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.

The main reasons for inaccurate measurements by metal tube rotor flowmeters can be summarized into five categories: improper selection, improper installation, changes in media characteristics, equipment failure, and environmental interference. Among these, improper installation and changes in media characteristics are the most common reasons, accounting for more than 70% of actual failures.

Metal tube rotor flowmeters have core advantages in wastewater treatment applications, such as accurate measurement, strong corrosion resistance, and easy installation. They are particularly suitable for treating wastewater environments containing impurities, with low flow rates, and low pressure, and can effectively improve wastewater treatment efficiency and management level.

The installation of metal tube rotor flowmeters must strictly follow three core principles: vertical installation, fluid from bottom to top, and straight pipe sections meeting standards, to ensure measurement accuracy and long-term stable operation.

Metal tube rotor flowmeters (also known as metal float flowmeters) employ the variable area measurement principle, relying on the change in the float’s position within a tapered tube to directly reflect the flow rate. Features: simple structure, wide applicability, resistance to high pressure and high temperature, especially suitable for measuring small-diameter, low-velocity media.

Metal tube rotor flowmeters are flow measurement instruments based on the variable area principle, capable of monitoring small to medium flow rates of liquids, gases, and steam. They measure flow rate by the change in the position of a float within a tapered tube, and transmit the signal via magnetic coupling. Features include: compact structure, wide range ratio (10:1), and easy installation.
