Detecting Karman vortex with phase demodulation of ultrasonic wave, there is no moving part and the sensor is non-contact type. It improved concussion resistance greatly and realized the wide flow range.
- Because high frequency ultrasonic sensor is used, it is not influenced by mechanical noise such as piping vibrations.
- The detection of vortex from low speed is enabled without being influenced by a sudden temperature change by adopting a double sensor system with double sensitivity.
- The ultrasonic sensor assembly can be detached from the flowmeter housing while the flowmeter is installed in piping. Therefore, bypass line is unnecessary.
- Because zero point and zero cut adjustment are unnecessary, SUS series can be used immediately after installation on site.
- It is realized by the original shape of vortex generation pillar.
