TDC-GP30-F01 Ultrasonic Flow Converter

Firmware Supported Intelligent Ultrasonic Flow Converter

Block Diagram of the TDC-GP30 Ultrasonic Flow ConverterThe TDC-GP30-F01 includes flow calculation making the TDC-GP30-F01 a complete ultrasonic flow metering solution that dramatically simplifies the design of ultrasonic water and heat meters. This is a vital step for compact energy-saving ultrasonic water meters.

Due to the ultra-low current capabilities, standard 2/3 AA or AA lithium thionyl chloride batteries can be used at 6-8 Hz measuring frequency even in the water meter version. The TDC-GP30-F01 firmware accomplishes the linearization and temperature compensation based on spool piece precise calibration data and completes the system-on-chip approach.

Key Features

  • High performance + ultra-low power 32-Bit CPU with 4k NVRAM and 4k ROM
  • Advanced high-precision analog part
  • 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 (2 Hz) or flow (8 Hz) condition
  • Error handling, bubble detection

Key Benefits

  • Lowest power solution for ultrasonic water meters
  • On-chip firmware allows fastest time-to-market
  • Best measurement performance for leakage detection
