Which flowmeter is the most accurate? In-depth analysis of 5 types of high-precision flowmeter.
There are many types of flowmeters on the market, how to choose the flowmeter with the highest accuracy and suitable for the application scenario, the following measurement of liquid media as an example, focusing on comparing 5 types of mainstream flowmeters.
Accuracy comparison:
1. Coriolis flow meter
1. Prioritize Medium Characteristics
1. Regular Calibration: It is recommended to conduct third-party certified calibration every 12 months.
2. Correct Installation: Ensure the length of the straight pipe sections before and after the flowmeter to avoid turbulence interference.
Industry Application Recommendations
There is no absolutely "most accurate" flowmeter, only the solution that best suits the working conditions. It is recommended to contact a professional engineer for medium analysis and on-site investigation to obtain a customized selection plan.

Accuracy comparison:
1. Coriolis flow meter
- Accuracy level: ±0.1%~0.2%
- Direct measurement of mass flow, independent of temperature, pressure and conductivity
- Applicable medium: liquid, gas and high viscosity fluid
- Accuracy level: ±0.5%~1%
- Non-contact measurement, no pressure loss
- High installation requirements, need full pipe flow
- Accuracy level: ±0.2%~0.5%
- Conductive liquid measurement only
- Strong anti-pollution ability, low maintenance cost
- Accuracy level: ±0.5%~1%
- Very high fluid cleanliness requirements
- Often used in oil and fuel measurement
- Accuracy level: ±1%~1.5%
- Specializes in steam flow measurement, but also can be used for liquid measurement
- Fast response, suitable for process control
1. Prioritize Medium Characteristics
- For conductive liquids, electromagnetic flow meters are preferred.
- For fluids with impurities, Coriolis flow meters are recommended.
- For gas measurement, thermal or ultrasonic flow meters should be considered.
- Flow meters should be avoided in vibrating locations to avoid interference
- Although Coriolis flow meters have a high purchase cost, their maintenance-free design can reduce long-term usage costs.
1. Regular Calibration: It is recommended to conduct third-party certified calibration every 12 months.
2. Correct Installation: Ensure the length of the straight pipe sections before and after the flowmeter to avoid turbulence interference.
Industry Application Recommendations
- Chemical Industry: Coriolis flow meters (for precise measurement of high-value raw materials)
- Water Treatment Plants: Electromagnetic flow meters (cost-effective solution)
- Non-stop Working Transmission: Ultrasonic flow meters (advantageous for large-diameter pipelines)
There is no absolutely "most accurate" flowmeter, only the solution that best suits the working conditions. It is recommended to contact a professional engineer for medium analysis and on-site investigation to obtain a customized selection plan.
