What is solvent flow meter?
Solvent flow meter is a move meter that measures the amount or mass circulate of a solvent. It is essential to precisely measure the quantity of solvent in industrial production processes. Solvents are divided into organic solvents and inorganic solvents based on their chemical composition. Solvents are generally used as uncooked supplies in numerous industries corresponding to coatings, paints and dyes.
Choosing a move meter for chemical service may be difficult. We need to know exactly what the fluid is and the working circumstances. Of specific significance are temperature and line strain. The more information you give us, the higher we can do in selecting the proper move meter on your utility.
What is a chemical solvent?
Solvents are substances that may dissolve different solids, liquids, gases and other solutes. The commonest solvent in our every day life is water. Generally solvents have low boiling factors, are risky and can’t react chemically with solutes. Solvents are usually colorless and transparent liquids with a particular odor.
Solvents play an important role in adhesives.
Organic solvents are a big group of organic compounds that are extensively used in life and manufacturing. They have a small molecular weight and are liquid at room temperature. Organic solvents include a wide range of substances corresponding to 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 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 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 stay unchanged.
There are many forms of natural solvents, which may be divided into 10 major classes according to their chemical structure.
Aromatic hydrocarbons: benzene, toluene, xylene, and so on.
Aliphatic hydrocarbons: pentane, hexane, octane, and so forth.
Alicyclic hydrocarbons: cyclohexane, cyclohexanone, toluene cyclohexanone, etc.
Halogenated hydrocarbons: chlorobenzene, dichlorobenzene, dichloromethane, etc.
Alcohols: methanol, ethanol, isopropanol, and so forth.
Ethers: ethyl ether, propylene oxide, and so forth.
Esters: methyl acetate, ethyl acetate, propyl acetate, etc.
Ketones: acetone, methyl butanone, methyl isobutyl ketone, and so forth.
Diol derivatives: ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, and so on.
Other: acetonitrile, pyridine, phenol, and so on.
Considerations for choosing a solvent circulate meter
Don’t just ask for physique materials and anticipate the gauge to work correctly. The physique is solely a strain vessel containing a working mechanism. The supplies within the physique have to be fastidiously specified. Always verify the listing of materials in the specs. If you expertise chemical compatibility problems, it will be in the working mechanism, not in the body.
Do not assume that a plastic-bodied gauge will be good for you merely since you are utilizing PVC strains. PVC and CPVC can deal with chemical substances that may soften a plastic-bodied gauge in seconds. Plastic physique gauges designed for water supply are made from polyacetal and polycarbonate, not PVC. they can not handle low pH fluids and are topic to solvent attack in some circumstances.
Viscosity concerns and lack of capillary seal
The application of mechanical devices requires consideration of fluid properties. Mechanical gauges with oscillating pistons, pendulums (pendulums) or related measuring parts are called volumetric gauges. However, what makes it “positive” is the capillary seal between the measuring component and the sidewall or partaking parts. If you may be dealing with low viscosity fluids, i.e. alcohol, toluene, MEK, etc., you lack the viscosity to kind a great capillary seal. This will show up as leaks around the measuring component and can usually trigger the meter to learn low.
Low lubricity and stress drop
Positive displacement circulate meters have surfaces in the measurement chamber which might be in contact with each other. In a chapter moving disc (pendulum), the middle ball rides in a formed cup, in an oscillating piston flowmeter, the middle pin is involved with the roller and the piston diaphragm rides on the hub. This implies that the non-lubricated fluid allows these elements to pull against each other, which increases the frictional load. This loading creates higher strain drops and increases wear on the meter.
Flow meters for measuring solvents
The finest methodology for such fluids is to make use of turbine flow meters. The turbine rotor is suspended by ball or sleeve bearings and has virtually no drag coefficient. This permits turbine move meters for use for low viscosity in addition to non-lubricated fluids. Another option is the oval gear flow meter (PD circulate meter), which is a positive displacement gadget using a double oval rotor. The rotors inherently provide a greater seal as a end result of their gear design captures a pocket of fluid on the capillary sealing level, thus stopping leakage around the measuring component. Electromagnetic move meters may additionally be used, and so they both allow for extremely correct and efficient solvent move measurement.
Turbine flowmeter
Turbine circulate meters are velocity circulate meters, also called impeller circulate meters. It can be used to measure the instantaneous and cumulative flow price of solvent liquids. It has the benefits of high accuracy, good repeatability, simple construction, few shifting elements, high strain resistance, extensive measuring range, small quantity, gentle weight, small stress loss, simple maintenance, etc.
Turbine flowmeter is broadly used for move measurement: petroleum, chemical trade, metallurgy, organic liquid, inorganic liquid, liquefied gasoline, natural gas, fuel and low temperature fluid. Turbine flowmeter signal could be divided into pulse sign or present sign (4-20mA).
Oval gear flow meter
Oval gear flow meter as a mechanical move meter is a standard type of volumetric move meter. It can measure the amount circulate of high viscosity and corrosive solvent fluids. It has several advantages.
High measurement accuracy.
Installation piping conditions don’t have any effect on the measurement accuracy.
Can be used for prime viscosity fluids.
Large vary.
Direct reading meter can get hold of the totalization and total immediately with out external power.
Clear and simple to operate.
Magnetic flowmeter
Magnetic circulate meter is a flowmeter that measures the circulate of conductive solvent fluids. Abbreviated as EMF, it’s also called electromagnetic flowmeter. It is a volumetric circulate meter. The electromagnetic move meter measures the speed of a conductive fluid passing through a pipe or conduit. Electromagnetic flowmeter is the best flowmeter alternative for the wastewater remedy industry.
Gear move 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 flow meter is manufactured from stainless steel and is used for correct continuous or intermittent measurement of the circulate rate or instantaneous move of liquids. It is very suitable for move measurement of heavy oil, polyvinyl alcohol, grease and other excessive viscosity media. It can measure the viscosity of fluids as a lot as 10,000 Pa.s.
Generally talking, we are able to select the suitable flowmeter based on the different characteristics of chemical solvents. For example, high viscosity solvents are beneficial to make use of gear circulate meters. For example, for corrosive solvents, electromagnetic flowmeter can be utilized. If you need to cut back the price, you probably can choose turbine flowmeter.
Of course must be based on our actual measurement situations, corresponding to media temperature, pipe temperature, pressure, etc.. Select the appropriate flowmeter to attain accurate measurement.
