Smart Control Turbine Flow Meter Simple Structure High Precision
Turbine Flow Meter Working Principle
When the measured fluid flows through the sensor, under the action of the fluid, the impeller is forced to rotate, and its rotational speed is proportional to the average flow velocity of the pipeline, and the rotation of the impeller periodically changes the reluctance value of the magnetoelectric converter. The magnetic flux in the detection coil changes periodically, generate a periodic induced potential, that is, an electrical pulse signal, which is amplified by an amplifier and sent to the display instrument for display.
Turbine Flow Meter Design Feature
◎It is suitable for high pressure measurement, and there is no need to open holes on the meter body, and it is easy to make a high pressure meter;
◎There are many types of special sensors, which can be designed into various special sensors according to the special needs of users, such as low temperature type, bidirectional type, downhole type, special type for sand mixing, etc.;
◎It can be made into a plug-in type, suitable for large-caliber measurement, with small pressure loss, low price, continuous flow and extraction, and convenient installation and maintenance.
