What is solvent circulate meter?
Solvent move meter is a circulate meter that measures the amount or mass move of a solvent. It is essential to precisely measure the amount of solvent in industrial manufacturing processes. Solvents are divided into natural solvents and inorganic solvents according to their chemical composition. Solvents are generally used as raw supplies in various industries similar to coatings, paints and dyes.
Choosing a circulate meter for chemical service could be tricky. We need to know exactly what the fluid is and the working circumstances. Of explicit importance are temperature and line stress. The more data you give us, the better we are in a position to do in choosing the best circulate meter for your utility.
What is a chemical solvent?
Solvents are substances that can dissolve other solids, liquids, gases and other solutes. The commonest solvent in our daily life is water. Generally solvents have low boiling points, are volatile and cannot react chemically with solutes. Solvents are normally colorless and transparent liquids with a distinctive odor.
Solvents play an important position in adhesives.
Organic solvents are a big group of organic compounds that are extensively utilized in life and production. They have a small molecular weight and are liquid at room temperature. Organic solvents include quite a lot of substances such as paraffins, olefins, alcohols, aldehydes, amines, esters, ethers, ketones, aromatic hydrocarbons, hydrogenated hydrocarbons, terpenes, halogenated hydrocarbons, heterocyclic compounds, nitrogen-containing compounds, sulfur-containing compounds, and so on. Compounds, etc. Most of them are poisonous to humans.
Solvents are often found in paints, adhesives, varnishes and cleaners. Commonly used organic solvents are DMF, cyclohexanone, acetonitrile, acetic acid, methyl acetate, ethyl acetate, isopropyl alcohol, vinyl acetate, cyclohexane, n-hexane, n-heptane, etc.
Organic solvents are a category of natural compounds that can dissolve some substances insoluble in water (such as grease, wax, resin, rubber, dye, etc.). It is characterized by its liquid state at room temperature and strain. It has greater volatility. During the dissolution process, the properties of solute and solvent stay unchanged.
There are many kinds of natural solvents, which may be divided into 10 major classes according to their chemical structure.
Aromatic hydrocarbons: benzene, toluene, xylene, and so forth.
Aliphatic hydrocarbons: pentane, hexane, octane, etc.
Alicyclic hydrocarbons: cyclohexane, cyclohexanone, toluene cyclohexanone, and so forth.
Halogenated hydrocarbons: chlorobenzene, dichlorobenzene, dichloromethane, etc.
Alcohols: methanol, ethanol, isopropanol, etc.
Ethers: ethyl ether, propylene oxide, etc.
Esters: methyl acetate, ethyl acetate, propyl acetate, and so on.
Ketones: acetone, methyl butanone, methyl isobutyl ketone, and so on.
Diol derivatives: ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, etc.
Other: acetonitrile, pyridine, phenol, etc.
Considerations for selecting a solvent move meter
Don’t simply ask for body material and expect the gauge to work properly. The body is just a stress vessel containing a working mechanism. The materials within the physique must be carefully specified. Always check the listing of supplies in the specs. If you expertise chemical compatibility issues, it will be in the working mechanism, not in the body.
Do not assume that a plastic-bodied gauge will give you the results you want simply since you are utilizing PVC lines. PVC and CPVC can handle chemicals that may melt a plastic-bodied gauge in seconds. Plastic body gauges designed for water provide are made of polyacetal and polycarbonate, not PVC. they can not deal with low pH fluids and are topic to solvent attack in some circumstances.
Viscosity issues and lack of capillary seal
The utility of mechanical devices requires consideration of fluid properties. Mechanical gauges with oscillating pistons, pendulums (pendulums) or comparable measuring elements are known as volumetric gauges. However, what makes it “positive” is the capillary seal between the measuring element and the sidewall or partaking elements. If you are coping with low viscosity fluids, i.e. alcohol, toluene, MEK, etc., you lack the viscosity to form an excellent capillary seal. This will show up as leaks across the measuring component and will usually cause the meter to learn low.
Low lubricity and stress drop
Positive displacement circulate meters have surfaces within the measurement chamber which would possibly be in touch with each other. In a chapter shifting disc (pendulum), the center ball rides in a fashioned cup, in an oscillating piston flowmeter, the middle pin is in contact with the roller and the piston diaphragm rides on the hub. This means that the non-lubricated fluid permits these components to drag in opposition to each other, which will increase the frictional load. This loading creates greater strain drops and will increase wear on the meter.
Flow meters for measuring solvents
The greatest technique for such fluids is to use turbine flow meters. The turbine rotor is suspended by ball or sleeve bearings and has just about no drag coefficient. This permits turbine move meters for use for low viscosity as properly as non-lubricated fluids. Another option is the oval gear circulate meter (PD flow meter), which is a constructive displacement system utilizing a double oval rotor. The rotors inherently provide a greater seal because their gear design captures a pocket of fluid on the capillary sealing level, thus stopping leakage around the measuring component. Electromagnetic circulate meters can be used, and so they each allow for highly correct and efficient solvent flow measurement.
Turbine flowmeter
Turbine circulate meters are velocity move meters, also called impeller move meters. It can be utilized to measure the instantaneous and cumulative flow price of solvent liquids. It has the advantages of excessive accuracy, good repeatability, easy structure, few shifting components, excessive pressure resistance, broad measuring range, small volume, light weight, small strain loss, straightforward upkeep, and so forth.
Turbine flowmeter is widely used for circulate measurement: petroleum, chemical business, metallurgy, natural liquid, inorganic liquid, liquefied gasoline, natural fuel, fuel and low temperature fluid. Turbine flowmeter sign could be divided into pulse signal or present sign (4-20mA).
Oval gear move meter
Oval gear circulate meter as a mechanical circulate meter is a standard kind of volumetric circulate meter. It can measure the amount circulate of excessive viscosity and corrosive solvent fluids. It has several advantages.
ราคาเพรสเชอร์เกจ .
Installation piping circumstances don’t have any effect on the measurement accuracy.
Can be used for top viscosity fluids.
Large range.
Direct studying meter can obtain the totalization and complete directly with out external vitality.
Clear and easy to operate.
Magnetic flowmeter
Magnetic move meter is a flowmeter that measures the circulate of conductive solvent fluids. Abbreviated as EMF, it is also referred to as electromagnetic flowmeter. It is a volumetric move meter. The electromagnetic circulate meter measures the speed of a conductive fluid passing through a pipe or conduit. Electromagnetic flowmeter is the most effective flowmeter alternative for the wastewater treatment industry.
Gear circulate meter
The gear flow meter is a miniature digital volumetric move meter. Can measure very small circulate charges and quantify small volumes of liquid. Resistant to excessive and low temperatures (-196°C – 200°C).
The gear move meter is manufactured from chrome steel and is used for correct continuous or intermittent measurement of the flow fee or instantaneous flow of liquids. It is particularly appropriate for flow measurement of heavy oil, polyvinyl alcohol, grease and different high viscosity media. It can measure the viscosity of fluids as a lot as 10,000 Pa.s.
Generally speaking, we will choose the suitable flowmeter based on the different traits of chemical solvents. For example, high viscosity solvents are recommended to make use of gear circulate meters. For instance, for corrosive solvents, electromagnetic flowmeter can be utilized. If you have to cut back the cost, you’ll have the ability to select turbine flowmeter.
Of course need to be based mostly on our actual measurement situations, similar to media temperature, pipe temperature, strain, etc.. Select the appropriate flowmeter to attain correct measurement.
