max
is the maximum full scale value corresponding to the sensor, equal to a 10m/s liquid
speed. The measure units are shown as appear on the display. The British and American units are
diversified by using capital and small characters.
When a mass measure unit is set, the specific gravity function is automatically enabled by the
system. Please, note that the mass measure is heavily affected by the temperature. With certain
liquids this may cause significant measurement errors. The following time measure units can be
selected: s = second, m = minute, h = hour, d = day.
(POS. 2.3) Measure unit and decimal places number [Tot.MU=dm³ X.XXX]
Setting the measure unit and decimals places number displayed for the volumes. To set the
measure unit, position the cursor on the measure unit field. To set the unit type, position the cursor
on the blank space between the measure unit and the numeric value; the decimal places number
can be selected by placing the cursor on numeric field and choosing one of the possible
combinations: 1000-01.00-001.0-00001.
(POS. 2.4-5) Pulse value channel 1-2 and total measure unit [Pls1-2=dm³ X.XXXXX]
Setting of a flow volume by which a corresponding pulse will be emitted on channel 1-2. To set the
parameter, complete the three fields, from left to right: 1) measure unit, 2) unit type and 3)
numeric value. The selection is performed by positioning the cursor in the field to be modified. To
change the unit type (metric, British or American, mass or volume) 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 meters (m) or feet
(ft). Only those units described above are available to be selected. This function is active only if the
pulse emission on channel is enabled.
(POS. 2.6-7) Pulse duration channel 1-2 [Tpls1-2=ms XXXX.XX]
Setting of the pulse duration generated on channel 1-2. This 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 be set to a minimum of 0.04 milliseconds. ATTENTION: since the converter can not
detect which device type is connected to the converter, the user must verify that the set pulse
duration is compatible with the external device processing such pulses. If, for example, an electro-
mechanical pulse counter is connected, one of two problems may occur; firstly, if the pulse is too
long the coils may burn out, secondly, if the pulse is too short, the counter may not be able to
function, with the possibility of causing damage to the output.
MENU 3 - MEASURE
(POS. 3.1) Main frequency filter [AC filter=s X.X]
This function allow to filter electrical noise on the liquid coming from the main frequency. The allowed
values are: 0.2s and 1.0s; 0.2s=ready measure and 1.0s=liquid noise filter.
