Units:
A drop down menu offers the choice of - Litres, ml,
gms, kg, US gallon, Imperial gallon or Custom units i.e. blank
Note that the Custom Units setting will be equivalent to Litres if no
modifications are made to scale factor.
Rate (units per):
This is the time base for the flow rate and
has the option of Second, Minute or Hour
Scale Factor
Adjustment: This allows the user to adjust or
tune the calibration flow value if required.
Density:
The flowmeter is fundamentally a volumetric device,
but a density figure can be entered here if one of the mass
units is selected. Caution must be used however, as there is
no temperature/density correction.
Cut Off:
Flow values below this level will be set to zero.
Reed Relay:
Use when connecting a Reed relay flow
meter.
When ticked this provides an additional extended filter in
which a logic high signal must be high for at least 560μs
before it is propagated; whereas a logic zero is propagated
immediately. This is intended for a circuit in which the reed
relay switches to ground with a pull-up resistor.
Detection: Pulse detection can be chosen for Rising edge;
Falling edge or Both edges.
"Both edge" detection measures both the rising and falling
edges
