  • Page 17: Description

    Description Overview The SONO 3500 CT ultrasonic flowmeter systems consist of a sensor and a transmitter. The transmitter is type-approved with the custody transfer (CT) approval for use in energy metering systems. The transmitter is designed to measure flow water applications.

  • Page 18: Features

    ● Two digital outputs for volume pulse or alarm Applications The main application for the type-approved SONO 3500 CT flowmeters is measurement of water flow in district heating plants, local networks, boiler stations, substations, chiller plants, irrigations plants, and other general water applications.

  • Page 19: Principle Of Operation

    SONO 3500 CT flowmeters In SONO 3500 CT flowmeters the ultrasonic transducers are placed at an angle θ in relation to the pipe axis. The transducers function as transmitters and receivers of the ultrasonic signals.
  • Page 20 Description 3.5 Principle of operation Figure 3-2 Measuring principle The ultrasonic signal is sent directly between the transducers. The advantage gained sending signals from point to point is an extremely good signal strength. SONO 3500 CT Operating Instructions, 07/2019, VI.SH.P2.02...
