The Power of Know How
Promag 23 P
Function and system design
Measuring principle
Faraday’s law of induction states that a voltage is induced in a conductor moving in a
magnetic field.
In electromagnetic measuring, the flowing medium corresponds to the moving
conductor. The induced voltage is proportional to the flow velocity and is detected by
two measuring electrodes and transmitted to the amplifier. Flow volume is computed
on the basis of the pipe’s diameter. The constant magnetic field is generated by a
switched direct current of alternating polarity.
I
Ue = B · L · v
Q=A·v
Ue = induced voltage
B = magnetic induction (magnetic field)
L = electrode gap
v = flow velocity
Q = volume flow
A = pipe cross-section
I = current strength

0.022[A]
RL[Ω] = Maximum load resistance, load (cable resistance)
US[V] = External supply voltage of 12 to 30 VDC (outgoing supply voltage,

UV[V] = Minimum supply voltage of 12 VDC, 13.9 VDC for intrinsically safe unit
(required supply voltage, transmitter)
IM[A] = Maximum signal transmission current (failsafe mode current output:
22 mA maximum current)
Caution!
The minimum load resistance (RL) necessary for a data transfer via HART® protocol
by way of the current signal cable is 250Ω. The minimum external supply voltage
(US) therefore, has to be 17.5 VDC (non-hazardous)

Potential equalization
Standard case
Sensor and medium must have the same electrical potential in order to ensure
measuring accuracy and avoid corrosion damage to the electrodes. Potential
equalization is achieved by means of the reference electrode installed in the sensor.
If the medium flows through unlined and grounded metallic pipes, it is enough to
connect the grounding terminal of the transmitter housing (see illustration below) to
the potential-equalization line. In the case of the remote version, this connection is
established by means of the ground terminal on the transmitter connection housing.
Caution:
For sensors without reference electrodes or without metal process connections, carry
out potential matching as per the instructions for special cases described below.
These special measures are particularly important when standard grounding
practice cannot be ensured or extremely strong matching currents are expected.
Metallic, ungrounded pipes
In order to avoid errors in measurement, use grounding cables to connect each
sensor flange to its corresponding pipe flange and ground the flanges. Connect the
transmitter or sensor connection housing, as applicable, to ground by means of the
grounding terminal provided for that purpose.
Note:
The grounding cable for flange-to-flange connections can be ordered separately as
an accessory from Endress+Hauser. The grounding cable is in direct contact with the
conductive flange coating and is secured by the flange screws.

Promag 23 P
Plastic pipes and lined pipes
Normally, potential is matched using the reference electrodes in the measuring tube.
However, in exceptional cases it is possible that, due to the grounding plan of a
system, large matching currents flow over the reference electrodes. This can lead to
destruction of the sensor, e.g. through electro-chemical decomposition of the
electrodes. In such cases, e.g. for fiber-glass or PVC piping, it is recommended to
use additional ground disks for potential matching.
When using ground disks, note the following points:
• Ground disks (1” to 8”) can be ordered separately from Endress+Hauser as an
accessory.
• Ground disks (including seals) increase the installation length. Refer to the
dimensions for ground disks on page 14.
Caution:
Risk of damage by electro-chemical corrosion. Note the electro-chemical series of
metals, if the grounding rings and measuring electrodes are made of different
materials.
9 AWG
Pipes with cathodic protection
If the medium cannot be grounded for process-related reasons, the measuring
device must be installed in such a way as to be potential-free:
• When installing the measuring device, make sure that there is an electrical
connection between the two piping runs, 9 AWG copper wire (6 mm2).
• Make sure that the installation materials do not establish a conductive connection
to the measuring device and that the installation materials withstand the
tightening torques applied when the threaded fasteners are tightened.
• Also comply with the regulations applicable to potential-free installation.

Installation conditions
Installation instructions
Mounting location
Correct measuring is possible only if the pipe is full. Avoid the following locations:
• Highest point in the run. Risk of air accumulating
• Directly upstream from an open pipe outlet in a down pipe
h³2xD
Installation of pumps
Do not install the sensor on the inlet side of a pump. This precaution is to avoid low
pressure and the consequent risk of damage to the lining of the measuring tube.
It might be necessary to install pulse dampers in systems incorporating reciprocating, diaphragm or peristaltic pumps. The sensor is shock and vibration resistant for
acceleration up to 2 g in accordance with IEC 68-2-6.
Partially filled pipes
Partially filled pipes with gradients necessitate a drain-type configuration. The Empty
Pipe Detection (EPD) function offers additional protection by detecting empty or
partially filled pipes.
Caution:
To avoid the risk of solids accumulating, do not install the sensor at the lowest point
in the drain. It is advisable to install a cleaning valve.

Promag 23 P
Down pipes
Install a siphon (b) or a vent valve (a) downstream of the sensor in down pipes
longer than 15 feet (5 meters). This precaution is to avoid low pressure and the
consequent risk of damage to the lining of the measuring tube. These measures also
prevent the system losing prime, which could cause air inclusions.

> 15 ft
a = vent valve, b = siphon
Orientation
An optimum orientation helps avoid gas and air accumulations and deposits in the
measuring tube. Promag, nevertheless, supplies a range of functions and accessories for correct measuring of problematic fluids:
Empty Pipe Detection (EPD) ensures the detection of partially filled measuring tubes,
e.g. in the case of degassing fluids or varying process pressures.
Vertical orientation:
This orientation is ideal for self-emptying piping systems and for use in conjunction
with Empty Pipe Detection.
Horizontal orientation:
The measuring electrode-plane should be horizontal. This prevents brief insulation
of the two electrodes by entrained air bubbles.
Caution:
Empty Pipe Detection functions correctly only when the measuring device is installed
horizontally and the transmitter housing is facing upward. Otherwise, there is no
guarantee that Empty Pipe Detection will respond if the measuring tube is only
partially filled or empty.

Vibrations
Secure the piping and the sensor if vibration is severe. The sensor is shock and
vibration resistant for acceleration up to 2 g in accordance with IEC 68-2-6.
> 30 ft
Inlet and outlet runs
If possible, install the sensor well clear of fittings such as valves, T-pieces, elbows,
etc. Compliance with the following requirements for the inlet and outlet runs is
necessary in order to ensure measuring accuracy:
• Inlet run ≥ 5 x pipe diameter
• Outlet run ≥ 2 x pipe diameter

Adapter pieces

With the help of the appropriate adapter pieces (reducers and expanders) the sensor
can be mounted in a pipeline of a larger diameter. For slowly flowing fluids, the
resulting higher velocity increases the measuring accuracy.
