Procon systems offers hybrid ultrasonic flowmeters from fuji electric. These ultrasonic flowmeters utilise pulse doppler method along with transit time method. They enable measurement of velocity profile directly, resulting in high accuracy. This makes them suitable for undeveloped flow and for short straight pipes. Pulse doppler method requires reflectors in the liquid and is utilised on opaque liquids and is utilised on opaque liquids while transit time method requires ultrasound penetration and is ideal for clean liquids. The new hybrid technology utilises both methods in a complementary fashion, thus enabling a wider range of applications than it is possible now. In addition, either method can be automatically switched to accommodate for varying fluid conditions, such as concentration of particles and/or air bubbles. Features include: automatic switchover function between pulse doppler method utilising ultrasound reflection and transit time method utilising ultrasound penetration; high-accuracy non-intrusive [non-contact] volumetric flow rate measurement of liquid flow in closed pipes; direct measurement of velocity profile in case of pulse doppler method; high speed response; real time monitoring of velocity profile by pc in case of pulse doppler method; and dual-path option that improves performance double.
