Turbine flow meter It consists of a turbine flow sensor and a display instrument. It is one of the ideal flow meters for liquid measurement. The turbine flow meter features a simple structure, high accuracy, and convenient installation and maintenance. The product is widely used in fields such as petroleum, chemical industry, metallurgy, water supply, papermaking, environmental protection, and food. It is suitable for corrosion measurement of stainless steel 1cr18ni9ti, 2cr13, alumina al2o3, and hard alloys in closed pipelines, without fibers, particles, and other impurities in the liquid. When used with display instruments with special functions, the turbine flow meter can achieve automatic quantitative control, over-limit alarm, and other purposes.

1. Features of the turbine flow meter:

1. The sensor uses a hard alloy bearing thrust type, which ensures accuracy and improves wear resistance.

2. Turbine flow meter The structure is simple, sturdy, and easy to disassemble and assemble.

3. Wide measurement range with low lower limit speed.

4. Low pressure loss, good repeatability, and high accuracy.

5. The turbine flow meter has strong electromagnetic interference resistance and vibration resistance.

2. Working principle of the turbine flow meter:

The fluid flows through the sensor and the housing. Due to the angle between the blades of the impeller and the flow direction, the fluid's impact generates a torque that overcomes the friction and flow resistance, allowing the blades to rotate. Once the torque reaches equilibrium, the rotational speed stabilizes under certain conditions. Turbine flow meter The rotational speed is proportional to the flow rate. Since the working blades have magnetic properties, they are in a magnetic field that acts as a detector (composed of permanent magnets and coil structures). The rotating blades cut through the magnetic field lines, periodically changing the magnetic flux in the coils, which induces electrical pulse signals at both ends of the coils. These signals are amplified and shaped into continuous rectangular pulse waves of a certain amplitude, which are transmitted to the display instrument to show the instantaneous flow rate and cumulative amount of the fluid.
