Signet 3350/3550 Ultrasonic Flowmeter
3-3350.090
Rev. A 11/05
3-3350.090
1. Description
The Signet 3350/3550 Ultrasonic Flowmeter uses transit-time technology to deliver
accurate flow rate and totalizer information with no direct fluid contact.
Originally used for temporary installations and periodic flow rate validation, today these
ruggedized instruments are perfectly suited to applications where pipes cannot be
penetrated, or where the fluid medium is hazardous or easily contaminated.
The clamp-on sensors are easy to install, without interrupting the process stream. Simply
enter the pipe parameters and the application preferences; the 3550 will provide stable and accurate data that is tailored
by you, for your unique requirements.
The Ultrasonic Flowmeter is programmable via the front panel keypad. Select display menu instructions in English,
French, Spanish, German or Japanese on a 2-line, backlit LCD.
