Transit Time DSP Area-Velocity Meter for Open Channels, ALSONIC-AVM
The ALSONIC-AVM may be used in rectangular, circular, trapezoidal or other shaped channels. Since the transducers create almost no restriction, virtually no head loss is created. The advanced DSP-based flow computer with cross-correlation and FFT technology allows this system to work in the most difficult applications, including those involving liquids with high concentrations of suspended solids & air or a large noise component.
- Colour graphic LCD display 128×64 for flow rate, total flow & signal shape
- 32 Mbyte datalogger; up to 200,000 data fields
- No-moving-parts design creates no pressure loss
- Velocities from 0.03 ~ 40 feet/sec (0.01 ~ ± 12 m/s)
- Any liquids containing ≤ 30% suspended solids, including waste water
- High open-channel accuracy; ±2.0% of reading
- Oscilloscope function for diagnostics
- AR (Anti-Round) Mode (patent pending)
- Fine Time Measurement Technology (Patented)
- Data logger function; includes date, totalizer, diagnostics
- Response time less than 1 second
