Ultrasonic Flow Converters

TDC-GP30-F01 ULTRASONIC FLOW CONVERTER

Firmware Supported Intelligent Ultrasonic Flow Converter

The 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.

TDC-GP30-F01 – Ultrasonic flow converters
