AMP. Figure l-l. Block Diagram The basic operation of the system is as follows: The frequency signal from the flowmeter is connected to the FTB500 with a twisted pair shielded cable. The signal enters through the SENSITIVITY control which is used to reject unwanted noise by raising the trigger threshold above the background noise present.
FTB500 Series of meters establish a linear response after an initial offset correction when operating at a constant viscosity. 3 FTBSOO flowmeter are shown in Figures l-2 and 1-3.
