What is solvent circulate meter?
Solvent flow meter is a flow meter that measures the quantity or mass circulate of a solvent. เพรสเชอร์เกจ is essential to precisely measure the quantity of solvent in industrial manufacturing processes. Solvents are divided into organic solvents and inorganic solvents based on their chemical composition. Solvents are commonly used as uncooked supplies in varied industries similar to coatings, paints and dyes.
Choosing a move meter for chemical service could be tricky. We have to know precisely what the fluid is and the working situations. Of specific importance are temperature and line pressure. The more info you give us, the better we will do in selecting the right flow meter for your utility.
What is a chemical solvent?
Solvents are substances that can dissolve other solids, liquids, gases and other solutes. The most typical solvent in our day by day life is water. Generally solvents have low boiling factors, are unstable and cannot react chemically with solutes. Solvents are usually colorless and transparent liquids with a distinctive odor.
Solvents play a very important function 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 variety 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, and so on. Most of them are toxic to humans.
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, etc.
Organic solvents are a category of organic compounds that can 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 higher volatility. During the dissolution process, the properties of solute and solvent remain unchanged.
There are many types of organic solvents, which may be divided into 10 main classes based on their chemical structure.
Aromatic hydrocarbons: benzene, toluene, xylene, and so forth.
Aliphatic hydrocarbons: pentane, hexane, octane, and so on.
Alicyclic hydrocarbons: cyclohexane, cyclohexanone, toluene cyclohexanone, and so on.
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, and so on.
Other: acetonitrile, pyridine, phenol, and so on.
Considerations for choosing a solvent circulate meter
Don’t simply ask for physique materials and expect the gauge to work correctly. The physique is just a pressure vessel containing a working mechanism. The supplies within the physique should be rigorously specified. Always check the record of materials in the specs. If you experience chemical compatibility issues, will most likely be within the working mechanism, not within the physique.
Do not assume that a plastic-bodied gauge will work for you merely because you are using PVC lines. PVC and CPVC can handle chemicals that may soften a plastic-bodied gauge in seconds. Plastic body gauges designed for water supply are made from polyacetal and polycarbonate, not PVC. they can’t deal with low pH fluids and are subject to solvent attack in some circumstances.
Viscosity considerations and lack of capillary seal
The software of mechanical instruments requires consideration of fluid properties. Mechanical gauges with oscillating pistons, pendulums (pendulums) or comparable measuring components are called volumetric gauges. However, what makes it “positive” is the capillary seal between the measuring element and the sidewall or engaging components. If you may be coping with low viscosity fluids, i.e. alcohol, toluene, MEK, and so forth., you lack the viscosity to form an excellent capillary seal. This will present up as leaks around the measuring element and can usually trigger the meter to learn low.
Low lubricity and strain drop
Positive displacement flow meters have surfaces within the measurement chamber that are in contact with each other. In a chapter moving disc (pendulum), the center ball rides in a shaped 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 allows these components to drag towards each other, which will increase the frictional load. This loading creates greater strain drops and will increase put on on the meter.
Flow meters for measuring solvents
The greatest technique for such fluids is to use turbine move meters. The turbine rotor is suspended by ball or sleeve bearings and has just about no drag coefficient. This allows turbine flow meters to be used for low viscosity as properly as non-lubricated fluids. Another choice is the oval gear move meter (PD move meter), which is a constructive displacement system using a double oval rotor. The rotors inherently present a better seal as a result of their gear design captures a pocket of fluid on the capillary sealing point, thus stopping leakage around the measuring component. Electromagnetic move meters may additionally be used, they usually each allow for highly accurate and environment friendly solvent circulate measurement.
Turbine flowmeter
Turbine circulate meters are velocity move meters, also referred to as impeller flow meters. It can be used to measure the instantaneous and cumulative flow rate of solvent liquids. It has the benefits of excessive accuracy, good repeatability, simple construction, few moving elements, excessive strain resistance, wide measuring vary, small volume, light weight, small stress loss, easy upkeep, and so on.
Turbine flowmeter is broadly used for move measurement: petroleum, chemical trade, metallurgy, organic liquid, inorganic liquid, liquefied fuel, pure gasoline, gasoline and low temperature fluid. Turbine flowmeter sign may be divided into pulse sign or current sign (4-20mA).
Oval gear flow meter
Oval gear circulate meter as a mechanical flow meter is a standard kind of volumetric circulate meter. It can measure the volume flow of high 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 range.
Direct studying meter can acquire the totalization and whole directly with out exterior vitality.
Clear and simple to function.
Magnetic flowmeter
Magnetic circulate meter is a flowmeter that measures the move 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 by way of a pipe or conduit. Electromagnetic flowmeter is the best flowmeter alternative for the wastewater treatment industry.
Gear flow meter
The gear circulate meter is a miniature digital volumetric circulate meter. Can measure very small circulate rates and quantify small volumes of liquid. Resistant to excessive and low temperatures (-196°C – 200°C).
The gear flow meter is made from stainless steel and is used for correct continuous or intermittent measurement of the flow rate or instantaneous flow of liquids. It is particularly suitable 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 appropriate flowmeter in accordance with the totally different characteristics of chemical solvents. For instance, excessive viscosity solvents are beneficial to use gear move meters. For example, for corrosive solvents, electromagnetic flowmeter can be used. If you have to reduce the price, you’ll be able to select turbine flowmeter.
Of course must be based mostly on our actual measurement conditions, corresponding to media temperature, pipe temperature, stress, and so forth.. Select the suitable flowmeter to realize correct measurement.
