Choose flow meter, need to know what?

The threaded liquid turbine flowmeter is a kind of precision flow measuring instrument, which can be used to measure the flow and total amount of liquid with the corresponding flow integrating instrument. Widely used in petroleum, chemical industry, metallurgy, scientific research and other fields of measurement, control system. Threaded liquid turbine flowmeter sensors with sanitary fittings can be used in the pharmaceutical industry.

Electromagnetic flowmeters are used to measure the volume flow of industrial liquids and there are many media in industrial liquids, electromagnetic flowmeters are often used to measure the flow of conductive media.

Vortex flowmeter is a velocity flowmeter, which measures the volume flow rate in the working state.

With the speeding up of urbanization process in our country, environmental pollution is increasingly serious. Because in sewage treatment, it is necessary to analyze and control the discharged sewage, additives, sludge, etc., so the flow measurement is very important. Among the many flowmeter products used for sewage measurement, electromagnetic flowmeter measurement accuracy is higher.

Vortex flowmeter is a kind of instrument device to measure the flow of pipeline fluid, and it works by the principle of velocity vortex. Vortex flowmeter has two kinds of volume and mass flow measurement, which can be selected according to the situation of the field.

The measuring channel of the electromagnetic flowmeter is a smooth straight pipe of an unimpeded flow detector, which is not easy to block and is suitable for measuring liquid-solid two-phase fluids containing solid particles or fibers, such as paper pulp, coal water pulp, mineral pulp, mud and sewage.

ultrasonic flow meters find applications in HVAC systems for measuring the flow of heating or cooling fluids. Their non-intrusive installation makes them an ideal choice for retrofits and upgrades to existing systems, allowing for accurate measurement without disrupting the infrastructure. This application contributes to the efficient operation of HVAC systems, optimizing energy consumption and ensuring optimal environmental conditions in buildings.

In the process of using the steam flowmeter, we may encounter some minor failures, do not panic after the problem, find out how to deal with is the key. The following introduces several common faults of steam flowmeters and their solutions.

Correction methods for ultrasonic flowmeters are essential to ensure accurate and reliable measurements. Here are some specific correction methods commonly used in practice:

Ultrasonic flowmeters are instruments that measure flow by detecting the effect of fluid flow on an ultrasonic beam (or ultrasonic pulse). The ultrasonic flowmeter is mainly composed of an ultrasonic transducer (or an ultrasonic flow sensor composed of a transducer and a measuring tube) and a transducer mounted on the measuring pipe.

The gas turbine flowmeter is a flow measurement instrument designed based on the principle that the turbine speed is proportional to the fluid flow velocity. It features high measurement accuracy, fast response speed and wide range ratio. It calculates the gas flow rate by detecting the rotation frequency of turbine blades and is widely used in fields such as industrial process control, energy measurement and environmental protection.

Ultrasonic flowmeters are instruments that measure flow by detecting the effect of fluid flow on an ultrasonic beam (or ultrasonic pulse). The ultrasonic flowmeter is mainly composed of an ultrasonic transducer (or an ultrasonic flow sensor composed of a transducer and a measuring tube) and a transducer mounted on the measuring pipe.

Electromagnetic flowmeter plays a multi-faceted role in farmland irrigation, mainly reflected in the following aspects:

Liquid turbine flow meters are devices used to measure the flow of liquids through a pipeline. They operate on the principle of a turbine rotor turning in response to fluid flow. Here are some advantages of liquid turbine flow meters:

Nominal diameter： DN15-DN200mm
Accuracy： 1.0/1.5
Body material: Aluminum alloy, 304 stainless steel
Applicable media: Compressed air, oxygen, nitrogen, carbon dioxide, natural gas, argon, liquefied gas, etc., corrosion, moisture can not be measured, such as chlorine, hydrogen, steam, ammonia.

Usually there is more or less a mixture in the fluid in the measurement of some occasions. In general, in the presence of a small bubbling flow of oil and gas bubbles, it is still able to work normally, but the measurement is a fusion of the volume of oil bubbles, if the proportion of oil and gas rises to have caused a projectile flow, then the electrode may be covered by gas, resulting in the circuit is disconnected, the output shake is more likely to be directly damaged.

electromagnetic flowmeters have emerged as indispensable tools for industries that demand accurate and reliable flow measurements. Their advanced technology, coupled with the ability to operate in diverse environments and handle various conductive liquids, positions them as a preferred choice in applications ranging from water management to chemical processing. As technology continues to evolve, electromagnetic flowmeters are likely to witness further advancements, contributing to increased efficiency and precision in liquid flow measurement across different sectors.
