描述 Description

TDC-GP30 is the next step in ultrasonic flow metering. 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 is a system on chip approach that allows you to perform all measurement tasks in one IC.

特性 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)

應(yīng)用 Application

? Ultrasonic water meters

? Ultrasonic heat meters

? Ultrasonic gas meters

? Industrial flow indicators
