ماژول درایور فلو متر التراسونیک TDC-GP22

The TDC-GP22 flowmeter driver module is a time-to-digital converter (TDC) used for precision time measurement applications. It is commonly used in applications such as ultrasonic flowmeters, distance measurement, and time-of-flight (ToF) applications.

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 relative pulse width of the first wave gives the user an indication of the strength of the received signal. This can be used for adopting the system to long-term signal attenuation or for bubble detection. The multi-hit data processing and data read-out is simplified compared to TDC-GP21. All in all, the TDC-GP22 is a further improvement and simplification for the design of ultrasonic heat meters and a necessary step for compact ultrasonic water meters.
