C.2.1
Electronics verification using flow simulation mode
Electronics verification can be done by utilizing the internal flow simulation functionality.
This functionality is available as model option code DS1 at the time of order. The
Rosemount 8600D is capable of simulating either a fixed flow rate or a varying flow rate.
The amplitude of the simulated flow signal is based on the minimum required process
density for the given line size and service type. Either type of simulation (fixed or varying)
will effectively disconnect the Rosemount 8600D sensor from the electronics charge
amplifier input (see
) and replace it with the simulated flow signal.
C.2.2
Fixed flow rate simulation
The fixed flow simulation signal can be entered in either percent of range or flow rate in the
current engineering units. The resulting flow rate and/or shedding frequency can be
continuously monitored via a Field Communicator or AMS.
C.2.3
Varying flow rate simulation
The profile of the varying flow simulation signal is a repetitive triangular waveform as
illustrated in
. The minimum and maximum flowrate can be entered in either
percent of range or entered as a flow rate in the current engineering units. The ramp time
can be entered in seconds from a minimum of 0.6 seconds to a maximum of 34951
seconds. The resulting flow rate and/or shedding frequency can be continuously monitored
via a Field Communicator or AMS.
Note
To manually disconnect the sensor for precautionary measures, see
electronics housing on page 77
for details.
