Liquid Volumetric Flowmeter, Precise Measurement, Suitable For Various Liquid Media
A liquid volumetric flowmeter is a high-precision measuring instrument that divides a fixed volume of liquid through moving parts and converts the rotational speed into flow rate.
There are mainly the following types of liquid volumetric flowmeters, which have different structures but share the same principle:
| Type | Core Features | Applications |
|---|---|---|
| Oval gear flowmeter | Simple structure, moderate cost, viscosity adaptability 0.3~8mPa・s | Lubricating oil, syrup, general chemical liquids |
| Roots flowmeter | High viscosity compatibility (0.6~1000mPa・s), accuracy ±0.2% | Heavy oil, asphalt, resin and other high viscosity media |
| Double rotor flowmeter | Extra low pressure loss, resistant to sandy media (sand content ≤5%), accuracy ±0.1% | Crude oil transportation, viscous liquids with impurities |
| Screw flowmeter | Uniform sealed chamber, supports bidirectional measurement, accuracy ±0.2% | Food, medicine, fine chemical clean liquids |
Liquid volumetric flowmeters are synonymous with precision and reliability. They measure the volume of fluid in the most direct mechanical way, and hold an unshakable dominant position in the precise measurement of medium to high viscosity liquids. Despite their strict requirements for medium cleanliness and pressure loss, their unparalleled accuracy and insensitivity to viscosity make them irreplaceable key equipment in trade handovers and critical process control in industries such as petroleum, chemical engineering, and food.
