Home / Products / Flow Sensing / Ultrasonic Flow Converters / TDC-GP30 Ultrasonic Flow Converter

Features

  • High performance and ultra-low power 32-Bit CPU with 4k NVRAM and 4k ROM
  • Up to 31 multi-hits for flow measurement yield the highest accuracy
  • Advanced high-precision analog part
  • Transducers can be connected directly to GP30, no external components required
  • Amplitude measurements of receiving signal for secure bubble, aging and empty spool piece detection
  • High update rates with very low power consumption (e.g. 6 µA@8Hz)

 

Benefits

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

Product name
Ultrasonic Flow Sensing Module
Description

The flow sensing module IA-UWM-2-GP30-DN20 from Chinese metering equipment manufacturer iESLabs, is based on the TDC-GP30 ultrasonic flow sensor chip. The TDC-GP30 performs precise timing measurements and calculates accurate flow measurements based on the transmission time of ultrasonic signals in moving water. The IA-UWM-2-GP30-DN20 ultrasonic flow sensor unit is comprised of ultrasonic transducers and a spool piece assembled alongside a TDC-GP30 in a robust enclosure. The release of the module provides meter manufacturers with a ready-made, calibrated ultrasonic sensing unit which offers proven flow measurement performance, saving them the need to develop their own ultrasonic sen-sor technology and reducing the time to market for new ultrasonic water meter products.
