Product overview 

The FTS turbine flowmeter is a velocity type flow measurement instrument. The fluid flows through the sensor's enclosure, and the fluid's impulsion gives the blade a driving torque due to a certain angle between the impeller's blade and the flow direction. After overcoming the friction moment and hydraulic resistance, the blade will rotate. Upon achieving the moment equilibrium, the rotate speed will become stable. Under a certain condition, the rotate speed is proportional to the flow rate. The blade is located in the signal detector's (comprised of the permanent magnetic steel and the coil) magnetic field due to the magnetic permeability of the blade. The rotating blade cuts the magnetic line of force and periodically changes the magnetic flux of the coil so that the electrical pulse is induced at both ends of the coil. The signal is amplified and shaped by an amplifier to form a continuous rectangle impulse wave with a certain amplitude which can be far transmitted to the display instrument to show the instantaneous flow rate or total flow of the fluid. Within a certain range of flow, the pulse frequency f is proportional to the instantaneous flow rate Q of the fluid flowing through the sensor. It can be used to measure the volume flow rate of the liquid which is filled with closed tubes and continuously flows. The advanced technology and processing technology is used and the product performance is stable with high precision and multi-structure design, facilitating the user selection. The product is widely used for the industries, such as petroleum, chemical engineering, metallurgy, thermal power generation, lithium battery new energy industry, scientific research, paper making, heating steam and food.
