Chapter 1 Overview
The temperature and level transmitter is applied to fluid
depth measurement at industrial areas, transfers measured
depth value to standard signal such as (4~20)mA/ (0 ～5)V/
RS485. It matches various instruments, and is widely used in
transportation,oil,chemical, metallurgical, light industry and
other fields.

Chapter 5 Notes
Read wiring diagram carefully before installation.
Turn off the power and the valve of the tested
medium during installing and disassembling, the
pressure is reduced to atmosphere pressure to avoid
accidents caused by medium ejection.
Make sure the transmitter is firmly connected and
properly grounded during installing, avoid vibration
and strong EMI environment. Ensure the good
grounding in outdoor installation, and lightning
protection measures should be taken to prevent
lightning from damaging the products.
For the accuracy of measurement, the fluidity of the
medium should be ensured.
It prohibited to insert hard objects into the pressure
hole to prevent damaging the sensor diaphragm.
Prevent the cable damages so that fluid could not
enter transmitter cavity through the damages and
signal wire joint, which will damage the product.
Explosion-proof products should be used in the
working conditions requiring explosion protection.
Avoid serious personal injury and heavy property loss
caused by incorrect operation and selection.

Description:
If the device receives a function code other than 03H, 06H,
or 10H, the abnormal response code 01H will be returned.
In order to protect the important parameters of the device
from being damaged, some registers only support users’
reading operation (03H function code). If these registers
are written (06H, 10H function code), the abnormal
response code 02H will be returned.
The operation data section only supports writing
operations (06H, 10H function code). If these registers are
read (03H power code), the abnormal response code 02H
will be returned.
Read/write operations on addresses beyond the range of
the offset address allocation table will return the abnormal
response code 02H.
In order to prevent some registers from writing illegal
parameters, when the registers in the user data area are
written (06H, 10H function code), the device will verify the
