Description

TDC-GP30-F01 Ultrasonic Flow Converter Firmware supported intelligent ultrasonic flow converter Features - High performance and ultra-low power 32-bit CPU - Advanced high-precision analog part - Transducers can be connected directly to GP30, no external components required - Firmware for calculation of flow, volume and temperature, including linearization and two-point calibration - Firmware adopts automatically to zero flow (2Hz) or flow (8Hz) condition Error handling, bubble detection Benefits - Lowest power solution for ultrasonic water meters - On-chip firmware allows fastest time-to-market - Best measurement performance for leakage detection Product parameters Analog Frontend: Yes First Wave Detection: Yes Amplitude Measurement: Yes Number of Hits: 31 Resolution [ps]: 11 Operating Supply Range: 2.5 to 3.6 Interface: SPI, UART, Pulse CPU: 32-bit Firmware: Volume, flow, and temperature calculation Memory: 4k NVRAM, 4k ROM GPIO: 6 Ambient Temperature Range [°C]: -40 to +125 Package: QFN32, QFN40 General Description TDC-GP30-F01 is a complete ultrasonic flow metering solution, including the flow calculation. 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 thionyl chloride batteries at 6-8 Hz measuring frequency even in the water meter version. The TDC-GP30-F01 firmware does the linearization and temperature compensation based on spool piece specific calibration data and completes the system-on-chip approach.
