3 Applications
3 Applications
The SUTO ultrasonic clamp-on flow meter S461 has all it takes to
measure reliable, easy and accurate flow and consumption of liquids.
Based on the transit time technology this flow meter comes with unique
features and outstanding performance.
The sensors are simply clamped onto the outside of the pipe and never
come in contact with the fluid. The main unit can be installed onto the
pipe, at the wall or onto a DIN rail.
The configuration and setup is made through the wireless smartphone
app S4C-US, which can be downloaded for free from the SUTO website,
Google Play Store and the Apple App Store.
The app allows the user to set up the device as well as reading live
values, logger configuration and logger data read out.
By adding 2 clamp-on temperature sensors the Energy Meter Version
monitors the efficiency of heat e changers.
The S461 comes also as portable version in a transport case.
The liquids that S461 can measure include the following:
•Acetone
•Alcohol
•Benzol
•N-Butane
•Butanol
•Kerosene
•Oil, Castor
•Oil, Diesel
•Oil, Fuel
•Water, distilled
•Water, Sea
•Others (please enter sonic speed)
The S461 flow meter is mainly used in an industrial environment. It is
not developed to be used in e plosive areas.

Determination of installation point
6 Determination of installation point
To maintain the accuracy stated in the technical data, the ultrasonic
transducers must be clamped on a straight pipe with unhindered flow
characteristics. The pipe can be in vertical or horizontal position.
Unhindered flow characteristics are achieved if the section in front of the
transducer (upstream) and behind the transducer (downstream) are
sufficiently long, absolutely straight and free of obstructions such as
edges, seams, curves, and so on.
The following table shows e amples of optimum installation locations.

14 S461

Determination of installation point
Principles to select an optimum location:
•Install the transducers on a long straight pipe. The longer the
better and make sure that the pipe is completely full of liquid.
•It’s recommended to place the transducers not on top of the pipe,
but rather at a side position to avoid air bubbles that may occur on
top of the pipe can effect the measurement.
•Make sure that the temperature on the location does not e ceed
the permitted temperature range for the transducers. Generally,
the closer to the room temperature the better.
•Take the pipe fouling into consideration. Select a straight and
relatively new pipe. If the condition is not satisfying, consider the
fouling thickness as part of the liner for a more accurate result.
Remarks:
Some pipes have a kind of plastic liner. Between the outer pipe and the
liner there may be a certain thickness difference that will prevent the
ultrasonic waves from direct traveling. Such conditions will make the
measurement impossible. Try to avoid this kind of pipes whenever
possible.
ATTENTION!
rong measurement may occur if the transducers
are not installed correctly.
•The flow meter is for indoor use only! At an outdoor installation,
the device must be protected from solar radiation and rain.
•It is strongly recommended not to install S461 permanently in wet
environment.

Connector arrangement
Note: When the S461 is used as a
flow meter, there are no T in and
T out connectors.
T in: Connect to the inlet temperature
sensor.
T out: Connect to the outlet
temperature sensor.
Down: Connect to the downstream
transducer.
Up: Connect to the upstream
transducer.
Vb/Modbus: Connect to the Modbus/
RTU output/power supply.
Option: Connect to the Modbus/TCP
output when it is a X-coded connector;
connect to analog/pulse output when
it is a A-coded connector.
3. The S461 comes with an optional Earth connection, which is
recommended to be used if the unit is operated in an environment
with high electrical interference. The terminal in the connector
arrangement diagram is used for Earth connection.
7.2 Electrical connection
The S461 comes with four M12 connectors, two M8 connectors (for Flow
and Energy meter).
