3.1 Overview

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:

Applications

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.

Integration

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.

Transmitter communication solutions

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.

3.5 Principle 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).

SONO 3500 CT flowmeters

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 × (t

B,A

A,B

) / (t

A,B

× t

B,A

) = K × Δt/t²

– t
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 (D

and Du) shown in the figure below.

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.

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.

CT

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 following shows how to set Pulse Output A and Qmax. For other parameters, refer to
"Parameter list" in the appendix.

Setting Pulse Output and Maximum Flow (Q

1. In SIMATIC PDM navigate to menu "Device" → "Pulse guide"
The "guide" calculates the pulse-frequency at the max flow condition and tells you how
close you are on over-speeding the pulse-output.
The volume per pulse is freely scalable from 0.000001 to 10000 units per pulse. It also
calculates the minimum volume per pulse you can choose to avoid pulse over-speeding.
The maximum output frequency depends on the pulse selected; e.g. maximum output
frequency at 5 ms is 100 Hz. Increasing the pulse width lowers the maximum output
frequency.

2. Select maximum flow rate (never to be exceeded).

3. Select an appropriate pulse width, e.g. 5 ms.

4. Enter a value in "Amount per pulse A", e.g. 100, to define the volume/pulse with respect
to the "Minimum amount per pulse value".

5. Press "Apply Change of Pulse" to apply the settings.

Diagnosing with PDM

Online process values are available under menu "View" → "Display".

The "Measured Track Values" tab shows the gain steps and the flow velocities for path 1 and
path 2. For 1-path applications the values for path 2 (track 2) are "0".

The gain steps depend on the pipe size and the conditions of the measuring media.

The flow velocities depend on the flow in the pipe.

The battery is not rechargeable; it should be replaced at least every 6 years.

Consumption and battery operation time calculation

Every 5 minutes the advanced power management system of the transmitter calculates the
battery consumption and the remaining battery operation time.

The ambient temperature of the transmitter its also influence the battery capacity.

The typical operation time up to 6 years is based on only 80% battery capacity, low pulse
output frequency, seldom use of communication and an operation time/temperature profile of
5% at 0 °C (32 °F), 80% at 15 °C (59 °F) and 15% at 50 °C (122 °F).

The effect of other temperatures is shown in the figure below.

A variation in temperature from 15 °C to 55 °C (59 °F to 131 °F) reduces the capacity by
17% (in the figure from 15 Ah to 12½ Ah).
