    Chapter 1. General installation instructions Chapter 1. General installation instructions Introduction Thank you for purchasing the AT600 ultrasonic flow meter. The AT600 is a clamp-on ultrasonic flow meter for the measurement of liquid products. It is designed for the industrial applications, including water, wastewater, steel, campus energy, and others.

  • Page 12: Theory Of Operation

    Chapter 1. General installation instructions Theory of operation The AT600 flow meter uses a procedure called transit-time flow measurement. In this method, two transducers, which are in acoustic communication with each other, serve as both ultrasonic signal generators and receivers. That is, the second transducer can receive ultrasonic signals transmitted by the first transducer and vice versa.
