    The LD301 includes an internal feature to enable and disable the Linearization Table. Totalization Configuration When the LD301 works in flow applications it is often desirable to totalize the flow in order to know the accumulated volume or mass that has flown through the pipe/channel.

  • Page 42: Pid Controller Configuration

    As a PID Controller, the LD301 may run a PID type control algorithm, where its 4 to 20 mA will represent the status of the Manipulated variable (MV). In such a mode, output is 4 mA when the MV = 0% and 20 mA when MV= 100%.
