  • Page 7: Safety Instructions

    INFORMATION! The manufacturer is not liable for any damage resulting from improper use or use for other than the intended purpose. The ALTOSONIC V12 is an ultrasonic gas flowmeter for high accurate and custody transfer applications. CAUTION! High levels of CO can inhibit the operation of an ultrasonic flowmeter due to its acoustic absorption properties.

    The trajectory of the sound wave is called the acoustic path. A chord is the direct path crossing the pipe from one side to the opposite side. Using reflection, an acoustic path can consist of two or more chords. The name ALTOSONIC V12 is related to its design where 12 chords build 6 acoustic paths.
