acids and other complex compositions, you should do a hanging piece test, so as to draw a more reliable conclusion.

The corrosion resistance of the electromagnetic flowmeter electrode is an important factor in the selection of electrode materials, but sometimes the electrode material has good corrosion resistance to the measured medium, but it is not necessarily the suitable material, and the surface effect of the electrode should be avoided. The surface effect of the electrode can be divided into three aspects: surface chemical effect, electrochemical and polarization phenomenon, and catalyst effect of the electrode. Lower electrode material corrosion resistance measurement liquid example stainless steel SUS 316L can not be used for inorganic acids, organic acids, chlorides, domestic and industrial water, sewage Hastelloy C is not suitable for chloride, sulfuric acid, suitable for frictional fluids, seawater, sodium tantalum sulfate, suitable for almost all chemicals, but for hydrofluoric acid, fuming nitric acid is still problematic, aqua regia titanium is suitable for sodium chloride, sulfide, lye, but not for hydrochloric acid, sulfuric acid and nitrate, acetic acid, sodium chloride platinum Iridium alloy is suitable for almost all chemicals, but not for aqua regia and ammonium sodium hydroxide, concentrated tungsten sulfate can resist the interference of solid particles, and cannot be used for inorganic acids, organic acids, chloride pulp, sewage Examples of how to avoid electrode surface effects.

The electrode is generally made of metal material with high hardness and low resistance. The most commonly used is the molybdenum-containing stainless steel electrode of SUS316L. To measure corrosive acid-base solutions or raw materials, tantalum electrodes, titanium electrodes, Harbin B, Harbin C and other materials can be selected according to the characteristics of the medium, which are some common materials for electrodes.

According to the anti-corrosion performance, you can use tantalum electrode, platinum electrode, titanium electrode, HC electrode, HB electrode, tungsten carbide electrode, niobium electrode, 316L electrode, you can consult me, it is the name.

Requirements 1 Side liquid 2 Liquid with a dielectric constant that is not too small Different companies have different requirements. Generally speaking, it is more difficult to measure below 10, so most of the electromagnetic is used in water treatment, chemical industry, and food.

It mainly measures acid, alkali, seawater and other conductive liquids that are highly corrosive or contain impurities.

Dalian Youke!! Pass by. Didn't grab the sofa, hope it helps.

Electromagnetic flowmeters mainly measure the flow rate of liquids or solids.

Electromagnetic flowmeter is used to measure the volume flow of conductive liquids and slurries in closed pipelines, such as water, sewage, slurry, pulp, various acids, alkalis, salt solutions, food slurries, etc., and is suitable for petroleum, chemical, electric power, mining and metallurgy, water supply and drainage, light industry, food and other industries.

Electromagnetic flowmeters are commonly used to measure liquids related to water, and in general, some liquids that are electrically conductive.

An electromagnetic flowmeter is an inductive instrument used to measure the volume flow rate of a conductive medium in a tube. According to Faraday's law of electromagnetic induction, when a conductor moves in a magnetic field to cut magnetic field lines, an induced electric potential is generated in the conductor, and the magnitude of the induced electric potential is proportional to the effective length of the conductor in the magnetic field and the speed at which the conductor moves perpendicular to the direction of the magnetic field in the magnetic field. Similarly, when a conductive fluid flows perpendicular to a magnetic field and cuts the magnetic induced force lines, it also generates an induced electric potential on the electrodes on both sides of the pipe.

Flow meters based on this principle can measure all liquids that can conduct electricity.

Electromagnetic flowmeters are characterized by the absence of moving parts, have high reliability, and can be used to measure the flow of various suspended solids, gasified vapors and viscous substances such as acids, alkalis, salt solutions, coal slurry, mineral slurry, mortar plaster, pulp, resin, rubber latex, synthetic fiber pulp and photosensitive latex. Electromagnetic flowmeters have been widely used in chemical industry, environmental protection, metallurgy, medicine, papermaking, water supply and drainage and other industrial technology and management departments. The electromagnetic flowmeter has good sealing performance and can also be used in tap water and sewer systems.

Electromagnetic flowmeters measure processes without contact with fluids and are suitable for use in the pharmaceutical, biochemical and food industries. Electromagnetic flowmeters can also detect blood flow.

Electromagnetic flowmeters mainly measure industrial sewage, textile wastewater, and other water treatment industries.

The electromagnetic flowmeter can measure a lot of media, such as the fluid that can conduct electricity, and the measurement accuracy of the electromagnetic flowmeter is also high.

Electromagnetic flowmeters can be used to measure the instantaneous and cumulative flow of all conductive liquids, as long as the conductivity is greater than 5 μs

The medium that can be measured by the electromagnetic flowmeter is as follows:

General conductive fluxes, such as: tap water, sewage, waste water and other water flows;

Corrosive liquids such as strong acids and alkalis;

The flow rate of two-phase liquid-solid suspended liquids such as slurry, mineral pulp, and paper pulp.

An electromagnetic flowmeter measures the flow rate of conductive liquids. For example, tap water, sewage, salt solution, acid and alkali solution, cement slurry, etc.

Tantalum (Ta) electrodes can be used to measure ferrous chloride in electromagnetic flowmeters.

The magnitude of the polarization voltage depends on the electrode material"Electrode potential"and the nature of the liquid, the measured value can range from a few mV to several hundred mV.

An electromagnetic flowmeter is a flowmeter that works using the principle of electromagnetic induction. A conductor passing through a magnetic field produces an electric potential, and the magnitude of the electric potential is related to the velocity of the conductor through the magnetic field. Similarly, when the conductive fluid passes through the magnetic field, an electric potential will be formed in the fluid, and the flow rate can be obtained by detecting the potential of the fluid through the electrode under the premise of a certain magnetic field strength and cross-sectional area of the pipeline.

Flowmeters that work according to this principle are electromagnetic flowmeters.

Electrode polarization refers to the formation of a galvanic layer when the electron conductor solution or molten salt comes into contact, resulting in a potential jump, which is called the electrode potential when the electron conductor comes into contact with the solution or molten salt. The voltage value that characterizes this potential is called the polarization voltage.

The polarization voltage on the electrode of an electromagnetic flowmeter depends on the electrode material"Electrode potential"and the nature of the liquid, the measured value can range from a few mV to several hundred mV. In fact, the contamination of the two electrodes during operation cannot be exactly the same symmetry, so the voltage on the two electrodes forms an asymmetrical differential mode signal, which is an important reason for the zero offset. Therefore, to check the electrode polarization voltage of the electromagnetic flowmeter, we should not only look at the size, but also see whether it is symmetrical.
