For safety reasons, it is expressly prohibited to modify or change the product without authorization.
Repair or replacement is only allowed to use the accessories specified by the manufacturer.
1.1 The explosion may cause death or serious injury.
When installing the device in an explosive environment, be sure to comply with applicable local,
national and international standards, codes and regulations. Ensure that the equipment is installed
in accordance with intrinsically safe or non-flammable site operating procedures.
1.2 Process leakage may cause serious injury or death.
If the process seal is damaged, the medium may leak at the connection.
1.3 Failure to follow the safety installation guidelines may result in death or serious injury.

1. Meter head assembly, converter circuit and LCD screen
2. Housing, protect the sensor circuit
3. Reed switch-resistance component, sensor circuit
2.2 Working Principle
The magnetic float in the measuring tube moves up and down with the fluid level or interface level
of the medium, so that the resistance value in the sensor circuit changes linearly, and then the
resistance value change is converted into a 4-20mA standard DC signal through the converter
circuit in the meter head assembly. LCD display or output to the control room through the output
terminal to achieve long-distance transmission of liquid level.
2.3 Packaging
Please take the packaging waste to a special recycling facility。

7. Configuration
7.1 Transmitter Configuration
This section mainly introduces how to use the 3 local keys (Enter key←┘), (up key "↑"), (down key
"↓"), combined with LCD display to configure internal parameters.
7.1.1 LCD display function overview
See (Figure 7-1) for full screen information. The variables that can be displayed on the LCD screen
include current (Figure 7-2), percentage (Figure 7-3) and main variable (Figure 7-4). You can set to
display a single variable, or you can set the percentage and the main variable to cycle display, and
the effective digits of the decimal part can be set (0, 1, 2, 3, 4 decimal places). The display mode is
set by 475 configuration software or button. If the percentage and main variable are set to be
displayed cyclically, the LCD will display these two variables alternately with a period of 3 seconds.
