LZD Metal Tube Rotameter

Apure LZD Metal Tube Rotameter adopts variable area measurement principle to measure the flow of gas and liquid in various flow directions. Compared with the glass rotor flowmeter, the pressure resistance grade of the flowmeter is improved, and the flow signal can be transmitted and accumulated. Specifications and varieties are complete, including spot indication type, electric transmission type, corrosion resistant type, clamping type, damping type, alarm and explosion-proof type.

Metal tube rotameter, and glass tube float flowmeter working principle is basically the same, are based on the variable area method to measure the flow of fluid. When the fluid flows through the conical metal tube, the float will be subject to the upward thrust of the fluid. As the flow rate increases, the height of the float rising in the tube also increases. By measuring the height of the float inside the tube, the corresponding flow rate value can be derived.

Framework

• Conical metal tube: The material of the conical metal tube is usually stainless steel or other corrosion-resistant materials, selected according to the characteristics of the medium.
• Float: Float is generally made of magnetic material to realize the non-contact signal transmission with the external indicating device.
• Magnetic coupling device: the float position changes into an electrical signal, for remote transmission and display.
• Indicator or Transmitter: Displays or outputs the measured flow value.

Advantages

• Corrosion resistance: The metal tube is available in a wide range of materials and can be adapted to a wide range of corrosive media.
• High-temperature and high-pressure resistance: can be used in high-temperature and high-pressure working conditions.
• Wide measuring range: Can measure gases, liquids and other media.
• Sturdy structure: The metal material has high mechanical strength.
• Remote transmission: Through the magnetic coupling device, it can realize the remote transmission of flow signal.

Applications

• Petrochemical industry: Measure the flow of various petrochemical products.
• Power industry: Measure the flow of boiler feed water, condensate and so on.
• Metallurgical industry: Measure the flow of acid and alkali liquid, high temperature molten metal.
• Food and beverage: Measure the flow of various liquids.
