Oil and chemical reagents as well as compressed air, saturated vapor and superheated vapor, natural gas flow measurement of various media and can be used as a flow transmitter in automated control systems.

Electromagnetic flow meters offer several advantages, making them a popular choice in various industrial applications. Here are some of the key advantages of electromagnetic flow meters:

When the user chooses the sewage flow meter and the tap water flow meter, I believe that many users will think of the ultrasonic flow meter, so why is the ultrasonic flow meter so popular?

When the ultrasonic flowmeter experiences unstable signals and inaccurate readings during operation, many users tend to think that there is a problem with the ultrasonic flowmeter sensor. However, this is not always the case. Today, Aister Instruments, a flowmeter manufacturer, will explain to you the reasons why the ultrasonic flowmeter sensor is good but the flow rate is low or there is no flow rate fault.

In modern industrial production, efficient and accurate flow measurement is the key to ensuring process stability and improving energy efficiency management. Vortex flowmeters, with their advantages of simple structure, high reliability and wide application range, have become the “main force” in flow monitoring in industries such as petrochemicals, energy and power, metallurgy and pharmaceuticals, providing solid support for the intelligent upgrade of industry.

Installing electromagnetic flowmeters correctly is essential for ensuring accurate and reliable flow measurement. Here are some precautions to consider when installing electromagnetic flowmeters:

Handheld ultrasonic flowmeters are widely used in industries such as water supply, heating, water conservancy, metallurgy, chemical engineering, and machinery. They can be used for production monitoring, flow comparison, temporary detection, and flow inspection, and are commonly used instruments for flow detection.

According to the composition of the sensor and the converter, the electromagnetic flowmeter can be divided into two types: separation type and one type. The separation type is to set the sensor and the converter independently, and the middle is connected with a cable, so the cable length is limited by the conductivity of the measured current body. One type is the sensor and converter as a whole set, so it is related to the fluid temperature and the ambient temperature, compared with the separation type, the applicable temperature range will be limited.
