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.

This product suits for the following applications:

  • Non-invasive cold water meter
