DISPLAY
3.3 LCD NEW
Calculating the display information significantly affects the power
consumption. When the application does not require a fast display refresh
rate, it is strongly advised to select a slow refresh rate. Information will not
be lost, every pulse will be counted, and the output signals will be
generated in the normal way. The following can be selected:
fast, 1 sec, 3 secs, 15 secs, 30 secs, off
When “off” is selected, the display switches off automatically. When an
update rate other than “fast” is selected, pressing a key will switch the
update rate to “fast” for 30 seconds. After this time, the display will return to
the configured update rate (or switch off).
Save battery lifetime by choosing an update time of 1 second or longer.
After the operator has pressed a button, the display refresh rate will always
switch to fast for 30 seconds. When 'OFF' is selected, the display will:
temporarily turn on after one of the keys is touched; and automatically turn
off after 30 seconds.
3.4 BACKLIGHT
(BRIGHTNESS)
The unit has a backlight. The backlight brightness can be adjusted from off
(0%) to max (100%) in steps of 20%.
●
The brightness cannot be adjusted for battery powered units.
●
When the unit is only loop powered, it cannot use the backlight. An
external supply is required instead.
3.5 BARGRAPH
The unit has a speedometer/bar graph around the edge of the display that
gives a quick impression of the actual flowrate. The following can be
selected:
●
Enable
: the bar graph is switched on.
●
Disable
: the bar graph is switched off.
3.6 RATESPAN
Sets the range of the speedometer. The display shows 0 – 100 and has 20
blocks. Therefore, each block represents 5% of the total range.
The number of decimals displayed depends on

MENU 4: FLOWMETER
To simplify the configuration of the Flowmeter, Total and Flowrate settings, the E110-P has an
automatic unit conversion feature. To use this feature, you only have to enter the average K-factor
and the related measurement unit.
Advantages/features
:
● The same K‑factor calculation is used for Total and Flowrate.
● All configuration is done in the Flowmeter menu.
The measurement units can be set for volume or mass units. Refer to the test/calibration certificate
provided with your flowmeter. The automatic unit conversion feature can be set to ‘Hand’, allowing
for independent configuration of total and flowrate, for example, when:
● measurement units are not supported, i.e. ‘revolutions’, or
● volume and mass units are used simultaneously.
Use the following procedure to set up the automatic unit conversion:
1.
4.1: FLOWMETER > SIGNAL
: Select the correct type of flowmeter signal.
2.
4.2: FLOWMETER > UNITS
:
Select the type of measurement unit (volume or mass) shown on the
certificate.
3.
4.3: FLOWMETER > UNIT
:
Select the measuring unit shown on the certificate.
4.
4.4: FLOWMETER > K-FACTOR
:
Enter the (average) K-factor shown on the certificate.
5.
1.1: TOTAL > UNIT
:
Select the desired measuring units for (accumulated) Total.
6.
2.1: FLOWRATE > UNIT
:
Select the desired measuring units for Flowrate.
For a detailed description and tutorials on the automatic unit conversion feature, refer to our website
(or ask your supplier).
Example
: How to manually calculate the K-factor for total or flowrate:
● The Flowmeter generates 65.231 pulses per US gallon.
● The required measurement unit is cubic feet (ft

).
