The OMEGA ® FTB600B Series Flowmeters feature an infrared, electro-optical transmitter and receiver
molded into the flowmeter’s body, along with two miniature circuit boards to provide voltage
stabilization and automatic IR output level control. The FTB600B automatically compensates IR light
intensity for varying fluid opacity levels to insure a strong square wave output signal. The flowmeter
is suitable for clear, transparent and translucent fluids which must transmit infrared light. (Note:
Not suitable for use with red liquids).
The design of the FTB600B inherently bleeds off entrained gas, thereby improving overall accuracy.
This flowmeter can be easily mounted into any position for greater system design flexibility, also
saving time and installation costs. A strainer is included in models FTB602B through FT606B.
