What is solvent flow meter?
Solvent move meter is a flow meter that measures the volume or mass flow of a solvent. It is very important to accurately measure the quantity of solvent in industrial manufacturing processes. Solvents are divided into organic solvents and inorganic solvents based on their chemical composition. เกจวัดแรงลม are generally used as uncooked materials in varied industries corresponding to coatings, paints and dyes.
Choosing a move meter for chemical service may be difficult. We have to know precisely what the fluid is and the working circumstances. Of specific significance are temperature and line strain. The extra data you give us, the higher we are able to do in deciding on the right circulate meter for your utility.
What is a chemical solvent?
Solvents are substances that can dissolve different solids, liquids, gases and other solutes. The most typical 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 particular odor.
Solvents play a vital role in adhesives.
Organic solvents are a large group of natural compounds which might be broadly utilized in life and manufacturing. They have a small molecular weight and are liquid at room temperature. Organic solvents include quite so much of substances similar to 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 forth. Compounds, etc. Most of them are toxic to humans.
Solvents are usually present 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, and so forth.
Organic solvents are a class of organic compounds that may dissolve some substances insoluble in water (such as grease, wax, resin, rubber, dye, and so on.). It is characterized by its liquid state at room temperature and strain. It has larger volatility. During the dissolution process, the properties of solute and solvent stay unchanged.
There are many types of natural solvents, which could be divided into 10 major classes according to their chemical construction.
Aromatic hydrocarbons: benzene, toluene, xylene, and so forth.
Aliphatic hydrocarbons: pentane, hexane, octane, and so on.
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, 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 on.
Considerations for choosing a solvent flow meter
Don’t simply ask for physique material and anticipate the gauge to work correctly. The body is just a strain vessel containing a working mechanism. The supplies in the body have to be rigorously specified. Always verify the record of materials in the specs. If you experience chemical compatibility problems, will in all probability be within the working mechanism, not in the body.
Do not assume that a plastic-bodied gauge will give you the results you want merely since you are using PVC traces. PVC and CPVC can handle chemical substances that may soften a plastic-bodied gauge in seconds. Plastic body gauges designed for water provide are made of polyacetal and polycarbonate, not PVC. they can’t handle low pH fluids and are topic to solvent attack in some instances.
Viscosity issues and lack of capillary seal
The utility of mechanical instruments requires consideration of fluid properties. Mechanical gauges with oscillating pistons, pendulums (pendulums) or similar measuring parts are known as volumetric gauges. However, what makes it “positive” is the capillary seal between the measuring factor and the sidewall or partaking parts. If you are dealing with low viscosity fluids, i.e. alcohol, toluene, MEK, etc., you lack the viscosity to form a great capillary seal. This will present up as leaks across the measuring factor and can usually trigger the meter to read low.
Low lubricity and strain drop
Positive displacement move meters have surfaces within the measurement chamber which are in contact with each other. In a chapter transferring disc (pendulum), the middle 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 implies that the non-lubricated fluid permits these parts to drag against one another, which increases the frictional load. This loading creates larger pressure drops and will increase wear on the meter.
Flow meters for measuring solvents
The finest method for such fluids is to make use of turbine flow meters. The turbine rotor is suspended by ball or sleeve bearings and has nearly 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 flow meter), which is a constructive displacement device utilizing a double oval rotor. The rotors inherently present a greater seal because their gear design captures a pocket of fluid at the capillary sealing level, thus stopping leakage around the measuring element. Electromagnetic move meters can be used, they usually both enable for extremely correct and efficient solvent move measurement.
Turbine flowmeter
Turbine move meters are velocity flow meters, also called impeller circulate meters. It can be utilized to measure the instantaneous and cumulative circulate rate of solvent liquids. It has the advantages of high accuracy, good repeatability, simple structure, few moving elements, excessive pressure resistance, extensive measuring range, small volume, light weight, small strain loss, simple upkeep, and so forth.
Turbine flowmeter is broadly used for flow measurement: petroleum, chemical business, metallurgy, natural liquid, inorganic liquid, liquefied gasoline, pure gasoline, gas and low temperature fluid. Turbine flowmeter signal may be divided into pulse sign or present signal (4-20mA).
Oval gear move meter
Oval gear flow meter as a mechanical move meter is a standard type of volumetric circulate meter. It can measure the volume move of excessive viscosity and corrosive solvent fluids. It has several benefits.
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 reading meter can get hold of the totalization and whole instantly with out external energy.
Clear and simple to operate.
Magnetic flowmeter
Magnetic circulate meter is a flowmeter that measures the flow of conductive solvent fluids. Abbreviated as EMF, additionally it is referred to as electromagnetic flowmeter. It is a volumetric flow meter. The electromagnetic move meter measures the velocity of a conductive fluid passing through a pipe or conduit. Electromagnetic flowmeter is the best flowmeter selection for the wastewater remedy business.
Gear move meter
The gear flow meter is a miniature digital volumetric circulate meter. Can measure very small flow rates and quantify small volumes of liquid. Resistant to high and low temperatures (-196°C – 200°C).
The gear circulate meter is manufactured from chrome steel and is used for correct continuous or intermittent measurement of the move price or instantaneous move of liquids. It is particularly appropriate for flow measurement of heavy oil, polyvinyl alcohol, grease and different excessive viscosity media. It can measure the viscosity of fluids up to 10,000 Pa.s.
Generally talking, we will select the suitable flowmeter based on the totally different characteristics of chemical solvents. For instance, high viscosity solvents are really helpful to make use of gear circulate meters. For example, for corrosive solvents, electromagnetic flowmeter can be utilized. If you want to scale back the price, you can choose turbine flowmeter.
Of course need to be based mostly on our actual measurement situations, similar to media temperature, pipe temperature, pressure, etc.. Select the appropriate flowmeter to attain accurate measurement.
