Jaime If you have the motor run status of the pump that supplies the flow meter available in your DCS, you can connect this boolean to the KSCALE parameter of your AIN block. When the pump is running, KSCALE=1, when the pump is off, KSCALE=0, and the output of the AIN block will be zero. -Brian Bates. |---------+----------------------------> | | "Jaime Claramunt | | | R.
