What is solvent flow meter?
Solvent flow meter is a flow meter that measures the volume or mass circulate of a solvent. It is essential to accurately measure the amount of solvent in industrial manufacturing processes. Solvents are divided into organic solvents and inorganic solvents in accordance with their chemical composition. Solvents are commonly used as raw materials in varied industries such as coatings, paints and dyes.
Choosing a flow meter for chemical service may be tricky. We must know precisely what the fluid is and the operating conditions. Of particular significance are temperature and line stress. The extra info you give us, the better we will do in deciding on the right circulate meter for your application.
What is a chemical solvent?
Solvents are substances that may dissolve other solids, liquids, gases and different solutes. The most common solvent in our day by day life is water. Generally solvents have low boiling points, are risky and cannot react chemically with solutes. Solvents are often colorless and transparent liquids with a distinctive odor.
Solvents play a very important function in adhesives.
Organic solvents are a big group of natural compounds which are widely utilized in life and production. They have a small molecular weight and are liquid at room temperature. Organic solvents embrace quite so much of substances such as paraffins, olefins, alcohols, aldehydes, amines, esters, ethers, ketones, fragrant hydrocarbons, hydrogenated hydrocarbons, terpenes, halogenated hydrocarbons, heterocyclic compounds, nitrogen-containing compounds, sulfur-containing compounds, and so on. Compounds, and so on. Most of them are poisonous to people.
Solvents are normally present in paints, adhesives, varnishes and cleaners. Commonly used natural solvents are DMF, cyclohexanone, acetonitrile, acetic acid, methyl acetate, ethyl acetate, isopropyl alcohol, vinyl acetate, cyclohexane, n-hexane, n-heptane, and so on.
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 characterised by its liquid state at room temperature and stress. It has higher volatility. During the dissolution course of, the properties of solute and solvent remain unchanged.
There are many kinds of organic solvents, which may be divided into 10 major categories based on their chemical structure.
Aromatic hydrocarbons: benzene, toluene, xylene, and so forth.
Aliphatic hydrocarbons: pentane, hexane, octane, and so forth.
Alicyclic hydrocarbons: cyclohexane, cyclohexanone, toluene cyclohexanone, and so forth.
Halogenated hydrocarbons: chlorobenzene, dichlorobenzene, dichloromethane, and so on.
Alcohols: methanol, ethanol, isopropanol, etc.
Ethers: ethyl ether, propylene oxide, etc.
Esters: methyl acetate, ethyl acetate, propyl acetate, and so forth.
Ketones: acetone, methyl butanone, methyl isobutyl ketone, and so on.
Diol derivatives: ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, and so forth.
Other: acetonitrile, pyridine, phenol, and so forth.
Considerations for selecting a solvent flow meter
Don’t simply ask for body material and expect the gauge to work correctly. The body is just a stress vessel containing a working mechanism. The materials within the physique must be fastidiously specified. Always examine the listing of supplies within the specs. If you experience chemical compatibility issues, it goes to be within the working mechanism, not in the body.
Do not assume that a plastic-bodied gauge will work for you merely since you are using PVC lines. PVC and CPVC can handle chemicals that will soften a plastic-bodied gauge in seconds. Plastic body gauges designed for water provide are manufactured from polyacetal and polycarbonate, not PVC. they can not deal with low pH fluids and are subject to solvent assault in some circumstances.
Viscosity concerns and lack of capillary seal
The utility of mechanical instruments requires consideration of fluid properties. Mechanical gauges with oscillating pistons, pendulums (pendulums) or comparable measuring components are known as volumetric gauges. However, what makes it “positive” is the capillary seal between the measuring component and the sidewall or engaging elements. If you are coping with low viscosity fluids, i.e. alcohol, toluene, MEK, etc., you lack the viscosity to kind a good capillary seal. This will show up as leaks across the measuring element and will normally cause the meter to read low.
Low lubricity and stress drop
Positive displacement move meters have surfaces in the measurement chamber which might be in touch with one another. In a chapter moving disc (pendulum), the center ball rides in a fashioned cup, in an oscillating piston flowmeter, the center pin is in contact with the curler and the piston diaphragm rides on the hub. This implies that the non-lubricated fluid permits these components to tug against each other, which will increase the frictional load. This loading creates higher strain drops and will increase put on on the meter.
Flow meters for measuring solvents
The best methodology for such fluids is to make use of 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 to be used for low viscosity in addition to non-lubricated fluids. Another option is the oval gear circulate meter (PD move meter), which is a optimistic 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 preventing leakage across the measuring element. Electromagnetic circulate meters can also be used, they usually both allow for highly accurate and environment friendly solvent move measurement.
Turbine flowmeter
Turbine move meters are velocity move meters, also called impeller flow meters. It can be utilized to measure the instantaneous and cumulative move fee of solvent liquids. It has some great advantages of high accuracy, good repeatability, simple structure, few moving components, excessive stress resistance, broad measuring vary, small volume, light weight, small stress loss, simple upkeep, and so forth.
Turbine flowmeter is extensively used for circulate measurement: petroleum, chemical industry, metallurgy, natural liquid, inorganic liquid, liquefied fuel, natural gas, gasoline and low temperature fluid. Turbine flowmeter signal could be divided into pulse signal or present sign (4-20mA).
Oval gear circulate meter
Oval gear move meter as a mechanical move meter is a standard sort of volumetric move meter. It can measure the volume flow of high viscosity and corrosive solvent fluids. It has several advantages.
High measurement accuracy.
Installation piping situations don’t have any impact on the measurement accuracy.
Can be used for top viscosity fluids.
Large vary.
Direct studying meter can acquire the totalization and whole instantly with out exterior vitality.
Clear and simple to operate.
Magnetic flowmeter
Magnetic flow meter is a flowmeter that measures the circulate of conductive solvent fluids. Abbreviated as EMF, additionally it is known as electromagnetic flowmeter. It is a volumetric circulate meter. The electromagnetic flow meter measures the rate of a conductive fluid passing via a pipe or conduit. Electromagnetic flowmeter is one of the best flowmeter selection for the wastewater treatment trade.
Gear circulate meter
The gear circulate meter is a miniature digital volumetric move meter. Can measure very small circulate rates and quantify small volumes of liquid. Resistant to high and low temperatures (-196°C – 200°C).
The gear move meter is made from stainless steel and is used for correct continuous or intermittent measurement of the circulate fee or instantaneous flow of liquids. It is very appropriate for move measurement of heavy oil, polyvinyl alcohol, grease and different high viscosity media. It can measure the viscosity of fluids up to 10,000 Pa.s.
Generally talking, we are in a position to select the suitable flowmeter based on the completely different characteristics of chemical solvents. For instance, high viscosity solvents are recommended to use gear move meters. For instance, for corrosive solvents, electromagnetic flowmeter can be used. If you have to reduce the fee, you possibly can choose turbine flowmeter.
Of course must be based mostly on our precise measurement circumstances, such as media temperature, pipe temperature, strain, and so forth.. Select the appropriate flowmeter to realize correct measurement.
