ULTRASONIC FLOW CONVERTERS OVERVIEW

Ultrasonic flow converters for heat, water and gas have recently become more and more popular. Since the beginning, ScioSense (previously acam) TDC products successfully solved the time-of-flight measurement task in those T applications. With the UFC family PMT provides solutions that extend the functionality of pure time measurement. The flow measurement part of the electronics can be designed in a very compact manner as the main elements of the analog frontend like comparator and temperature measurement are already integrated into the UFC.

The term time-to-digital converter is used when talking about time interval measurements in the range of 1 nanosecond down to the picosecond range. The first TDCs have been developed for scientific and research purposes. They have been realized as a combination of time-to-analog (TAC) and analog-to-digital (ADC) converter. A sophisticated design of the TAC together with limitations to update rate or multihit capability make these solutions inattractive for industrial applications.
