OPERATION
• The Octave's measurement method is based on an ultrasonic, transit-time, dual-beam sensors that determines the
length of time it takes an ultrasonic wave to travel the distance between the two sensors located in the meter's
body. The sensors function as both sender and receiver, each one alternating these functions so that the ultrasonic
wave travels both with and against the direction of the flow. Because the ultrasonic wave travels slower against the
flow than with the flow, the time difference of the two waves allows the meter to determine the flow rate.
• The Octave is a battery-powered precision water meter designed for linear, bidirectional flow measurement of water.
• Flow measurement values can be transferred through an output module.
• The Octave display can be set up for a wide range of outputs.
