The S462 is an ultrasonic flow meter that is designed to measure the
flow and consumption of liquids within the permissible operating
conditions. S462 is using clamp-on technology that can be mounted
outside the pipe and brings flow measurement with benefits including
reduced installation costs, uninterrupted production, and no contact
with liquid to be measured.
The liquids that S462 can measure include the following:
•Cooling and heating water
•Drinking water
•Potable water
•De-ionized and de-mineralized water
•Sanitary liquid
•Purified water
•Other liquids on request
The default units are: Velocity in m/s, Volume flow in LPM and Total
Consumption in m3. Other units are available by configurations through
the optional display or the service kit.
The S462 flow meter is mainly used in industrial environment. It is not
developed to be used in e plosive areas. To use it in e plosive areas
please contact the manufacturer.

8 Installation and connection
Follow the instructions below to install the flow meter onto the pipe.
Step 1. Clean the pipe to make
sure no dirt, paint, or any stains
on its surface. Add the coupling
pads onto the sensor surface.
Step 2. Place the flow meter with
the upper brackets (installed
together e -works) on the pipe.
Install the meter on the side of the
pipe instead of the top to avoid
bubbles effecting the measurement.
Step 3. Place the two base
brackets directly under the upper
brackets across the pipe. Finally,
tighten the screws on both ends.
Step 4. Connect the cable to the
M12 connector and then tighten
them up.

After the flow meter is powered on, the self-diagnosis program starts to
run. The display will show the last selected main screen.
Signal Quality (SQ value)
Indicates the level of the signal detected using
the number from 0 … 99. 0 represents the
minimum signal detected and 99 represents the
ma imum signal. For a reliable measurement a
SQ value of >70 is required.
Adjust the transducer position repeatedly and
check the coupling pad frequently until the signal
quality detected is as strong as possible.

13 Menu operations
13.2 Setup menu
The Setup menu is used to do the configuration
of S462 after installation. These parameters are
important for proper operation of the
instrument.
Following options are available:
0. Pipe parameter
1. System setting
2. Calibration
3. Output setting
13.2.1 Setup Menu – Pipe parameter
Every installation requires pipe settings and fluid settings at least.
Following settings are done here:
•0: Outer diameter of pipe
•1: all thickness of pipe
•2: Material (PVC, Carbon steel, Steel, or
Copper)
•3: Fluid type (Water, Sea Water, oil,
others). For others the sonic velocity of the
fluid to be measured needs to be entered.
Note: The above four settings are crucial for an
accurate measurement.

13 Menu operations
13.2.2 Setup Menu – System setting
The system settings have following options:
0. System Unit：Metric or Imperial units
1. Flow rate unit：m3/h, LPM, or GPM
2. Total unit：m3, L, or GAL
3. Totalizer RESET：To clear the consumption
counters to zero
4. Time set: To set the time. Generally, it is
unnecessary to modify date and time because the
system comes with a highly reliable perpetual
calendar chip.
5. System lock: To lock or unlock S462. Once the
system is locked, any modifications to the system
are prohibited, but parameters are readable. You
can “unlock” the system by entering your password.
If you forget your password, contact the
manufacturer.
6. System INFO: To display system information
consisting of the Serial number (SN) of the
electronics system. This S/N differs from the S/N
printed outside the instrument on the label. Both
S/N can be used for tracking.
7. Display Direction: Depending on the
installation it may required to swap the display
direction.
8. Damping: A damping factor can be entered to
stabilize the reading. Default is 3.
S462 17
13 Menu operations
13.2.3 Setup Menu – Calibration
The system settings have following options:
0. Scale factor: Refers to the ratio between “actual
value” and “reading value”. For example, when the
actual value is 2.00, and the meter displays 1.98 on
the screen, the scale factor reading is 2/1.98. The
default scale factor is factory calibrated and close
1.000.
1. 4-20mA CAL: Can be used to calibrate / adjust
the 4-20 mA output. Pressing the <Enter> selects
between 4 mA and 20 mA output. By using an amp-
meter the accuracy can be checked. If the reading is
not accurate it can be adjusted with the <arrow>
keys.
2. Set zero: Is used to make a zero flow calibration
or to reset the last calibration and bring it back to
factory setting. In order to make a zero calibration
there must not be any flow in the pipe!
Use the <arrow> keys to select between the 2 choices
and press <Enter> to activate. The calibration process
may take a few seconds.
3. Low flow cut: When the flow rate falls below the
low flow cutoff value, the flow indication is set to zero.
This function can prevent the flow meter from reading
the flow rate after a pump is shut down but there is
still liquid movement in the pipe, which will result in
totalization error.
Generally, 0.03m/s is recommended to enter as the
low flow cutoff point. The low flow cutoff value has no
relation to the measurement results once the velocity
increases over the low flow cutoff value.
4. Manual zero: When the zero point cannot be set
due to on-site working conditions, a zero point can be
manually set to force the zero point to be achieved
(this function is not commonly used).

13.2.4 Setup Menu – Output
0. RS485 Setup:
0. Network addr: Is the device address within
the RS-485 network. Default is 001.
1. RS485 Baudrate: Available baudrates:
2400, 4800, 9600, 19200. Other parameters
are fi ed at 8 data bits, no parity, 1 stop bit.
1. 4-20 mA range: Is used to set the scaling of
the analog output to the desired flow rate in the
selected flow unit.
2. Alarm value: (not supported)
3. OCT output: (not supported)
4. OCT multiplier: (not supported)
13.2.5 Setup Menu – History data
0. By Day: lists the daily consumption of the past
63 days.
1. By Month: lists the daily consumption of the past
63 months.
2. By Year: lists the daily consumption of the past 9
years.
