Portable ultrasonic flowmeter

The measuring instrument is one of the important instruments in water and petrochemical industries.For water resources industry, it is of special significance.For example, the addition of chemicals in the water supply industry, if the accuracy of relevant meters is not high, will directly affect the quality of water quality, and even affect the safety and health of users.

At present, there are many kinds of flow meters, such as: volumetric flowmeter, turbine flowmeter, vortex flowmeter, differential pressure flowmeter, open channel flowmeter, electromagnetic flowmeter, ultrasonic flowmeter, mass flowmeter and so on.In the water conservancy and water pollution industries, we made a rough statistics, among which the use scale of ultrasonic flowmeter and electromagnetic flowmeter is close to 85%, and the use of ultrasonic flowmeter has a rising trend with the development of its electronic technology.

Below, talking about electromagnetic flowmeter and ultrasonic flowmeter advantages and disadvantages, for peer reference.

The electromagnetic flowmeter type is based on the electromagnetic induction law (cutting the magnetic force line) to work the flow meter:

Its features:

High measurement accuracy and good repeatability.

The price is proportional to the diameter of the pipe

The measured medium is required to have certain conductivity

Features of ultrasonic flowmeter:

No moving parts, no pressure loss

No requirement for fluid physical properties

Non-contact measurement

The cost has nothing to do with the size of the pipe

Easy installation, no need to stop production

Many people think that electromagnetic flowmeter non-contact measurement of the working mode, or that electromagnetic flowmeter on the straight section requirements low, are wrong, this wrong understanding, often at the expense of accuracy.

Extreme in practice, the ultrasonic flowmeter has been able to achieve 0.5% accuracy, its superior many points in the future industry application gradually, of course, there are a lot of people, will protest disadvantages of the ultrasonic flowmeter, so I hope everyone in the selection, to clear their application conditions, and then according to the working condition of choosing appropriate flow meter.Choose the instrument with different precision, only the instrument that meets the actual work requirement of oneself is a good instrument.

Electromagnetic flowmeter brand is numerous, half of its accuracy and price have proportional tendency, ultrasonic flowmeter is also divided into many grades of the brand, the corresponding accuracy and reliability is also very different, so in the choice of instruments, to their actual needs as the basis.
