When selecting differential pressure flow switches for large and medium-sized chiller units, it is necessary to comprehensively consider system characteristics, safety requirements, and equipment compatibility.

The daily maintenance of vortex flowmeters should focus on key aspects such as regular cleaning, pressure coefficient adjustment, component inspection, electrical maintenance, and troubleshooting to ensure measurement accuracy and long-term stable operation of the equipment.

The gas vortex flow meter utilizes the fluid vortex precession effect, integrates automatic temperature and pressure compensation, and is suitable for metering clean and dry gases such as natural gas and compressed air. It is an intelligent velocity flow meter with high accuracy, no mechanical wear, wide range, and easy installation and maintenance.

Metal float flowmeters measure flow rate by observing the positional changes of a float within a tapered tube. Their core principle is variable area flow measurement, which utilizes the balance between the pressure difference generated by the fluid flowing through the annular gap between the float and the tapered tube and the float’s weight to convert the flow rate into a linear relationship with the float’s height.

Metal tube float flowmeters, with their core advantages of simple structure, reliable measurement, and strong adaptability, are indispensable flow measurement instruments in industrial automation process control. They are particularly suitable for measuring small-diameter, low-flow-velocity, and complex media, and are widely used in industries such as petroleum, chemical, pharmaceutical, food, and water treatment.

The core function of the insulation jacket of a metal tube float flowmeter is to maintain the temperature environment required by the process fluid, ensuring that the flowmeter can work normally and accurately under extreme temperature conditions. Specifically, this is manifested in three key functions: preventing the medium from solidifying/crystallizing, preventing the medium from vaporizing/vaporizing, and maintaining the stability of the medium viscosity.

The material of a metal tube float flowmeter directly affects its measurement accuracy, service life, and safety. Selection must be based on the corrosiveness of the medium, temperature, and pressure. Commonly used materials include stainless steel, Hastelloy, titanium, and PTFE lining, each suitable for different operating conditions.

Metal tube float flowmeters, with their high accuracy, wide measuring range, strong adaptability, and reliable stability, have become indispensable flow measurement instruments in industrial automation process control, and are particularly suitable for flow monitoring in harsh environments such as high temperature, high pressure, and corrosive conditions.

Metal float flowmeters measure flow rate by changing the position of the float in a tapered tube. The core principle is variable area flow measurement, which utilizes the pressure difference generated by the fluid passing through the annular gap between the float and the tapered tube and the balance of the float’s weight to convert the flow rate into a linear relationship with the float’s height.
