Legal information
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to property damage.
The product/system described in this documentation may be operated only by personnel qualified for the specific task in accordance with the relevant documentation, in particular its warning notices and safety instructions.

|
The SONO 3500 CT ultrasonic flowmeter systems consist of a sensor and a transmitter. The transmitter is type-approved with the custody transfer (CT) approval for use in energy metering systems. The transmitter is designed to measure flow water applications.
The ultrasonic flowmeter transmitter comes as a mains-powered version with battery backup. The following table shows the ultrasonic flowmeter systems with these transmitter types:

Transmitter |
Flowmeter system |
SONO 3500 CT (2-path) |
incl |
SONO 3500 CT |
DN 100 to DN 1200 |
|
|
The flowmeter system includes:
●Mains-powered transmitter with battery backup
●The sensor is a 2-path sensor with flanges and inline transducers wet-calibrated from factory together with the transmitter (DN 100 (4") to DN 1200 (48"))
The transmitter is designed with fiberglass reinforced polyamide enclosure for remote or compact installation in normal areas. The remote versions are available with up to 30 meter distance from flowmeter to transmitter. When ordered as a compact version in the series SONO 3500 CT the transducer cables are pre-mounted at the sensor.
SONO 3500 CT transmitter |
SONO 3500 CT display |
The transmitter is available in an IP67/NEMA 4X/6 enclosure.
For spare part cases the transmitter is always ordered as part of a complete flowmeter system.
The transmitter can be ordered preprogrammed with the given sensor data (system serial number).

Operating Instructions, 11/2020, AQ237286479555en-010402 |
The following features are available:
●Mains-powered transmitter
●Battery backup with 3.6 V Lithium single D-cell battery
●Suitable for sensor pipe diameters from DN 100 (4") up to DN 1200 (48")
●IP67 (NEMA 4X/6) rated polyamide transmitter enclosure
●Factory preset to the nominal dimensions of pipe type and pipe size
●Programming via SIMATIC PDM
●Local control panel with single push button, 8-digit display and IrDA optical interface for communication with SIMATIC PDM
●Display showing accumulated volume as well as instantaneous flow rate. The displayed units are m3/h and m3
●Two digital outputs for volume pulse or alarm
●4-20mA output (optional)
The main application for the type-approved SONO 3500 CT flowmeters is measurement of water flow in district heating plants, local networks, boiler stations, substations, chiller plants, irrigations plants, and other general water applications.
The flowmeter pulse output is often used as input for an energy meter or as input for digital systems for remote reading. The transmitter has two pulse outputs, with functions that can be individually selected, and integrated IRDA (optical eye) communication interface (Modbus RTU).
The settings of the transmitter, for example flow and pulse output rate, are defined when ordering the complete flowmeter. If the flowmeter forms part of an energy meter system for custody transfer, no further approvals are needed, except possible local approvals.
The transmitter supports Modbus RTU communication via the optical IrDA interface at the display, enabling the change of different transmitter settings using the SIMATIC PDM software tool.
The transmitter is configured in a combination of hardware (HW) and firmware (FW). For the communication and parametrization via SIMATIC PDM a firmware-specific device description (EDD) is needed.

3.5Principle of operation
Physical principle
Figure 3-1 Velocity distribution along sound path
A sound wave travelling in the same direction as the liquid flow arrives at point B from point A in a shorter time than the sound wave travelling against the flow direction (from point B to A).
The difference in sound transit time indicates the flow velocity in the pipe.
Since delay time is measured at short intervals both in and against flow direction, temperature has no influence on measurement accuracy.
In SONO 3500 CT flowmeters the ultrasonic transducers are placed at an angle θ in relation to the pipe axis. The transducers function as transmitters and receivers of the ultrasonic signals. Measurement is performed by determining the time the ultrasonic signal takes to travel with and against the flow. The principle can be expressed as follows:
v = K × (tB,A – tA,B) / (tA,B × tB,A) = K × Δt/t² where
v = Average flow velocity t = Transit time
K = Proportional flow factor
This measuring principle offers the advantage that it is independent of variations in the actual sound velocity of the liquid, i.e. independent of the temperature.
The mechanical/geometrical pipe data is transducer angle (θ), distance between sensors (L) and pipe dimension (Di and Du) shown in the figure below.

Operating Instructions, 11/2020, AQ237286479555en-010402 |
Figure 3-2 Measuring principle
The ultrasonic signal is sent directly between the transducers. The advantage gained sending signals from point to point is an extremely good signal strength.

Installing/Mounting |
4 |
The flowmeter installation is done in two steps:
2.Transmitter installation
SONO 3500 CT flowmeters are suitable for indoor and outdoor installations.
●Make sure that temperature and ambient specifications indicated on the device type plate/label are not exceeded.
CAUTION
Direct sunlight
Device damage.
The device can overheat or materials become brittle due to UV exposure.
Protect the device from direct sunlight.
Make sure that the maximum permissible ambient temperature is not exceeded.
Refer to the information in Technical data (Page 68).
Ambient temperature for transmitter:
●-10 °C to +55 °C (14 to 131 °F)
●Non-MID versions -10 to +60°C (14 to 140°F)
●The enclosure rating of the transmitter is IP67 (NEMA 4X/6) or better.
4.2Sensor installation
4.2.1 |
Inlet/Outlet conditions |
|
|
Requirement for straight inlet before flowmeter |
|
|
In order to maximize performance it is necessary to have straight inlet and outlet flow |
|
|
conditions before and after the flowmeter. |
|
|
Furthermore, a minimum distance between flowmeter and pumps and valves must be |
|
|
respected. |
|
|
It is also important to centre the flowmeter in relation to flanges and gaskets. |

Operating Instructions, 11/2020, AQ237286479555en-010402 |
Make sure that flowmeter is positioned as low as possible to prevent air from being trapped in flowmeter at transducers.
Find a position on the pipeline where inlet pipe to flowmeter has a straight length as specified below.

The flowmeter can be installed between two reducers as shown. At 8° reducing angles the below pressure drop curve applies.
A water flow velocity of 3 m/s (V) in a sensor with a diameter reduction from DN 200 to DN 100 (D1/D2 = 0.5) gives a pressure drop of 9 mbar.
L2: Min. 10 x pipe diameter
Both versions can be insulated.
We always recommend insulation of sensor in the compact or remote version. For compact versions the insulation can prevent heat transfer to transmitter.
The transmitter is packed separately - ready for plug-in into base part.
There are two mounting versions of the transmitter (as shown in figures below):
●remote transmitter
●compact transmitter
Remote transmitter Compact transmitter
