Function and system design
Measuring principle Following Faraday's law of magnetic induction, a voltage is induced in a conductor moving through a
magnetic field.
In the electromagnetic measuring principle, the flowing medium is the moving conductor.
The voltage induced is proportional to the flow velocity and is supplied to the amplifier by means of
two measuring electrodes. The flow volume is calculated by means of the pipe cross-sectional area. The
DC magnetic field is created through a switched direct current of alternating polarity.

Measuring system The measuring system consists of a transmitter and a sensor.
Two versions are available:
• Compact version: Transmitter and sensor form a mechanical unit.
• Remote version: Sensor is mounted separate from the transmitter.
Transmitter:
• Promag 50 (user interface with push buttons for operation, two-line display, illuminated)
• Promag 53 ("Touch Control" without opening the housing, four-line display, unilluminated)
Sensor:
• Promag H (DN 2 to 150 / ¹⁄ to 6")

Potential equalization Perfect measurement is only ensured when the medium and the sensor have the same electrical
potential.
Metal process connections
Potential matching usually takes place via the metallic process connections in contact with medium
which are directly mounted on the measuring transmitter. This usually means that additional potential
matching measures are unnecessary.
Plastic process connections (DN 2 to 25)
If the process connections are made of a synthetic material, additional ground rings or process
connections with an integrated ground electrode must be used to ensure the potential between the
sensor and fluid is matched. No potential matching can affect the accuracy of the measurements or
cause the destruction of the sensor through the electrochemical decomposition of the electrodes.
When using ground rings, note the following points:
• Depending on the option ordered, plastic disks may be installed at the process connections instead
of ground rings. These plastic disks serve only as spacers and have no potential matching function.
In addition, they provide a sealing function at the sensor/process connection interface. For this
reason, with process connections without metal ground rings, these plastic disks/seals must not be
removed, or must always be installed.
• Ground rings can be ordered separately from Endress+Hauser as accessories.
When placing the order, make certain that the ground rings are compatible with the material used
for the electrodes. Otherwise, there is a risk that the electrodes may be destroyed by electrochemical
corrosion! You can find material data on 59.
• Ground rings, including the seals, are mounted within the process connections. Therefore, the fitting
length is not affected. You can find the dimensions of ground rings on 46.

Installation
Mounting location Entrained air or gas bubble formation in the measuring tube can result in an increase in measuring
errors.
Avoid the following installation locations in the pipe:
• Highest point of a pipeline. Risk of air entrainment.
• Directly upstream from a free pipe outlet in a vertical pipeline.
A0011899
Mounting location
Installation of pumps
Sensors may not be installed on the pump suction side. This precaution is to avoid low pressure and the
consequent risk of damage to the lining of the measuring tube. Information on the pressure tightness
of the measuring tube lining 28, "Pressure tightness" section.
It might be necessary to install pulse dampers in systems incorporating reciprocating, diaphragm or
peristaltic pumps. Information on the shock and vibration resistance of the measuring system 20,
"Shock and vibration resistance" section.

Partially filled pipes
Partially filled pipes with gradients necessitate a drain-type configuration.
The empty pipe detection function (EPD) provides additional security in detecting empty or partially
filled pipes.
!Note!
Risk of solids accumulating. Do not install the sensor at the lowest point in the drain. It is advisable to
install a cleaning valve.
A0011901
Installation with partially filled pipes
Down pipes
Install a siphon or a vent valve downstream of the sensor in down pipes h 5 m (16.4 ft). This
precaution is to avoid low pressure and the consequent risk of damage to the lining of the measuring
tube. This measure also prevents the liquid current stopping in the pipe which could cause air locks.

Orientation An optimum orientation position helps avoid gas and air accumulations and deposits in the measuring
tube. The measuring device also offers the additional empty pipe detection function (EPD) for the
detection of partially filled measuring tubes, e.g. in the case of degassing fluids or varying process
pressures.
Vertical orientation
This is the ideal orientation for self-emptying piping systems and for use in conjunction with empty
pipe detection.
A0011903
Vertical orientation
Horizontal orientation
The measuring electrode plane should be horizontal. This prevents brief insulation of the two
measuring electrodes by entrained air bubbles.
!Note!
Empty pipe detection only works correctly with horizontal orientation if the transmitter housing is
facing upwards. Otherwise there is no guarantee that empty pipe detection will respond if the
measuring tube is only partially filled or empty.

Inlet and outlet run If possible, install the sensor well clear of assemblies such as valves, T-pieces, elbows etc.

Inlet and outlet run
Adapters Suitable adapters to DIN EN 545 (double-flange reducers) can be used to install the sensor in larger-
diameter pipes. The resultant increase in the rate of flow improves measuring accuracy with very slow-
moving fluids. The nomogram shown here can be used to calculate the pressure loss caused by cross-
section reduction.
!Note!
• The nomogram only applies to liquids of viscosity similar to that of water.
• For high viscosities of the fluid the selection of a pipe with larger diameter may be considered to
reduce the pressure loss.
1. Calculate the ratio of the diameters d/D.
2. From the nomogram read off the pressure loss as a function of flow velocity (downstream from
the reduction) and the d/D ratio.

Length of connecting cable When mounting the remote version, please note the following to achieve correct measuring results:
• Fix the cable run or route it in an armored conduit. Cable movements can falsify the measuring signal
especially in the case of low fluid conductivities.
• Route the cable well clear of electrical machines and switching elements.
• If necessary, ensure potential equalization between sensor and transmitter.
• The permissible cable length Lmax depends on the fluid conductivity. A minimum conductivity of
20 S/cm is required for measuring demineralized water.
• When the empty pipe detection function is switched on (EPD), the maximum connecting cable
length is 10 m (33 ft).

At ambient temperatures below –20 °C (–4 °F) the readability of the display may be impaired.

!Note!
The permitted temperature range of the measuring tube lining may not be undershot or overshot (
20, Section "Medium temperature range").
Please note the following points:
• Install the device at a shady location. Avoid direct sunlight, particularly in warm climatic regions.
• The transmitter must be mounted separate from the sensor if both the ambient and fluid
temperatures are high.
Storage temperature The storage temperature corresponds to the operating temperature range of the measuring
transmitter and the appropriate measuring sensors.
!Note!
• The measuring device must be protected against direct sunlight during storage in order to avoid
unacceptably high surface temperatures.
• A storage location must be selected where moisture does not collect in the measuring device. This
will help prevent fungus and bacteria infestation which can damage the liner.
• If protecting caps or protective covers are mounted, these must not be removed before mounting the
device.
