3.Installation guide
3.1 Bracket installation and flange dimensions
Note: the flange size will change based on different transducers and will be
forewarned.
3.2 Installation guide
3.2.1 Bracket installation: fixed L-type bracket on the top of level, then fixed the
level meter on the bracket with screws.
3.2.1 Flange installation: fixed the flange on plate or board, then fixed the level
meter on the flange.
3.3 Principles of installation
3.3.1 Meter mounting height should less than optional instrument range.
3.3.1 The distance of transducer emitting surface to the highest level (blind spot)
should more than optional instrument range.
3.3.2 Transducer emitting surface should be parallel to the liquid surface.
3.3.3 Transducer installation location should avoid being below the inlet and out
surface of volatility.
3.3.4 If the tank wall is not smooth, instrument should be left more than 0.5m to
the tank wall.
3.3.5 If the distance from transducer emitting surface to highest level is less than
the blind spot, you need to install an extension tube, and be vertical to the
surface, the wall should be maintained smooth.

4.4 Parameter setting
4.4.1 Calibration steps
1）Liquid crystal display the level value after instrument plug in,
shown as the right figure, the actual level is 3.320m, calibration method
described as following
2）Using the “inductive-pen” to click Mode key to enter the parameter
setting menu, first entry is
the P01(level)calibration menu.
3）Click the OK button, enter the level calibration input interface, input
actual value of 3.320m, as the right figure, click Mode button return to
level menu
4）Then click Mode button again to display as shown, click Mode button
to return to parameter setting menu, click OK button to exit.
5）The instrument displays the actual level, from then on, the meter
readings will accurately reflect the actual level value.
4.4.2 Parameter 4~20mA setting
1）In a normal operation, click Mode button to enter the parameter
setting menu, then click▼to choose P02(4～20mA) setting menu,
shown as right figure.
2） 20 mA setting
a）Click OK button to enter 20mA parameter setting, crystal
shown as right.
b）Click OK button to enter 20mA value input interface, input
the value as right figure, indicated 20mA output when the level is 5m,
then click Mode to exit.
3）4mA setting
In the 20mA parameter setting menu click▼to enter 4mA
parameter setting menu, click OK button enter setting interface, method
as above.
4.4.3 Relay parameter setting

3）Click ▼ can choose other relays, click OK button to enter relay 1 setting interface,
shown as right figure, the formula indicated relay 1
The relay pick-up when the level is greater than 4m and less than 8m. < and >
symbol location in the interface can choose “<” and “>” two symbols, & symbol
location can choose “&” 、 “|” 、 “N” 、 “∧” four symbols. Click OK button make the
necessary modified symbol flashing, click▲ or ▼ to choose necessary symbol,
modify as the former.
Symbol meaning:
＜：“less than” sign
＞：“greater than” sign
&： “and” sign, indicated both conditions should be met.
| ： “or” sign, indicated meet on of the two conditions is ok.
N ：only the first condition, does not display the second.
∧：the first one is relay pick-up condition (general used for starting the pump),
the second is relay open condition (general used for stopping the pump), mainly used
for the control of drainage and inflow wells.
4）If the relay setting as right figure, indicated the relay pick-
up
when level is less than 1m, if change the “＜” to “＞”, means relay pick-
up when level is greater than 1m.
If the relay setting as right figure, indicated the relay pick-up when
level is less than 1m or greater than 9m.
5）There is a more complex logic, such as drainage wells, start the
pump when the level raise to 8m, stop the pump when drain to 2m.
This logic is set as following:
>08.00∧<02.00 shown as right figure.
start the pump when the level raise to 8m, stop the pump when drain to 2m.
If it is inflow wells, start the pump when level down to 1m, stop the
pump when level raise to 6m. This logic is set as following:
<01.00∧>06.00 shown as right figure.
6）Then click Mode button to return to relay setting menu, click ▼ to
choose other relays: such as right figure, indicated relay 2. Click
OK to set, method as above.
4.4.4 Display mode
DispMode menu can set the display mode:
3.5.2.1 Level options display the level and relay state.
