Function and system design. . . . . . . . . . . . . . . . . . . . . 3
Measuring principleA Prosonic Flow inline flowmeter measures the flow rate of the passing fluid by using sensor pairs located on
opposite sides of the meter body and at an angle so that one of the sensors in the pair is slightly downstream.
The flow signal is established by alternating an acoustic signal between the sensor pairs and measuring the time
of flight of each transmission. Then utilizing the fact that sound travels faster with the flow versus against the
flow, this differential time ( T) can be used to determine the fluids velocity between the sensors.
The volume flow rate is established by combining all the flow velocities determined by the sensor pairs with
the cross sectional area of the meter body and extensive knowledge about fluid flow dynamics. The design of
the sensors and their position ensures that only a short straight run of pipe upstream of the meter is required
after typical flow obstructions such as bends in one or two planes. Advance digital signal processing facilitates
constant validation of the flow measurement reducing susceptibility to multiphase flow conditions and
increases the reliability of the measurement.
Measuring systemThe measuring system consists of a transmitter and a sensor. Two versions are available:
• Compact version: transmitter and sensor form a mechanical unit
• Remote version: transmitter and sensor are mounted physically separate from one another

Operating conditions: Installation
Note the following points:
• No special measures such as supports are necessary. External forces are absorbed by the construction of the
instrument.
• The flowmeter flanges must be coplanar with connecting flanges and free from tension.
• The maximum permitted ambient temperatures ( ä 12) and fluid temperatures ( ä 13) must be
observed.
• Pay particular attention to the notes on orientation and piping insulation on the following pages.
• The correct operation of the measuring system is not influenced by pipe vibrations.
Installation instructionsMounting location
Entrained air or gas bubbles in the measuring tube can result in an increase in measuring errors or loss of
measurment.
Avoid the following mounting locations in the pipe:
• Highest point of a pipeline. Risk of air accumulating.
• Directly upstream from a free pipe outlet in a vertical pipeline.

Notwithstanding the above, the installation proposal below permits installation in an open vertical pipeline.
Pipe restrictions or the use of an orifice with a smaller cross section than the nominal diameter prevent the
sensor running empty while measurement is in progress.
a0006082
Installation in a down pipe (e.g. for batching applications)
Make sure that the direction of the arrow on the nameplate of the sensor matches the direction of flow
(direction of fluid flow through the pipe).
Orientations A, B and C recommended, orientation D only recommended under certain circumstances
Heating
Some fluids require heat to be transfered at the sensor. Heating can be electrical, such as electrical heat tracing
or by heat jacketing, the meter.
Caution!
"
• Risk of electronics overheating! Consequently, make sure that the adapter between the sensor and
transmitter and the connection housing of the remote version always remain free of insulating material. Note
that the orientation of the meter could significantly reduce the temperature at the electronics.
• If using an electric trace heating system whose heating is regulated via phase angle control or pulse packages,
influence on the measured values cannot be ruled out due to magnetic fields (i.e. for values that are greater
than the values approved by the EN standard (sine 30 A/m)). In such instances, it is necessary to
magnetically shield the sensor

Thermal insulation
Some fluids require suitable measures to avoid heat transfer at the sensor. A wide range of materials can be
used to provide the required thermal insulation.
a0005763-en
A maximum insulation thickness of 20 mm must be observed in the area of the electronics/neck..
If the device is installed horizontally (with transmitter head pointing upwards), an insulation thickness of min.
10 mm is recommended to reduce convection. The maximum insulation thickness of 20 mm must not be
exceeded.
Limiting flow
Information on limiting flow is provided under "Measuring range" in the technical data section.
Inlet and outlet runsIf possible, install the sensor well clear of fittings such as valves, T-pieces, elbows, etc. As a minimum, the inlet
and outlet runs shown below must be observed to achieve the specified accuracy of the device. The longest
inlet run shown must be observed if two or more flow disturbances are present.

Pressure Equipment DirectiveThe measuring devices can be ordered with or without PED (Pressure Equipment Directive). If a device with
PED is required, this must be ordered explicitly. For devices with nominal diameters less than or equal to DN
25 (1"), this is neither possible nor necessary.
• With the identification PED/G1/III on the sensor nameplate, Endress+Hauser confirms conformity with the
"Basic safety requirements" of Appendix I of the Pressure Equipment Directive 97/23/EC.
• Devices with this identification (with PED) are suitable for the following types of fluid:
- Fluids of Group 1 and 2 with a steam pressure of greater or less than 0.5 bar (7.3 psi)
- Unstable gases
• Devices without this identification (without PED) are designed and manufactured according to good
engineering practice. They correspond to the requirements of Art. 3, Section 3 of the Pressure Equipment
Directive 97/23/EC. Their application is illustrated in Diagrams 6 to 9 in Appendix II of the Pressure
Equipment Directive 97/23/EC.
