2 Application
The magnetic-inductive flow velocity sensor PIT-UMF2 (B) is used to measure or monitor the volume
flow of liquids with and without solids concentration and also other electrically conductive media while
minimizing pressure drops. The conductivity of the medium must be at least 20 µS/cm. Pressure,
temperature, density and viscosity do not affect the volume measurements. Smaller portions of solid
particles and small gas bubbles are also measured as part of the volume flow. A larger number of
solid particles or gas bubbles will lead to failures. Special electrodes are available for media that tend
to form greasy films or crusts.

3 Mode of Operation and System Design
3.1 Mode of operation
It was back in 1832 that Faraday suggested utilizing the principle of electromagnetic induction for
measuring flow velocities. His experiments in the Thames, though unsuccessful due to superimposed
polarization effects, are nonetheless regarded as the first ones in the field of magnetic-inductive flow
measurement.
According to Faraday’s law of electromagnetic induction, an electrical field E is produced in a
conductive liquid moving through a magnetic field B at a velocity v in accordance with the vector
product E = [v x B]. A liquid at flow velocity v and a flow rate Q flows through a meter tube (4),
producing a measuring-circuit voltage Um at the two electrodes (E1 and E2) at right angles to the
direction of flow and the magnetic field B generated by the field coils (3). The size of this measuring-
circuit voltage is proportional to the mean flow velocity and thus the volume flow rate.
3.2 System design
The magnetic-inductive PIT-UMF2 (B) flow measurement system consists of a sensor (PIT), which
picks up an induced measuring signal from the medium flowing through the pipe, and a transmitter
(UMF2 (B)), which transforms this signal in standardized output signals (4-20 mA or pulses).
The PIT-*** sensor can be operated with all transmitters for magnetic-inductive flow meters
manufactured by Heinrichs Messtechnik. The sensor is installed in the pipe while the transmitter is
mounted directly on the sensor or separately on the outside, depending on the equipment design.

3.2.2 Remote installation of the transmitter
Heinrichs Messtechnik recommends this type of installation when there is little space or the medium
temperatures are high. The sensor and the transmitter are connected by a field coil and an electrode
cable. The electrode cable must be shielded and protected against disturbing interferences.

5 Conditions of use
5.1 Installation conditions
Disturbing elements (e.g. shut-off and control valves) are to be arranged downstream from the sensor.
If this is not possible, flow conditioners must be installed so that no vortexes can reach the pipe
section of the sensor. The mounting location in the pipe system should be selected so that the sensor
is continually filled with the medium. This requirement can be met by using drains and check valves.
.
In order to stay within the indicated accuracy, the installation must be performed according to
EN 29104 "Measurement of Fluid Flow in Closed Conduits –Methods of Evaluating the Performance
of Magnetic-Inductive Flow meters." Based on this standard, the minimum straight run of pipe ahead
of the inlet must be 10 pipe diameters (> 10 x DN) and 5 pipe diameters following the outlet (> 5 x DN)
[DN = nominal diameter of pipe].
In order to prevent serious measuring errors when the pipe is partially filled or when there are gas
bubbles or sediment deposits, the mounting position described above should be chosen.
The limits for the product and ambient temperature must be met at the mounting location. Corrosive
atmospheres must be avoided. Please also take into account the space requirement for a possible
removal of the device.
5.1.1 Immersion depth of PIT-*** in the pipe
In order to suppress the influence of the flow profile as much as possible, the depth of immersion of
the sensor head in the pipe must be 15 % of the inside diameter of the pipe. The socket weld fitting
must not cover the top of the sensor head and must be shortened if necessary.

Operating Manual PIT-UMF2 (B) Heinrichs Messtechnik GmbH
Page 7 of 14
5.1.2 Removal and installation under process pressure
For easy removal and installation under pressure, a special retraction device is available. When using
this device, the sensor head must not be damaged by closing the valve.
For details, see the Additional Operating Instructions for Removal and Installation the meter under
process pressure Additional Operating Instructions PIT-Druck_BA_0X_eng.doc (see also Section 14
"Options").
5.1.3 Grounding
For safety reasons and to ensure faultless operation of the magnetic-inductive flow meter, earthing of
the flow sensor is important. In accordance with VDE 0100, Part 540, the earthing connections must
be connected to the grounding conductor. To avoid false measurement, the ground potential must be
identical to the ground potential of the medium.
When using insulated and lined pipes or plastic pipes, the metrological grounding of the medium for
PIT-S (SS) is carried out via the wetted part of the sensor head.
All wetted parts of PIT-A (PFA) are coated with PFA. Therefore it is not possible to ground the medium
via the housing parts. In this case make sure that the PIT-A sensor will be supplied an earthing. If the
sensor does not have an earthing electrode ensure that a suitable earthing disc will be used.
5.2 Use in hazardous areas
The flow meters PIT-…/UMF2 (B) are not intended for use in hazardous areas.
5.3 Ambient conditions
5.3.1 Ambient temperature ranges
-20°C to +60°C, below 0°C the readability of the LCD is limited
5.3.2 Storage temperature
-25°C to +60°C
5.3.3 Climatic category
In accordance with IEC 654-1
Not weather-protected Class D locations exposed directly to open-air climate
5.3.4 Ingress Protection
PIT standard sensor: IP65, option: IP68
UMF2 (B) standard housing IP68 (NEMA 6P)
Caution:
Ingress protection IP68 is only achieved if suitable and tightly screwed down cable
glands or conduits are used. If the cable glands are only tightened manually water may
leak into the terminal compartment in the housing.
Danger:
Particular care must be taken if the window in the housing becomes fogged over or
discolored because moisture, water or product might seep through the wire sheath into
the terminal compartment in the housing!
Warning:
Electromagnetic compatibility is only achieved if the electronics housing is closed.
Leaving the enclosure open can lead to electromagnetic disturbances.
5.3.5 Shock resistance/vibration resistance
The meter should be protected from extreme shocks and vibrations, which could cause damage.
