1. Overview and Warnings
The measurement method of ultraD water meter is based on dual path, transit-time, ultrasonic technology.
The ultraD water meters combine measurement, calculation and display, and can be widely used for regional
water supply systems and cooling water systems, etc. Read these instructions carefully before beginning
installation and save them for future reference.
This product is a precise measuring instrument and has been thoroughly inspected and tested before
shipment. So the calibration, maintenance and replacement should be operated by professionals. For
more technical support, please contact us.
The lead seal of the meter should not be destroyed. Otherwise, we are not responsibility for warranty.
This product is suitable for measuring clean water or homogeneous liquid in full filled pipes, not suitable
for measuring underground muddy water.
To select the installation location, please pay attention to the following points:
1. Do not install the meter near the variable frequency pump, electric machinery or other electromagnetic
interference environment.
2. If the installing pipe is connected by contracted pipe, expanded pipe, bends or other flow disturbers,
please select other installation location or rectify the pipeline (If you need the meter without installation
requirement of straight pipe, please contact the factory).
3. The preferred installation location is horizontal pipe, followed by the vertical pipe with upward (or obliquely
upward) flow, avoiding the downward (or obliquely downward) flow to prevent the partially filled pipe.
4. Since air collects at the highest point of the pipe, installation of the water meter should be at the lowest
point to avoid measuring errors.
Before installing the meter, ensure that the circulation line has been cleaned to prevent any stones, sand
or other debris.
It is recommended to install valve in the pipeline before and after the meter for easy maintenance. After
the meter is installed and before opening the pipeline valves, be careful not to form a negative pressure
in the pipe of the meter installation location, in order to avoid damage to the meter.
After installation is complete, it is recommended to keep the lid closed to avoid direct sunlight exposure.
If you do not use cable communications, please keep the cable for later use.
When communicating, do not make any cables of this product near heat sources to avoid damage to the
cable insulation layer caused by the deformation of the cable, so as not to cause fire or electrical
accident.

4. Display Description
The cumulative flow, instantaneous flow and the status flag are displayed on the LCD screen. It can offset
the drawbacks of the past magnet rod operation which requires to switch the display screen to see all
parameters of the meter. Operators can check the meter status at any time without a magnet rod.
Digital display contents are as follows:
4.1 Digital Display (DN15-25)
LCD display: The switch between different screens is achieved by the light button. The light button can work normally
when the light intensity meet the requirement. When it's dark, a lamp can be used to illuminate the light button.

5. Modbus Communication Protocol
5.1 Modbus-RTU Protocol Introduction
Ultrasonic water meter supports Modbus-RTU protocol. Baud rate: 1200, 2400, 4800, 9600 optional.
Character type 8 data bits, no parity bit, 1 stop bit

Start Bit: under RTU mode, messages start to send by interval time of 4 characters.
Address Code: Within a network, the address code is unique, range: 1--247. Address 0 is used as a
broadcast address, not for stand-alone communications.
Function Code: the water meter only uses function code 03, namely: read register data.
Data Area: corresponds to the function code 03, there are a total of four bytes when the mainframe sends
commands:

2 bytes
(register address)
2 bytes
(number of register)
The first two bytes are the first address of the register to be read;
The last two bytes are the number of register to be read (up to 22).
1 byte
the number of bytes in data
area
N bytes
specific register data
When the machine responds, the first byte is the number of bytes in data area (not including itself);
The following bytes in data area are the value of the register to be read; the length is determined by the first byte.
CRC Code: two-byte error detection code. Low byte is in front of high byte.
Terminator: after the transfer of the last character, the pause time of 4 character marks the end of the
message.
