CVF intelligent vortex flow sensor is a new type of pressure detecting vortex flow sensor using piezoelectric crystal as detecting element. Wide range ratio, high precision, small pressure loss, good medium versatility. Because the detection probe used by the sensor is installed separately from the vortex generator, and the high-temperature piezoelectric wafer is not in contact with the medium, the instrument has the characteristics of simple structure, good versatility and high stability. The CVF intelligent vortex flow sensor can be used to detect and measure the flow of various gases, liquids and vapors.
