Notes: as the product is renewed continuously, it cannot be ensured that the product
manual and installation manual are in line with the latest product.
The Company cannot inform every client of the change (if any) in product itself and its
operation instructions. Please directly contact the corporate sales personnel for any
needs. The change includes but is not limited to the following:
Product blind area, performance parameters, functions, structure, shape, color, etc.
Software functions, structure, display mode, operating habit, etc. Any operation on the
hardware must be conducted after power off.
Failures, like short circuit, caused by power-on operation are beyond the range of warranty.
The uncapping operations must be conducted after power off and no liquid is allowed to
enter in the meter. Any failure caused by the entering in of liquid is beyond the range
of warranty.
Normally the ultrasonic level meter produced by the company shall be installed as per
the installation requirements of the manual and after that, the equipment can be normally
used only after the following several parameters are set.
There are three buttons on the panel, via which the meter can be adjusted. The measured
values are displayed on the LCD screen after the adjustment.

Minimum of measuring range: it is the value of distance between the reference
plane to the position, which is positive when the minimum of measuring range is
above the reference plane and negative when the minimum of measuring range is
below the reference plane. The output current is 4mA when the liquid level is at
such position.
Maximum of measuring range: it is the value of distance between the reference
plane to the position, which is positive when the maximum of measuring range is
above the reference plane and negative when the maximum of measuring range is
below the reference plane. The output current is 20mA when the liquid level is at
such position.
(4)Operating with relay: enter in the alarm settings and set three parameters:
①Alarm mode: select high level alarm, low level alarm or off.
②Alarm value: high level alarm: alarm given when the liquid level is above the alarm
value
Low value alarm: alarm given when the liquid level is below the alarm value
③Return difference value: it is used to prevent the repeated switching of alarm switch
near the alarm point caused by measurement error.
High level alarm state: alarm cancelled when the liquid level is less than (alarm value
- return difference value)
Low level alarm state: alarm cancelled when the liquid level is greater than (alarm
value + return difference value)
(5)Please set the options of probe selection, parameter correction and algorithm selection
under the instruction of professional technicians.
(6)The installed equipment must be grounded truthfully and independently and shall not
share the public grounding with electrical cabinet or meter box.
(7)Suggestions: when the ultrasonic level meter is connected with the frequency
converter, PLC and other equipment with interference, the power supply part
shall be added with isolation transformer, signal part shall be added with signal
isolator and reliable grounding shall be provided.
★The signal line shall not be wired in the same trunking with the power line and it shall
be installed independently through metal tube or far away from the power line. If the
signal line is not installed through tube independently, it shall be kept at least 1m away
from the power line.

I. Product Introduction
Ultrasonic level meter (for material and liquid level measurement) is a
non-contact highly reliable and cost-effective material level measuring
instrument which is easily installed and maintained. It can meet most of the
material level measurement requirements without touching the medium. It is
a new generation ultrasonic level meter with fully independent property
rights developed by the company via years of hard work.
II. Commissioning
As the meter installation site environment is different, the basic information
of measurement to be done must be learnt before the operation of the ultrasonic
level meter, such as the measuring range, zero point, full scale and site
conditions. Therefore, the meter must be set before measurement and the
specific settings are detailed in “Operating Instructions for Simple Settings
of Ultrasonic Level Meter Menus” in Page 1.
Others: please do not modify probe selection, parameter correction and
algorithm selection without permission.

Remarks: this series of ultrasonic probe can also be customized as per client's
demand and the customized probes are probes with special specification
requirements, such as resistance to high pressure, resistance to high
temperature, small diameter and small blind area.

4.2 Installation Guide
4.2.1 Understand terminology
①Measuring range: the meaning of measuring range is very important for
meter type selection. Please refer to the diagrams below.
②Emitting angle and false echo
Ultrasonic wave beam is gathered by the probe. The emitting of impulse
wave beam is like the light beam of flashlight. The further it is from the probe,
the greater the diffusion area is.
Any objects within the range of emitting angle, such as pipe, support,
weld joint, reinforcing rib, mixing propeller and hanging object, will lead to
strong false echo, specially the objects within the range of emitting angle
which are near the probe.
For example, the false echo caused by the pipe at 6m from the probe is 9
times stronger than that caused by the same pipe at 18m from the probe

Operation Manual
★Try every effort to make the sensor axis perpendicular to the medium
surface and avoid any other object within the range of emitting angle, such as
pipe and support.
4.2.2 Select measuring range
Measuring range is decided by the range of ultrasonic probe which is
subject to the site working environment, object to be measured and temperature,
etc. Decide the measuring range needed based on the table below.

Total minimum: 15dB, maximum: 40dB
Under such circumstances, if the actual maximum measuring range is 5m,

measurement.
4.2.3 Installation of thread at the bottom
▲It is recommended to use plastic flange to connect with the sensor
during the installation.
◆Installation of thread at the bottom
01.Install a flange on the object to be measured
02.Place a spacer of the same inner diameter on the flange
03.Align the transducer with flange hole

waveguide.
4.2.5 Liquid measurement
4.2.5.1 Flat-top tank
Normally, the flat-top tank has a short connecting pipe whose datum plane
is the undersurface of flange. Under the premise that the connecting pipe length
is≤60mm,innerdiameteris≥100mmandinnerwallissmoothandfreeofburr
and bulges, the measurement can be carried out if the emitting surface of
installed probe is 3cm below the flange undersurface.

The most ideal installation is to directly install the meter on the flat-top
container without using the connecting pipe and the round opening on the
container is good enough for the fixing of mounting flange or cardan joint. The
probe emitting surface is below the datum plane.
Flange-type (locking flange) installation on the flat-top tank
Flange-type installation on the flat-top tank without connecting pipe
In case of installation on nipple joint similar to a probe, the inner
diameter of connecting pipe shall be identical to the external thread and the
probe emitting surface must be exposed for at least 1cm from the connecting
pipe and it shall not be inside the connecting pipe.

×1.5.

4.2.5.2 Arch tank top
For arch tank, it’s better not to install the meter in the middle of the tank
top. Instead, the meter shall be installed at 1/2 or 2/3 of the tank top radius
(under the premise that certain distance from the tank wall is met). The arch
tank top is like convex lens to the ultrasonic pulse. If the probe is installed at

the focus of convex lens, it will receive all the false echoes. Therefore, the
sensor shall not be installed in the middle of the arch tank top.
Installation on nipple joint – arch tank top
Installation on flange – arch tank top
For most arch tanks, the length of connecting pipe plus flange on the top
is 150-180mm. But the part below the probe thread of ultrasonic level meter is
not so long (elongated probe is available for customization to make sure the
probe emitting surface is below the connecting pipe bottom). In this case, the
proportional relation between the diameter and length of connecting pipe shall
be noted.
