COUNTERS
The digital I/O card can be fitted with six sixteen bit counters. Each of these
counts up to 65535 and then wraps around to zero.
They can be read with constant time intervals resulting in measurements values
representing pulses per delta-t.
Flowmeters output a set number of pulses per given unit of volume. They are
therefore an excellent example of how the counters can be used to measure
flow.
2.1
Reset mode
Reset mode will reset (or zero) the counters as soon as their value is taken care
of. This value is then treated as if it were an ordinary analog measurement.
(Litres per second maybe ?)
2.2
Normal mode
Normal (or accumulating) mode does not reset the counters when they have
been read. Values that are taken with this mode are in fact the time-integral of
the transducer output.
This mode is not supported by the software. See the command manual for
further information on this mode.
