Integral mount design
For devices with an integral mount design, the transmitter and
flowmeter sensor form a single mechanical unit.
Remote mount design
For devices with a remote mount design, the transmitter and
flowmeter sensor are mounted in separate locations.
The electrical connection between the transmitter and the
flowmeter sensor is provided by a signal cable.
A maximum signal cable length of 200 m (656 ft) is possible.
Notes on the ProcessMaster
The flowmeter sensor of the ProcessMaster is available in two
designs, which are distinguished by the design level (A / B).
Notes on the transmitter housing
The transmitter is available in two housing designs:
• Single-compartment housing:
In the single-compartment housing, the electronics
chamber and the connection chamber in the transmitter
are not separated from each other.
• Dual-compartment housing:
In the dual-compartment housing, the electronics
chamber and the connection chamber in the transmitter
are separated from each other.

Measuring principle
Measurements performed by the electromagnetic flowmeter are
based on Faraday’s law of induction. A voltage is generated in a
conductor when it moves through a magnetic field.

With the device-relevant application of this measuring principle,
a conductive measuring medium flows through a tube in which a
magnetic field is generated perpendicular to the flow direction
(see Figure 4).
The voltage induced in the measuring medium is tapped by two
diametrically opposed electrodes. This measurement voltage is
proportional to the magnetic induction, the electrode spacing
and the average medium velocity v.
Taking into account that the magnetic induction and the
electrode spacing are constant values results in a proportion
between the measurement voltage U
and the average medium
1
velocity.
From the calculation of the volume flow rate follows that the
measurement voltage is linear and proportional to the volume
flow rate
The induced voltage is converted by the transmitter to
standardized, analog and digital signals.

Gaskets
The following points must be observed when installing gaskets:
• To achieve the best results, make sure that the gaskets
and meter tube fit concentrically.
• To make sure that the flow profile is not distorted, the
gaskets may not intrude in the piping cross-section.
• The use of graphite with the flange or process connection
gaskets is prohibited. This is because, in some instances,
an electrically conductive coating may form on the inside
of the meter tube.
Devices with hard rubber or soft rubber liner
• Devices with a hard / soft rubber liner always require
additional gaskets
• ABB recommends using gaskets made from rubber or
rubber-like sealing materials

… Installation conditions
Grounding
The flowmeter sensor must be connected to ground potential.
For technical reasons, this potential must be identical to the
potential of the measuring medium.
In piping made of plastic or with insulating liner, grounding of
the measuring medium is done by installing grounding plates.
If stray potential is present in the piping, adding a grounding
plate on both ends of the flowmeter sensor is recommended.
Sensor insulation
1 Insulation
Figure 15: Insulation of the flowmeter sensor
In the high temperature design, the flowmeter sensor can be
completely thermally insulated. After the unit is installed, the
piping and sensor must be insulated in accordance with the
figure.
Inlet and outlet sections
1 Double manifold 2 Turn-off device
Figure 16: Inlet and outlet section, turn-off devices
The measuring principle is independent of the flow profile as
long as standing eddies do not extend into the measured value
formation, such as may for example occur after double
manifolds, in the event of tangential inflow, or where half-open
gate valves are located upstream of the sensor. In such cases,
measures must be put in place to normalize the flow profile.
A Do not install fittings, manifolds, valves, etc., right before the
flowmeter sensor.
B Inlet / outlet sections: length of the straight piping upstream
and downstream on the sensor.
Experience has shown that, in most installations, straight
inlet sections 3 × DN long and straight outlet sections 2 × DN
long are sufficient (DN = nominal diameter of the flowmeter
sensor).
For test stands, the reference conditions of 10 × DN straight
inlet and 5 × DN straight outlet must be provided, in
accordance with EN 29104 / ISO 9104.
Valves or other turn-off devices should be installed in the
outlet section.
Valve flaps must be installed so that the valve damper plate
does not extend into the flowmeter sensor.

General information on grounding
Observe the following items when grounding the device:
• For plastic piping or piping with insulating liner, the
ground is provided by the grounding plate or grounding
electrodes.
• When stray potentials are present, install a grounding
plate upstream and downstream of the sensor.
• For measurement-related reasons, the potential in the
station ground and in the piping should be identical.
Note
If the sensor is installed in plastic or earthenware pipelines, or in
pipelines with an insulating liner, compensating currents may
flow through the grounding electrode in special cases (e.g. with
corrosive measuring media, acids and bases)
In the long term, this may destroy the sensor, since the ground
electrode will in turn degrade electrochemically.
In these special cases, the connection to the ground must be
performed using grounding plates. Install a grounding plate
upstream and downstream of the device in this case.
