9. ible transportation company and Netafim USA 4 OCTAVE ULTRASONIC WATER METER INSTALLATION amp USER GUIDE OPERATION e 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 e The Octave is a battery powered precision water meter designed for linear bidirectional flow measurement of water e Flow measurement values can be transferred through the standard digital or analog output SPECIFICATIONS e The Octave display can be set up for a wide range of outputs e Maximum Working Pressure 175 psi Liquid Temperature 32 to 122 F Precision Class ISO 4064 rev 2005 Accuracy Class 2 Configuration Compact display is built into the unit e Power Source 2 D size Lithium Batteries not serviceable by user Environmental Protection IP 68 Ambient operation temperature for display 13 to 131 F 25 to 55 C Display Units Multi line programmable 9 digit LCD display e Volume Display Options 1 Net Forward less Reverse 2 Forwar
