What is solvent circulate meter?
Solvent flow meter is a flow meter that measures the amount 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 various industries similar to coatings, paints and dyes.
Choosing a circulate meter for chemical service can be tricky. We must know precisely what the fluid is and the operating circumstances. Of explicit importance are temperature and line strain. The extra info you give us, the better we will do in selecting the proper flow meter for your utility.
What is a chemical solvent?
Solvents are substances that may dissolve other solids, liquids, gases and other solutes. The commonest solvent in our day by day life is water. Generally solvents have low boiling points, are volatile and can’t react chemically with solutes. Solvents are usually colorless and transparent liquids with a particular odor.
Solvents play a vital function in adhesives.
Organic solvents are a big group of organic compounds that are widely utilized in life and production. They have a small molecular weight and are liquid at room temperature. Organic solvents include a big selection of substances corresponding to paraffins, olefins, alcohols, aldehydes, amines, esters, ethers, ketones, fragrant hydrocarbons, hydrogenated hydrocarbons, terpenes, halogenated hydrocarbons, heterocyclic compounds, nitrogen-containing compounds, sulfur-containing compounds, etc. Compounds, and so forth. Most of them are poisonous to humans.
Solvents are often found 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 class of organic 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 strain. It has greater volatility. During the dissolution process, the properties of solute and solvent stay unchanged.
There are many kinds of organic solvents, which can be divided into 10 main categories based on their chemical structure.
Aromatic hydrocarbons: benzene, toluene, xylene, etc.
Aliphatic hydrocarbons: pentane, hexane, octane, and so on.
Alicyclic hydrocarbons: cyclohexane, cyclohexanone, toluene cyclohexanone, and so forth.
Halogenated hydrocarbons: chlorobenzene, dichlorobenzene, dichloromethane, and so forth.
Alcohols: methanol, ethanol, isopropanol, and so on.
Ethers: ethyl ether, propylene oxide, and so on.
Esters: methyl acetate, ethyl acetate, propyl acetate, etc.
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 flow meter
Don’t simply ask for body material and anticipate the gauge to work properly. The body is just a stress vessel containing a working mechanism. The supplies in the physique must be carefully specified. Always examine the list of materials in the specs. If you expertise chemical compatibility issues, it will be in the working mechanism, not in the physique.
Do not assume that a plastic-bodied gauge will give you the outcomes you want merely since you are using PVC lines. PVC and CPVC can deal with chemicals that will soften a plastic-bodied gauge in seconds. Plastic body gauges designed for water supply are manufactured from polyacetal and polycarbonate, not PVC. they can’t handle low pH fluids and are topic to solvent attack in some cases.
Viscosity considerations and lack of capillary seal
The utility of mechanical instruments requires consideration of fluid properties. Mechanical gauges with oscillating pistons, pendulums (pendulums) or related measuring components are called volumetric gauges. However, what makes it “positive” is the capillary seal between the measuring component and the sidewall or partaking components. If you’re 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 around the measuring element and will normally trigger the meter to read low.
Low lubricity and pressure drop
Positive displacement flow meters have surfaces within the measurement chamber that are in contact with each other. In a chapter shifting disc (pendulum), the middle ball rides in a fashioned cup, in an oscillating piston flowmeter, the center pin is in touch with the roller and the piston diaphragm rides on the hub. This implies that the non-lubricated fluid permits these elements to drag in opposition to each other, which will increase the frictional load. This loading creates higher strain drops and increases wear on the meter.
Flow meters for measuring solvents
The greatest method for such fluids is to make use of turbine move meters. The turbine rotor is suspended by ball or sleeve bearings and has nearly no drag coefficient. This permits turbine circulate meters to be used for low viscosity in addition to non-lubricated fluids. Another possibility is the oval gear circulate meter (PD circulate meter), which is a positive displacement gadget using a double oval rotor. The rotors inherently present a greater seal as a result of their gear design captures a pocket of fluid on the capillary sealing point, thus stopping leakage around the measuring factor. Electromagnetic circulate meters can additionally be used, and so they each permit for highly correct and efficient solvent flow measurement.
Turbine flowmeter
Turbine circulate meters are velocity flow meters, also known as impeller circulate meters. เกจวัดแรงดันน้ำดิจิตอล can be utilized to measure the instantaneous and cumulative flow fee of solvent liquids. It has the advantages of excessive accuracy, good repeatability, easy structure, few shifting elements, excessive stress resistance, extensive measuring range, small quantity, mild weight, small stress loss, easy upkeep, and so on.
Turbine flowmeter is broadly used for circulate measurement: petroleum, chemical trade, metallurgy, natural liquid, inorganic liquid, liquefied gas, pure gasoline, fuel and low temperature fluid. Turbine flowmeter sign could be divided into pulse sign or current sign (4-20mA).
Oval gear circulate meter
Oval gear move meter as a mechanical move meter is a standard sort of volumetric circulate meter. It can measure the amount move of excessive 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 range.
Direct reading meter can acquire the totalization and total immediately without external energy.
Clear and easy to function.
Magnetic flowmeter
Magnetic move meter is a flowmeter that measures the circulate of conductive solvent fluids. Abbreviated as EMF, it’s also known as electromagnetic flowmeter. It is a volumetric circulate meter. The electromagnetic move meter measures the velocity of a conductive fluid passing through a pipe or conduit. Electromagnetic flowmeter is one of the best flowmeter selection for the wastewater treatment business.
Gear flow meter
The gear move meter is a miniature digital volumetric flow meter. Can measure very small move rates and quantify small volumes of liquid. Resistant to excessive and low temperatures (-196°C – 200°C).
The gear circulate meter is made from stainless steel and is used for correct continuous or intermittent measurement of the move rate or instantaneous circulate of liquids. It is especially suitable for circulate measurement of heavy oil, polyvinyl alcohol, grease and other excessive viscosity media. It can measure the viscosity of fluids up to 10,000 Pa.s.
Generally talking, we are able to select the appropriate flowmeter based on the totally different characteristics of chemical solvents. For example, excessive viscosity solvents are recommended to make use of gear move meters. For example, for corrosive solvents, electromagnetic flowmeter can be utilized. If you want to scale back the fee, you possibly can select turbine flowmeter.
Of course have to be based on our precise measurement conditions, corresponding to media temperature, pipe temperature, stress, and so forth.. Select the suitable flowmeter to realize correct measurement.
