MS1022 Datasheet | Ruimeng

DESCRIPTION The MS1022 is high-precision time measurement circuit, which integrates analog parator, analog switch and schmitt trigger and so on, thus greatly simplifying peripherals. In addition, the first wave detection function makes the MS1022 improve the anti-interference ability. According to read the relative width of first return pulse, user can get the strength indication of received signal. And by the indication, many fault conditions can be judged, such as ultrasonic transducer fault, increased tube coverings and bubbles in water. One measurement for ultrasonic time difference (forward flow and reverse flow) and data-read can be performed according to mand, which greatly reduces software operation and electricity consumption.
