Where fs
max
is the maximum full scale value corresponding to the sensor, equal to a 10 m/sec liquid
speed. The units of measure are shown as appear on the display. The British and American units
are diversified by using capital and small characters. Available units of mass and volume:
When a mass unit of measure is set, the specific gravity function is automatically enabled by the
system. The units of measure of time may be chosen among the values: s=second, m=minute,
h=hour, d=day.
(POS. 2.3) Measure unit and number decimal totalizers
[MU.tot:dm³X.XXX]
Setting the unit of measure and number of decimals for visualized the totalizers or the volumes to
batch. For set the unit of measure, position the cursor on field of the actual unit of measure; to set
the type of unit, position the cursor on the blank space between the unit of measure and the
numeric value; to set the number of decimal totalizers position the cursor on numeric field and
choose one of the possible combinations: 1000-01.00-001.0-00001.
(POS. 2.4-5) Pulse value output 1-2 and unit of measure of tot. [Imp1-2=
dm³ X.XXXXX]
Setting of the pulse volume corresponding to output 1-2 and of the totalizers measure units. There
are three fields to fill in to set this parameter, from left to right: 1) measure unit, 2) unit type and
3) numeric value. The selection is performed by positioning the cursor on the field to be modified.
To change the unit type (metric, British or American, mass or volume) just position the cursor on
the blank space between the measure unit and the numeric value. When the nominal diameter is
set to zero it is possible to modify only the numeric field since the measure unit stays at meter (m)
or feet (ft). The possible measure units are those above described
(POS. 2.6-7) Pulse duration on output 1-2
[Tpul1-2=msXXXX.XX]
Setting of the duration of the pulse generated on output 1-2. Its value is expressed in milliseconds
and has to be between 0.4 and 9999.99. When the high frequency output is present, then the
minimum value can go down to 0.04 milliseconds.
ATTENTION: since the instrument cannot detect which type of device it is connected to, it is up to
the user to verify the set pulse duration is compatible with the external device processing such
pulses. If, for example, an electro-mechanical pulse counter is connected, then two kind of
problems may occur: if the pulse is too long than the coil may burn or, if it is too short, the counter
may not be able to count and eventually even cause the damaging of the output itself.
