The solvent flow meter is a flow meter that can measure solvent volume or mass flow. In the industrial production process, it is very important to accurately measure the amount of solvent. Solvents are divided into organic solvents and inorganic solvents according to their chemical composition. Solvents are commonly used raw materials in various industries such as coatings, paints, and dyes.

Solvent flow meters

Solvent refers to a substance that can dissolve other solids, liquids, gases, and other solutes. The most common solvent in our daily lives is water. Generally, the solvent has a low boiling point and is easy to volatilize, and the solvent cannot produce a chemical reaction to the solute. Solvents are generally colorless and transparent liquids with unique odors.

Solvents play a very important role in adhesives.

Organic solvents are a large class of organic compounds that are widely used in life and production. They have a small molecular weight and are liquid at room temperature. Organic solvents include many types of substances, such as paraffin, alkenes, alcohols, aldehydes, amines, esters, ethers, ketones, aromatic hydrocarbons, hydrogenated hydrocarbons, terpene olefins, halogenated hydrocarbons, heterocyclic compounds, nitrogen-containing compounds, and sulfur-containing compounds, etc. Etc. Most of them are toxic to the human body.

Solvents are generally found in paints, adhesives, lacquers, and cleaners. Commonly used organic solvents include DMF, cyclohexanone, acetonitrile, acetic acid, methyl acetate, ethyl acetate, isopropanol, vinyl acetate, cyclohexane, n-hexane, n-heptane, etc.

Organic solvents are a class of organic compounds that can dissolve some water-insoluble substances (such as grease, wax, resin, rubber, dyes, etc.). Its characteristic is that it is liquid at room temperature and pressure. It has greater volatility. In dissolution During the process, the properties of the solute and solvent are unchanged.

There are many types of organic solvents, which can be divided into 10 categories according to their chemical structure:

①Aromatic hydrocarbons: benzene, toluene, xylene, etc.;
②Aliphatic hydrocarbons: pentane, hexane, octane, etc.;
③ Alicyclic hydrocarbons: cyclohexane, cyclohexanone, toluene cyclohexanone, etc.;
④ Halogenated hydrocarbons: chlorobenzene, dichlorobenzene, dichloromethane, etc.;
⑤Alcohols: methanol, ethanol, isopropanol, etc.;
⑥Ethers: ether, propylene oxide, etc.;
⑦Esters: methyl acetate, ethyl acetate, propyl acetate, etc.;
⑧ Ketones: acetone, methyl butanone, methyl isobutyl ketone, etc.;
⑨Diol derivatives: ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, etc.;
⑩Others: acetonitrile, pyridine, phenol, etc.

Solvent flow meter – Oval Gear

An Oval Gear flowmeter as a mechanical flow meter is a common type of Volumetric Flow Meter. It can measure the volume flow of high viscosity and corrosive Solvent fluids.

Volumetric Flow Meters
  • High measurement accuracy;
  • The installation pipeline conditions have no influence on the measurement accuracy;
  • Can be used for high-viscosity liquids;
  • Wide range;
  • The direct-reading meter can directly obtain the cumulative and total amount without external energy.
  • Clear and clear, easy to operate.

Solvent flow meter – Turbine

Turbine flow meters are velocity flow meters, also called impeller flow meters. Can be used to measure the instantaneous flow and cumulative flow of Solvent liquids.


Turbine flowmeters are widely used in flow measurement: petroleum, organic liquids, inorganic liquids, liquefied gas, natural gas, coal gas and cryogenic fluids. Turbine flowmeter signals can be divided into pulse signals or current signals (4-20mA). It is suitable for use with secondary display, PLC, DCS and other computer control systems.

Turbine Flow Meter reference price: USD 200-1700/pc.

Solvent flow meter – Electromagnetic

Magnetic Flow Meter is a flow meter that measures the flow of conductive Solvent fluids. Abbreviated as EMF, also called Electromagnetic flowmeters. It is a kind of Volumetric flow meter. A magnetic flow meter measures the velocity of conductive liquids moving through a pipe or conduit. In the wastewater treatment industry, Magnetic Flow Meter is the best flow meter choice.

Electromagnetic flowmeter as waste water flowmeter
  • Measures liquids or liquid slurries that have a minimum conductivity of 5 µS/cm.
  • Sanitary type, PTFE anticorrosive materials are optional.
  • Clamps, flanges, insertion installation are optional.
  • Battery powered optional.
  • Low cost.
  • DN 6 to DN2000
  • High precision: 0.5%, 0.2% optional

Solvent flow meter – Gear

Gear flow meter for Micro flow

Gear flow meter is a micro digital positive displacement flow meter. Can measure very small flow rates and quantify small volumes of liquid. High and low-temperature resistance (-196℃-200℃).

The Gear flow meter for Microflow is made of stainless steel and is used for precise continuous or intermittent measurement of the flow or instantaneous flow of liquid. It is especially suitable for the flow measurement of heavy oil, polyvinyl alcohol, grease, and other high-viscosity media. It can measure the viscosity of Fluid up to 10000Pa.s.

Generally speaking, we can choose a suitable flow meter according to the different characteristics of chemical solvents. For example, high-viscosity solvents are recommended to use gear flow meters. For example, for corrosive solvents, electromagnetic flowmeters can be used. If you need to reduce costs, you can choose a turbine flowmeter.

Of course, it needs to be based on our actual measurement conditions, such as the temperature of the medium, the temperature of the pipeline, the pressure, and so on. Select the appropriate flow meter to achieve accurate measurement.
