All Plastic Flow Sensors for Low to Medium Flows

Item# FTB601B

All Plastic Flow Sensors for Low to Medium Flows All Plastic Flow Sensors for Low to Medium Flows
The OMEGA™ FTB600B Series flow meters feature an infrared, electro-optical transmitter and receiver molded into the flow meter’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.
