What is solvent flow meter?
Solvent move meter is a circulate meter that measures the volume or mass circulate of a solvent. It is very important to accurately measure the amount of solvent in industrial production processes. Solvents are divided into natural solvents and inorganic solvents according to their chemical composition. Solvents are generally used as raw supplies in varied industries corresponding to coatings, paints and dyes.
Choosing a move meter for chemical service may be tricky. We must know exactly what the fluid is and the operating conditions. Of particular significance are temperature and line stress. The extra information you give us, the better we will do in deciding on 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 daily life is water. Generally solvents have low boiling points, are volatile and can’t react chemically with solutes. Solvents are usually colorless and clear liquids with a distinctive odor.
Solvents play a vital role in adhesives.
Organic solvents are a big group of natural compounds which are widely used in life and manufacturing. They have a small molecular weight and are liquid at room temperature. Organic solvents embody a 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, and so forth. Compounds, etc. 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, etc.
Organic solvents are a category of natural compounds that may dissolve some substances insoluble in water (such as grease, wax, resin, rubber, dye, and so forth.). It is characterised by its liquid state at room temperature and stress. It has greater 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 categories based on their chemical construction.
Aromatic hydrocarbons: benzene, toluene, xylene, etc.
Aliphatic hydrocarbons: pentane, hexane, octane, and so on.
Alicyclic hydrocarbons: cyclohexane, cyclohexanone, toluene cyclohexanone, etc.
Halogenated hydrocarbons: chlorobenzene, dichlorobenzene, dichloromethane, and so on.
Alcohols: methanol, ethanol, isopropanol, and so forth.
Ethers: ethyl ether, propylene oxide, etc.
Esters: methyl acetate, ethyl acetate, propyl acetate, and so forth.
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, and so on.
Considerations for selecting a solvent flow meter
Don’t simply ask for physique material and anticipate the gauge to work properly. The body is simply a stress vessel containing a working mechanism. The supplies within the physique must be carefully specified. Always check the record of supplies within the specs. If you experience chemical compatibility issues, will probably be within the working mechanism, not in the body.
Do not assume that a plastic-bodied gauge will be good for you simply since you are using PVC traces. PVC and CPVC can deal with chemical compounds that may soften a plastic-bodied gauge in seconds. Plastic physique gauges designed for water provide are manufactured from polyacetal and polycarbonate, not PVC. they cannot handle low pH fluids and are topic to solvent assault in some cases.
Viscosity concerns and lack of capillary seal
The application of mechanical instruments requires consideration of fluid properties. Mechanical gauges with oscillating pistons, pendulums (pendulums) or related measuring parts are known as volumetric gauges. However, what makes it “positive” is the capillary seal between the measuring element and the sidewall or engaging elements. If you may be coping 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 across the measuring factor and can often cause the meter to read low.
Low lubricity and pressure drop
Positive displacement flow meters have surfaces within the measurement chamber which are in contact with each other. In a chapter shifting disc (pendulum), the middle 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 pull against 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 best method 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 permits turbine move meters for use for low viscosity as nicely as non-lubricated fluids. Another choice is the oval gear flow meter (PD circulate meter), which is a optimistic displacement system utilizing a double oval rotor. The rotors inherently present a better seal as a end result of their gear design captures a pocket of fluid on the capillary sealing point, thus preventing leakage around the measuring factor. Electromagnetic move meters may also be used, they usually both allow for extremely accurate and efficient solvent circulate measurement.
Turbine flowmeter
Turbine circulate meters are velocity flow meters, also referred to as impeller circulate meters. It can be utilized to measure the instantaneous and cumulative flow price of solvent liquids. It has the benefits of excessive accuracy, good repeatability, simple construction, few transferring elements, excessive stress resistance, wide measuring range, small volume, mild weight, small stress loss, easy maintenance, and so forth.
Turbine flowmeter is broadly used for circulate measurement: petroleum, chemical industry, metallurgy, organic liquid, inorganic liquid, liquefied fuel, natural gas, gasoline and low temperature fluid. Turbine flowmeter sign may 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 typical type of volumetric circulate meter. It can measure the amount circulate 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 high viscosity fluids.
Large vary.
Direct reading meter can get hold of the totalization and total immediately with out exterior energy.
Clear and easy to function.
Magnetic flowmeter
Magnetic flow meter is a flowmeter that measures the move of conductive solvent fluids. Abbreviated as EMF, additionally it is called electromagnetic flowmeter. It is a volumetric flow meter. The electromagnetic circulate meter measures the speed of a conductive fluid passing by way of a pipe or conduit. Electromagnetic flowmeter is one of the best flowmeter alternative for the wastewater treatment industry.
Gear circulate meter
The gear move meter is a miniature digital volumetric move meter. Can measure very small flow charges and quantify small volumes of liquid. Resistant to high and low temperatures (-196°C – 200°C).
The gear flow meter is made from stainless steel and is used for correct steady or intermittent measurement of the circulate price or instantaneous flow of liquids. It is very suitable for circulate 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 speaking, we can choose the appropriate flowmeter in accordance with the totally different characteristics of chemical solvents. For instance, high viscosity solvents are recommended to use gear flow meters. For example, for corrosive solvents, electromagnetic flowmeter can be utilized. If you have to cut back the fee, you’ll find a way to choose turbine flowmeter.
Of course must be primarily based on our precise measurement conditions, such as media temperature, pipe temperature, stress, and so on.. Select the appropriate flowmeter to realize correct measurement.
