1. Turbine flowmeter
Turbine flowmeter is a speed type flow instrument with high measurement accuracy, fast response, and high pressure resistance, which is widely used in industrial production.
1. Structure of Turbine Flow Meter The turbine flow meter is mainly composed of a turbine, a guide vane, a magneto electric induction converter, a housing, and a preamplifier.
. Turbine: Made of stainless steel material with high magnetic permeability and placed in ball bearings with low friction. The turbine core is equipped with spiral blades, and fluid acts on the blades to rotate them. Guide vane: composed of a guide ring and a guide seat, it allows the fluid to reach the front guide of the turbine, avoiding changes in the angle of action between the fluid spin and the turbine blades, and ensuring instrument accuracy. The guide vane is also equipped with ball bearings to support the turbine. Magnetoelectric induction converter: composed of coils and magnetic steel, it converts the rotational speed of the blades into corresponding electrical signals, which are supplied to the preamplifier for amplification. Shell: Made of non-magnetic stainless steel, used to fix and protect internal components, and connected to fluid pipelines. Pre amplifier: amplifies the weak electrical signal output by the magneto electric induction converter for remote transmission.2. Working principle of turbine flowmeter: When the fluid passes through the gap between the turbine blades and the pipeline, the force generated by the pressure difference before and after the blades pushes the blades, causing the turbine to rotate.
. At the same time as the turbine rotates, the highly magnetic turbine periodically scans the mag
2. Working principle of turbine flowmeter
The working principle of turbine flowmeter is based on fluid dynamics and electromagnetic induction principles. Flow measurement is achieved by measuring the impeller speed. The specific process is as follows
1. Fluid drives the impeller to rotate. After entering the sensor housing of the turbine flowmeter, the fluid impacts the impeller blades.
. Due to the fixed angle between the blades and the flow direction of the fluid, the impulse of the fluid generates a rotational torque on the blades. The impeller begins to rotate after overcoming the frictional torque and fluid resistance, and when the torque reaches equilibrium, the impeller speed tends to stabilize. Key relationship: Under specific conditions (such as stable fluid viscosity and density), the impeller speed is directly proportional to the fluid flow velocity.
