Ultrasonic Flowmeter
-------------------
Manufacturer: SMC(USA)
Model: ALSONIC-FDSP Series
Introduction:
The ALSONIC-FDSP series is a fixed-mount, transit-time ultrasonic flowmeter with clamp-on transducers for non-invasive liquid flow rate measurement. Our Alsonic-DSP uses patented "fine time measurement technology" where the meter's ultrasonic beams are capable of measuring the fluid velocity at pico-seconds time intervals. This rapid succession of velocity measurements enables accurate, drift-free flow measurement of ultraclean to dirty liquids containing up 30% of solids or gas bubbles. The use of DSP technology enables "Cross Correlation" of ideal signals to cancel extraneous noise and create a three-dimensional cross section of the flow velocity distribution profile of the medium flowing through the pipe.
Using advanced technology available only from SMC, an innovative "cross correlation mode" expands the ALSONIC-FDSP’s measuring capabilities to include applications previously handled only by Doppler meters, such as raw sewage, sludge, slurries and other extremely attenuating multiphase fluids. An optional dual-channel/dual-path model can be configured for a variety of uses including flow measurement in two different pipes, leak detection by measuring at two different locations on the same pipe and dual-path measurement at one location for maximum accuracy.
Features:

- Oscilloscope feature indicating three-dimensional analysis of the flow stream
- Touch-pad key function
- Patented fine Time Measurement Technology
- Data logger functions; includes date, totalizer, and diagnostics.
- Response time < 1 second.
