Turbine Insertion Flow Meter Working Principle
The plug-in turbine flowmeter is a new domestic velocity flowmeter. The turbine head, detection coil, etc. are designed as a combined plug-in. Because of its small size, the installation hole is also small. Therefore, a ball valve can be used to solve the problem of closing the installation hole.
More ingeniously, the insertion rod is made into a trapezoidal screw. When you need to remove it, you don’t need to stop the water. You can first rotate the trapezoidal screw to gradually raise the turbine head. After passing the upper ball valve, rotate the handle of the ball valve to close the pipeline. You can continue to spin up the turbine until it is removed. After installation and reset, proceed in reverse order. The same can be achieved without stopping the water.
The impeller inserted into the detection head of the plug-in turbine flowmeter is rotated by the fluid. The magnetic resistance of the magnetic circuit of the detection coil is periodically changed. The magnetic flux in the detection coil is periodically changed. Therefore, electric pulses are induced in the detection coil. Flow signal. The frequency f (times/second) of this signal is proportional to the volumetric flow Q (m3l second) flowing through the pipeline. The proportional coefficient is the meter coefficient K of the sensor, so f=K”Q.
The electrical pulse signal is amplified by the preamplifier and sent to the secondary instrument. Its waveform is rectangular pulse. After further enlargement and shaping, it is divided into two ways.
Send coefficient conversion circuit all the way. Then the power amplifier is sent to the totalizer. Obtain the cumulative volume flow. The other way sends the frequency dividing circuit. Then output 0~10mA (or 4~20mA) current signal through frequency/current conversion. At the same time, the instantaneous flow rate is displayed on the secondary meter.

Simply put. The turbine flow meter has a turbine. It needs to be installed in the fluid pipeline when in use, and both ends are supported by bearings.
When the fluid passes through the turbine. The fluid hits the turbine blades. Drive the rotation of the turbine blades. The flow rate is measured indirectly through the angular velocity of the turbine blades. The method used is that the angular velocity of the blades is proportional to the fluid velocity.
