The FLSC-AMP-A Signal Conditioner will amplify low level signals from magnetic pick-up sensors, such as a
turbine meter or paddlewheel sensor, to an amplified high level square wave pulse output proportional in
amplitude to the power supply powering the module. This output will drive any OMEGA®flow ratemeter,
counter, controller or pulse input data acquisition board.
