System Descri ption and Measurement Method
• The OCTAVE’s measurement method is based on an ultrasonic, transit-time, dual-beam sensor which determines
the length of time it takes an ultrasonic sound wave to travel the distance between the two sensors located on the
meter’s body. The two sensors function as both the sender and the receiver, each one alternating these functions
so that the ultrasonic wave travels both with and against the direction of the flow. Since the ultrasonic wave travels
slower against the flow than with the flow, the time difference of two waves traveling with and against the flow leads
to determining the velocity of the water
• The OCTAVE ultrasonic flow meter is a battery-powered precision flow meter designed for linear, bidirectional flow
measurement of water
• Flow measurement values can be transferred through the standard digital or analog output
• The OCTAVE can be set up for a wide range of applications
