What is the difference between magnetic flow meter and mass flow meter?
Instruments that measure fluid flow are collectively called flowmeters. Flowmeters are one of the important instruments in industrial measurement. In industrial production and processing, the most commonly used flow meters are mass flow meters and electromagnetic flow meters.
1. The working principles are different.
An electromagnetic liquid flow meter is a flow meter that determines the flow rate by measuring the electromagnetic induction phenomenon in conductive liquids. Its working principle is based on Faraday’s law of electromagnetic induction and measures flow through the electromotive force generated when the fluid passes through a magnetic field. Electromagnetic liquid flowmeter is suitable for measuring conductive liquids, such as water, solutions, etc.
A mass flow meter determines the flow rate by measuring the mass of the fluid as it flows through the pipe. The commonly used working principles of mass flow meters include thermal measurement, time-of-flight measurement and oscillating tube measurement, which are suitable for flow measurement of various media.
2. The accuracy and measurement range are different.
Electromagnetic liquid flow meters and mass flow meters also differ in accuracy and measurement range.
The measurement range of electromagnetic liquid flowmeters is generally large, ranging from tens of cubic meters/hour to several thousand cubic meters/hour, while the measurement range of mass flow meters is relatively small, generally ranging from several thousand kilograms/hour to tens of tons/hour. between hours.
In terms of accuracy, the accuracy of electromagnetic liquid flow meters is usually 0.5%~1%, while the accuracy of mass flow meters can reach 0.1%~0.5%. Therefore, mass flow meters are more suitable where high-precision measurement is required, such as in petrochemical, pharmaceutical and other industries.
3. Application requirements are different.
Electromagnetic liquid flow meters and mass flow meters also have slightly different application scenarios and usage requirements.
Electromagnetic liquid flowmeter is suitable for measuring various conductive liquids, and can still work normally in harsh environments such as high temperature and high pressure.
Mass flow meters are suitable for measuring various media, including gases and liquids. And can achieve high precision and stable measurement. Choosing a suitable flow meter based on actual needs is the key to ensuring the accuracy and reliability of flow measurement.
What is a sewer flow meter?
Sewer flow meter is a type of instrument used to measure sewage flow. Also called Sewage flow meter. It has a wide range of applications and can be used in water supply and drainage engineering, water resources management, environmental monitoring and other fields. Sewage flow meters provide strong technical support for sewage treatment and environmental protection work.
The most commonly used sewage flow meter is the electromagnetic flow meter. I thought I could choose corrosion-resistant lining and electrode materials. And won’t clog.
If the sewage pipe is not full, you can choose our partial electromagnetic flowmeter.
