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
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.
Simulate Flow External
Simulate flow external allows you to disconnect the sensor electronically so
an external frequency source can be used to test and verify the electronics.
Enable Normal Flow
Enable normal flow allows you to exit the flow simulation mode (internal or
external) and return to normal operation mode. Enabled Normal Flow must be
activated after any simulation is run. Failure to enable normal flow will leave
the Vortex in simulation mode.
