1.Introduce:
Turbine flow meters are devices used to measure the flow of liquids. They are commonly used in industrial and commercial environments where precise measurement of fluid flow is required. These flow meters work by measuring the rotational speed of a turbine or propeller placed in the fluid stream.
Henan Junyuan turbine flowmeter manufacturer specializes in the design, development and production of flow equipment. Advanced technology and engineering principles are used to ensure the instrument is highly accurate, reliable and efficient. We, as a manufacturer, offer a range of flow meters that can be customized to meet the specific needs of our customers.

2. Structural features and working principle:
*Structural features:
The sensor is a thrust type of hard alloy bearing, which not only ensures the accuracy and improves the wear resistance, but also has the advantages of simple structure, strong and easy disassembly.
*Working criteria:
When the fluid flows through the sensor housing, due to the angle between the impeller blades and the flow direction, the fluid blades generate the impact of rotational torque, which overcomes the frictional torque and fluid resistance. After the knife speed is stable, the moment is balanced. Magnetic vane, in the magnetic field of the signal detector (composed of permanent magnets and coils), the rotating blade cuts the line and periodically changes the magnetic flux of the coil, thereby inducing an electric pulse signal coil at the end, and the signal is amplified and shaped by the amplifier to form A continuous rectangular pulse wave with a certain amplitude can be transmitted to the display instrument remotely to display the instantaneous flow or volume of the fluid. Within a certain flow range, the pulse frequency f is proportional to the instantaneous flow Q of the fluid flowing through the sensor, and the flow equation is: 
Type:
f —— pulse frequency (Hz)
k —— he instrument coefficient of sensor 1 / m3, given by the check list. If [1 / L] as the unit
Q— fluid transient flow (working conditions) m3 / h
3600 —— conversion factor
Coefficient of each sensor of the instrument in the calibration certificate will be completed by the manufacturer, set into the display instrument of form a complete set of k value, can show the instantaneous flow and cumulative total.
