2.1
SYSTEM OPERATI ON
The D-1401 and D-1402 Display Module LCD display shows the flow rate as a
number representing the frequency output signal, in Hertz, from the flow meter.
The D-1401 Display Module shows the frequency output signal of the single turbine
from the F-1100.
The D-1402 Display Module shows the averaged output from
both turbines. This system also has the capability of
displaying the individual output from the top or bottom
turbine by using the selection switches on the Display
Module.
This frequency output is then converted to gallons per minute
for the pipe size being measured via the laminated
conversion chart included with the system.
Please contact Onicon to obtain conversion factors for any
pipe sizes not listed on the chart, or if you require a flow rate
unit of measure other than gallons or liters.
