FUNCTIONS DESCRIPTION
(functions description with access code< 3)
The following pages give a description of the most important functions and how they can be changed or
enabled/disabled by the user.
MENU 1 - SENSOR
(POS. 1.11) Electrodes cleaning [El. cleaning]
Selectable options: OFF, minimum, average and maximum. It is not recommended the use of this
function (let OFF) when the liquid has a conductivity less than 100μS/cm.
(POS. 1.12) Empty pipe threshold
[E.P. thr.=XXX]
This value represents the threshold of measure block to zero in empty pipe condition; the span
function is 0-255. Since the sensibility of empty pipe detection could be changed by the liquid
conductivity, ground connections, type of lining, in case of needed it is possible to adjust manually
the preset threshold. It is recommended to check periodically its proper functioning. Value
increasing means sensibility decreasing.
(POS. 1.13) Autozero calibration
[Autozero cal.]
This function activates the zero calibration automatic system. To perform this operation, it is
necessary for the sensor to be full of liquid, and the liquid be perfectly still. Even minimal
movement of the liquid may affect the result, and consequently, the accuracy of the system. Once
you are sure the above conditions have been fulfilled (and the percentage flow rate value is stable)
press the key and automatically activates the zeroing procedure, after which it is necessary to
check that the percentage value showed goes to zero, repeat the operation otherwise. When the
value is stable at zero, then press the key.
MENU 2 - SCALES
(POS. 2.1-2) Full scale N.1-2 [Fs1-2=dm³/s X.XXXX]
The Full scale range N.1-2 is the corresponding output signal (20mA) to the meters maximum flow
rate (max 10m/s). There are four fields to fill in order to set this parameter, from left to right: 1)
volume measure unit, 2) unit type, 3) time measure unit and 4) numeric value. The selection is
made by positioning the cursor on the field to modify. To change the measure unit type (metric,
British or American, mass or volume) the cursor has to be positioned on the symbol “/” (field N. 2).
When the nominal diameter is set to zero it is possible to modify only the numeric field, since the
measure unit stays at m/sec.
The following tables show the available measure units and the conversion factor by comparison
with 1dm
3 and 1kg. The transmitter accepts any kind of measure units combination satisfying both
the following conditions:
