System-on-Chip Solution for Ultrasonic Flow Metering
The TDC-GP30 is the next generation in ams (previously acam) development for Ultrasonic Flow Converters. It drastically simplifies the design of ultrasonic heat and water meters and is the necessary step for compact energy-saving ultrasonic water meters. The ultra-low-current capabilities allow the use of standard 2/3 AA or AA lithium batteries at 6-8Hz measuring frequency as needed for water meter. The GP30 is a system-on-chip that allows you to perform all measurement tasks in one IC.
