What is solvent circulate meter?
Solvent flow meter is a circulate meter that measures the volume or mass move of a solvent. It is very important to precisely measure the quantity of solvent in industrial manufacturing processes. Solvents are divided into natural solvents and inorganic solvents according to their chemical composition. Solvents are generally used as raw supplies in various industries such as coatings, paints and dyes.
Choosing a flow meter for chemical service could be tricky. We have to know exactly what the fluid is and the operating circumstances. Of explicit significance are temperature and line strain. The more information you give us, the better we can do in choosing the proper circulate meter in 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 daily life is water. Generally solvents have low boiling factors, are unstable and cannot react chemically with solutes. Solvents are usually colorless and clear liquids with a distinctive odor.
Solvents play an important position in adhesives.
Organic solvents are a big group of organic compounds that are broadly utilized in life and production. They have a small molecular weight and are liquid at room temperature. Organic solvents embody a wide selection 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, and so on. Most of them are toxic to humans.
Solvents are often 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 forth.
Organic solvents are a category 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 pressure. It has larger volatility. During the dissolution process, the properties of solute and solvent remain unchanged.
There are many kinds of organic solvents, which can be divided into 10 major classes in accordance with 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, and so on.
Ethers: ethyl ether, propylene oxide, etc.
Esters: methyl acetate, ethyl acetate, propyl acetate, etc.
Ketones: acetone, methyl butanone, methyl isobutyl ketone, etc.
Diol derivatives: ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, and so forth.
Other: acetonitrile, pyridine, phenol, etc.
Considerations for choosing a solvent flow meter
Don’t simply ask for body materials and expect the gauge to work correctly. The body is just a pressure vessel containing a working mechanism. The materials within the physique have to be carefully specified. Always verify the record of supplies within the specifications. If you experience chemical compatibility issues, it will be in the working mechanism, not within the physique.
Do not assume that a plastic-bodied gauge will work for you merely because you are utilizing PVC lines. pressure gauge and CPVC can deal with chemical substances that may melt a plastic-bodied gauge in seconds. Plastic physique gauges designed for water supply are manufactured from polyacetal and polycarbonate, not PVC. they can not handle low pH fluids and are topic to solvent assault in some instances.
Viscosity concerns and lack of capillary seal
The software 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 component and the sidewall or participating parts. If you’re coping with low viscosity fluids, i.e. alcohol, toluene, MEK, and so forth., you lack the viscosity to type an excellent capillary seal. This will show up as leaks around the measuring factor and can usually trigger the meter to read low.
Low lubricity and pressure drop
Positive displacement flow meters have surfaces in the measurement chamber which are involved with one another. In a chapter shifting disc (pendulum), the center ball rides in a shaped cup, in an oscillating piston flowmeter, the center pin is involved with the curler and the piston diaphragm rides on the hub. This signifies that the non-lubricated fluid allows these components to tug in opposition to each other, which will increase the frictional load. This loading creates higher pressure drops and will increase wear on the meter.
Flow meters for measuring solvents
The finest methodology for such fluids is to use turbine flow meters. The turbine rotor is suspended by ball or sleeve bearings and has just about no drag coefficient. This allows turbine move meters to be used for low viscosity as properly as non-lubricated fluids. Another choice is the oval gear flow meter (PD move meter), which is a positive displacement system utilizing 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 across the measuring component. Electromagnetic circulate meters can be used, and they both allow for extremely accurate and efficient solvent move measurement.
Turbine flowmeter
Turbine flow meters are velocity circulate meters, also called impeller circulate meters. It can be used to measure the instantaneous and cumulative flow fee of solvent liquids. It has the benefits of excessive accuracy, good repeatability, easy structure, few moving parts, high stress resistance, extensive measuring vary, small quantity, light weight, small strain loss, simple maintenance, etc.
Turbine flowmeter is widely used for flow measurement: petroleum, chemical industry, metallurgy, organic liquid, inorganic liquid, liquefied gasoline, natural gas, gasoline and low temperature fluid. Turbine flowmeter signal may be divided into pulse signal or current signal (4-20mA).
Oval gear flow meter
Oval gear move meter as a mechanical flow meter is a common kind of volumetric circulate meter. It can measure the volume move of high viscosity and corrosive solvent fluids. It has several benefits.
High measurement accuracy.
Installation piping conditions have no impact on the measurement accuracy.
Can be used for high viscosity fluids.
Large vary.
Direct studying meter can obtain the totalization and whole instantly with out exterior energy.
Clear and simple to function.
Magnetic flowmeter
Magnetic circulate meter is a flowmeter that measures the flow 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 velocity of a conductive fluid passing by way of a pipe or conduit. Electromagnetic flowmeter is the most effective flowmeter selection for the wastewater remedy trade.
Gear move meter
The gear circulate meter is a miniature digital volumetric flow 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 move meter is made from chrome steel and is used for accurate continuous or intermittent measurement of the move price or instantaneous circulate of liquids. It is especially appropriate for move measurement of heavy oil, polyvinyl alcohol, grease and different high viscosity media. It can measure the viscosity of fluids as much as 10,000 Pa.s.
Generally speaking, we will select the appropriate flowmeter according to the totally different characteristics of chemical solvents. For instance, excessive viscosity solvents are beneficial to make use of gear flow meters. For example, for corrosive solvents, electromagnetic flowmeter can be used. If you want to reduce the fee, you’ll have the ability to select turbine flowmeter.
Of course must be based on our actual measurement conditions, such as media temperature, pipe temperature, strain, and so on.. Select the appropriate flowmeter to realize accurate measurement.
