Vortex Flowmeters

The vortex flowmeter is based on the Karman Vortex Street principle, featuring strong anti-vibration capability and excellent high-temperature resistance. The VFD anti-vibration type adopts dual-probe sensor technology, maintaining accurate measurement even under pipeline vibration up to 3g, with a maximum turndown ratio of 1:20. The VFT Enhanced Vortex Flowmeter adopts advanced FFT spectrum analysis for accurate vortex detection in low-flow regions, with a turndown ratio up to 1:40. Features shielded signal chain, built-in surge protection, optimized anti-vibration algorithms, hot-swappable probe (no process fluid contact).

VFD Anti-Vibration Vortex Flowmeter

VFD Anti-Vibration Vortex Flowmeter

The VFD Anti-Vibration Vortex Flowmeter is a high-performance instrument that employs advanced digital signal processing technology, setting it apart from conventional vortex flowmeter measurement approaches. It delivers accurate measurement even under pipe vibration levels of up to 1 g and flow velocities as low as 0.3 m/s, making it specifically suited to demanding operating environments.

VFT Enhanced Vortex Flowmeter

VFT Enhanced Vortex Flowmeter

The VFT Enhanced Vortex Flowmeter employs advanced signal processing technology based on FFT spectrum analysis to reliably detect vortex signals in the low-flow, small-signal range, achieving a turndown ratio of up to 1:40. It features a shielded signal chain design, built-in surge protection, and an optimized anti-vibration algorithm. The non-wetted probe design allows for online replacement.
