The SoC TDC-GP30 significantly simplifies electronics for ultrasonic water meters.

It is highly accurate and extremely energy efficient; the TDC-GP30 heralds a new era for a full static measurement method in ultrasonic flow measurement. The integrated 32-bit μP performs mathematically complex and computationally intensive flow calculations with all the necessary corrections in an extremely power-efficient manner, while the external micro-processor is fully relieved of this task.

TDC-GPC30 is a new member of the UFC (Ultrasonic Flow Converter) family. The design of new ultrasonic flow meters can be greatly simplified and shortened by the TDC-GP30, allowing manufacturers to develop cheaper, more compact and energy efficient ultrasonic meters. The TDC-GP30 is a System-on-Chip solution with extremely low power consumption, which undertakes all the measurement tasks up to the calibrated output value.
