CJMCU-22 TDC-GP22 2-Channel Time Digital Converter Sensor Board Ultrasonic Flow Converter Module

TDC-GP22 is next generation's upgrade for TDC-GP21. Feature: Compatible upgrade of TDC-GP21, with extended functionality. Especially the new first-wave detection capability makes the TDC-GP22 perfectly suited for ultrasonic water meters with their high dynamics. 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 are simplified compared to TDC-GP21. All in all, the TDC-GP22 is further improvement and simplification for the design of ultrasonic heat meters and a necessary step for compact ultrasonic water meters. Package included: 1 x TDC-GP22 Converter Module with pins
