The new first wave detection suited for ultrasonic water meters .The programmable offset range of the comparator is increased to ± 35 mV and the offset is automatically set back to zero after the first wave detection. Measuring the first wave gives the user an indication of the strength of the received signal. It can be used for adopting the system to longterm signal attenuation or for bubble detection.
Measure Mode 1:
1)Two channels with typical 90ps resolution
2)One channel double resolution with typical 45ps
3)Measurement range 3.5 ns (0 ns) to 2.5μs
4)20ns pulse pair resolution, 4 fold multi-hit
Measure Mode 2:
1)One channel with typical 90ps resolution
2)double resolution with 37ps,quad resolution with 19ps
3)Measurement range 500nsto4ms( XIN with 4MHz)
4)3 fold multi-hit capability with automatic processing of all 3 data
