Operation
4.1.3 Pulse output test
Pulse Output Test is a fixed frequency mode test that checks the integrity of the pulse loop. It
tests that all connections are good and that the pulse output is running on the loop.
4.1.4 Flow simulation
Flow Simulation enables you to check the electronics functionality. This can be verified with
either the Flow Simulation Internal or Flow Simulation External method. PV must be Volume
Flow, Velocity Flow, or Mass Flow before Flow Simulation can be used.
PV
Shows the flow value in current engineering units for the flow simulation.
Shedding frequency
Shows the shedding frequency for the flow simulation.
Configure flow simulation
Allows you to configure your flow simulation (internal or external).
Simulate flow internal
When licensed, the simulate flow internal function will automatically electronically disconnect
the sensor and enable you to configure the internal flow simulation (fixed or varying).
Fixed flow
The fixed flow simulation signal can be entered in either a percent of range or flow rate in current
engineering units. This simulation locks the Vortex in to the specific flow rate entered.
Varying flow
The minimum and maximum flowrate can be entered in either percent of range or as a flow rate
in current engineering units. The ramp time can be entered in seconds from a minimum of 0.6
seconds to a maximum of 34951 seconds. This simulation causes the Vortex meter to
continuously ramp from the minimum entered rate to the maximum entered rate and back over
the ramp time.
