1. Measurement Principle of Metal Float Flow Meter

The metal tube float flow meter is a variable area flow side balance meter, which means that in the vertical measuring tube of the flow meter, when the operating fluid flows upward through the tube. The float moves upward, and at a certain position, the lift acting on the float reaches equilibrium with the weight of the floats obstruction. At this point, the circulation gap area between the float and the orifice plate (or cone tube) remains constant. The annular gap area is proportional to the rising height of the float, that is, a certain height of the float represents the size of the flow rate. When the float moves up and down, the position is transmitted to the external indicator in the form of magnetic coupling, so that the pointer of the indicator follows the movement of the float, and with the help of the cam plate, the pointer linearly indicates the size of the flow value. The electric remote transmission type accurately converts the flow rate value into a standard signal of 0-10mA or 4-20mA through an angular displacement sensor and an electric transmission circuit while the pointer indicates the flow rate on site.

2. What is LZZ flowmeter? What is the principle and structure? LZZ is a metal tube rotor flowmeter. Structure: LZZ metal tube rotor flowmeter. The metal tube float flowmeter mainly consists of three parts: a. Indicator buried crack and (intelligent indicator, on-site indicator) b. Float c. Cone measuring chamber. Principle: When the measured medium of LZZ metal tube rotor flowmeter passes through the cone measuring tube from bottom to top, a differential pressure is generated at the upper and lower ends of the float to form an upward force. When the upward force exerted on the float is greater than the weight of the float immersed in the fluid, the float rises, and the curvature area of the annular gap increases accordingly. The fluid flow velocity at the annular gap immediately decreases, and the differential pressure between the upper and lower ends of the float decreases. The upward force acting on the float also decreases until the upward force equals the weight of the float immersed in the fluid, and the float stabilizes at a certain height. The height of the float position corresponds to the flow rate of the measured medium. The float is equipped with magnetic steel, and when the float moves up and down with the medium, the magnetic field changes with the movement of the float.

3. Principle and Function of Metal Tube Float Flow Meter

The principle of metal tube float flow meter is based on the pressure difference generated when the fluid passes through the gap between the float and the measuring tube to balance the weight of the float. Its main function is to measure the instantaneous flow rate and cumulative flow rate of gases or liquids.. The reading of a float flowmeter is usually checked on an indicator or signal transmitter. Principle: When a fluid passes through a metal measuring tube, the float is balanced by gravity, buoyancy, and the vertical thrust of the fluid on the float. The rising height of the float is directly proportional to the fluid flow rate, so the position of the float directly reflects the flow rate of the measured medium. Function: Measuring instantaneous flow rate: Float flowmeter can intuitively measure the instantaneous flow rate of gas or liquid, and read it through electronic digital display or
