Multi-Sensor Area Velocity Flow Meter
SIMULATION
Exercises the 4-20mA (0-5V) outputs, digital display and control relays.
Test
Select
Maximum
and press

to simulate maximum Flow, Level and
Velocity and to output 20mA (5V) to the analog channels.
Select
Minimum
and press

to simulate minimum Flow, Level and
Velocity and to output 4mA (0V) to the analog channels.
To simulate an intermediate Flow, Level and Velocity set
Test
to
Actual
and then enter a value for the
Level
and
Velocity
.
The Flow calculation, analog outputs and control relays will respond to
the simulated values.
