Portable Ultrasonic Water Depth Meter---HLU-SF
1. Profiles:
Holykell HLU-SF ultrasonic water depth meter is used in reservoirs, lakes, rivers or shallow sea water
etc. The main principal is to place ultrasonic transducer above water or in water and use ultrasonic spreading
in the water to get calculated water depth by instrument. This instrument adopts the international advanced
technology, equipped also with water depth measurement functions, control functions, data transfer functions
and man-machine communication capabilities. This instrument is a water depth measurement instrument of
ultrasonic receive and dispatch sensor, servo circuit, temperature compensation, salinity compensation and
compensation circuit unit, monitor, and control signal output and serial data or analog output unit (optional).
Its main advantages are high reliability, long life, easy access, simple operation, accurate measurement of
features and less-maintenance, it has already been widely used in the hydrographic survey, hydropower
plant, reservoir area, shallow seas, lakes, rivers, surveying, environmental waters monitoring etc.
■ the water depth meter has different compensation of water quality and water sound temperature for sea
water, river water, and cost performance are surpassed import type.
■Standard configuration of instrument: 1. Sensor; 2. handheld instrument, high-capacity lithium-ion battery
(built-in), 3.Dedicated charger. Can be selected a variety of portable protective box when you ordering.

6. Installation dimension of sensor：
【The following picture is the schematic diagram of sensor body, the final size and appearance is subject to
the real goods】
◆Installation suggestion: sensor installation should consider the protection requirements of the cable, we
suggest to make cable through the pipe, then connect pipe to sensor connector, other external fittings can
connect the pipe directly. In order to avoid cable fracture to cause permanent damage of sensor, cable
should be avoid under the stress of the installation of fittings.
7. Application Notice:
1. Ultrasonic water depth sensor is precision instrument, it must be power on more than 5 minutes before
using.
2. Ultrasonic water depth sensor can only work in the water. It can't work in the air.
3. It needs input N value( salinity value) in the P1 menu when it works in the sea water.
4. Ultrasonic water depth sensor has been matched with instrument circuit, can’t be interchangeable. In order
to improve the service life of instrument, please build awnings above the water depth sensor when it works
outdoor, don't put the ultrasonic water depth sensor in the environment of long-term sunny or raining.
5. Transmitting power can’t be set too large or too small, otherwise it won’t be able to work normally
6. Ultrasonic water depth sensor has blind zone, the data display is random within the blind zone.
7. The sensitivity is very high of instrument, so there can't have too strong noise and electromagnetic
interference nearby when use it. It will affect the stability of the instrument and even shorten the service life
of the instrument if flow momentum is big, temperature and humidity isn’t within the regulation range,
temperature change too fast and instrument surface is with moisture condensation etc.
8. Strictly prohibit putting LCD products into high or low temperature environment.

8. Communication protocol of Serial port:
【Standard Baud rate】
Half duplex asynchronous mode, Baud rate can be set freely from 600 to 19200 BPS.
MC version communication format (standard Baud rate).
1: Host machine: After sending address (1 ~ 64)of binary code then inquire receiving data.
2: Slave: to response by interrupt mode, each frame sending 21 byte.
Sending data Sequence of Slave:
First 5 bytes is water depth value (5 bytes ASC code, the unit is meter)
The sixth to twentieth bytes is production testing code (no business of the user); the twenty-first byte is
"accumulation sum" verify word!
★For example: some time the superior machine receive a frame level data which sent by HLU-SF as follows,
30 2E 35 30 31 31 31 33 2E 37 36 31 41 5C 2D 86 3F 00 4D B5 E6
- - - - - depth value = 0.501m(30 2 E 35 30 31);
- - - - - 6-20 bytes is production testing code;
- - - - - E6 is accumulating sum
To enable users to enjoy better quality and frontier science technology achievement, HLU-SF products will
continue to upgrade, -- -- -- -- - if there is a technical subject to change without prior notice)

3. Don't properly used in air
environment;
4. There are two or more than two sets
of water depth meter are working in
close, causing echo interference;
5. The water has too big electromagnetic
interference; 6. Gain parameters has
been modified artificially.
1. Adjust the sensor’s axis and make
it perpendicular to the water surface
2.Generally, under 20 m range,
power P is about 10, above 30 m
range, power P is about 10 ~ 15
(also have special);
3.Put the sensor into water to
measure;
4. Move another instrument to the
distant measurement area;
5.Shielding interference; 6.Contact

"----"
1.Depth of water meter’s range is small,
but the working range is too big;
2.The application range is not wrong, the
application of the water environment
turbidity is too large or bed no reflection
conditions, and can't get the echo;
3. Setting of Power P is too small or too
large.
1. Adjust the working range of water
depth meter to actual range;
2. Adjust application environment to
appropriate water with reflection
plane;
3.Access to user menu the depth of

transmitted power, increase or
decrease P until display is
stable.
The sensor has sound
and the error of water
depth value error is more
than ten centimeters...
1.There is a large obstacles in water
under sensor, which cause reflection
wave;
2.The installation is too nearby the
shore side, wave distinguishes is reflex
midway;
3.Check whether it is correct of "N
value" setting;
4.Check whether it is normal of
