Function and system design
Measuring principle The measuring principle is based on the controlled generation of Coriolis forces. These forces are
always present when both translational and rotational movements are superimposed.
FC= 2 · m (v · )
FC= Coriolis force
m = moving mass
= rotational velocity
v = velocity of the moving mass in a rotating or oscillating system
The amplitude of the Coriolis force depends on the moving mass m, its velocity v in the system, and
thus on the mass flow. Instead of a constant angular velocity , the Promass sensor uses oscillation.
The measuring tubes through which the measured material flows are brought into oscillation. The
Coriolis forces produced at the measuring tubes cause a phase shift in the tube oscillations (see
illustration):
• At zero flow, in other words when the fluid is at a standstill, the two tubes oscillate in phase (1).
• Mass flow causes deceleration of the oscillation at the inlet of the tubes (2) and acceleration at the
outlet (3).
a0003383
The phase difference (A-B) increases with increasing mass flow. Electrodynamic sensors register the
tube oscillations at the inlet and outlet.
System balance is ensured by the antiphase oscillation of the two measuring tubes. The measuring
principle operates independently of temperature, pressure, viscosity, conductivity and flow profile.
Density measurement
The measuring tubes are continuously excited at their resonance frequency. A change in the mass and
thus the density of the oscillating system (comprising measuring tubes and fluid) results in a
corresponding, automatic adjustment in the oscillation frequency. Resonance frequency is thus a
function of fluid density. The micro-processor utilises this relationship to obtain a density signal.
Temperature measurement
The temperature of the measuring tubes is determined in order to calculate the compensation factor
due to temperature effects. This signal corresponds to the process temperature and is also available as
an output.
The temperature measurement cannot be used to generate data for invoicing in applications subject
to legal metrology controls.

tube to register a phase shift in the oscillation)
• Fluid density (proportional to resonance frequency of the measuring tube)
• Fluid temperature (measured with temperature sensors)
Measuring range in non-
custody transfer mode
Measuring ranges for liquids
Measuring ranges for gases
The full scale values depend on the density of the gas. Use the formula below to calculate the full scale
values:
max(G) = max(F) · (G) ÷ x [kg/m³]
max(G) = Max. full scale value for gas [kg/h]
max(F) = Max. full scale value for liquid [kg/h]
(G) = gas density in [kg/m³] under process conditions
Here, max(G) can never be greater than max(F)
Calculation example for gas:
• Sensor type: Promass F, DN 50
• Gas: air with a density of 60.3 kg/m³ (at 20 °C and 50 bar)
• Measuring range (liquids): 70000 kg/h
• x = 90 (for Promass F DN 50)
Max. possible full scale value:
max(G) = max(F) · (G) ÷ x [kg/m] = 70000 kg/h · 60.3 kg/m³ ÷ 90 kg/m³ = 46900 kg/h

Installation
Mounting location Entrained air or gas bubbles in the measuring tube can result in an increase in measuring errors
Avoid the following locations:
• Highest point of a pipeline. Risk of air accumulating.
• Directly upstream of a free pipe outlet in a vertical pipeline.
a0003605
Mounting location
The proposed configuration in the following diagram, however, permits installation in a vertical
pipeline. Pipe restrictors or the use of an orifice plate with a smaller cross-section than the nominal
diameter prevent the sensor from running empty during measurement.

Orientation Make sure that the direction of the arrow on the nameplate of the sensor matches the direction of flow
(direction in which the fluid flows through the pipe).
Vertical (Fig. V)
Recommended orientation with upward direction of flow (Fig. V). When fluid is not flowing, entrained
solids will sink down and gases will rise away from the measuring tube. The measuring tubes can be
completely drained and protected against solids build-up.
Horizontal (Fig. H1, H2)
The measuring tubes must be horizontal and beside each other. When installation is correct the
transmitter housing is above or below the pipe (Fig. H1, H2). Always avoid having the transmitter
housing in the same horizontal plane as the pipe.
In order to ensure that the maximum permissible ambient temperature for the transmitter is not
exceeded, we recommend the following orientations:
1= For fluids with low temperatures, we recommend the horizontal orientation with the transmitter
head pointing upwards (Fig. H1) or the vertical orientation (Fig. V).
2= For fluids with high-temperatures, >200 °C (>392 °F), we recommend the horizontal orientation
with the transmitter head pointing downwards (Fig. H2) or the vertical orientation (Fig. V).

"Caution!
The two measuring tubes are slightly curved. The position of the sensor, therefore, has to be matched
to the fluid properties when the sensor is installed horizontally .
a0004581
Installed horizontally
1 Not suitable for fluids with entrained solids. Risk of solids accumulating.
2 Not suitable for outgassing fluids. Risk of air accumulating.
Installation instructions Note the following points:
• No special measures such as supports are necessary. External forces are absorbed by the construction
of the instrument, for example the secondary containment.
• The high oscillation frequency of the measuring tubes ensures that the correct operation of the
measuring system is not influenced by pipe vibrations.
• No special precautions need to be taken for fittings which create turbulence (valves, elbows, T-
pieces, etc.), as long as no cavitation occurs.
• For mechanical reasons and in order to protect the pipe, it is advisable to support heavy sensors.
• Please refer to the verification ordinances for the installation conditions of the approval for custody
transfer in question.
The necessary steps for creating a measuring system and obtaining approval from the Standards
Authorities must be clarified with the authority for legal metrology controls responsible.
Inlet and outlet runs There are no installation requirements regarding inlet and outlet runs.

Zero point adjustment
All measuring devices are calibrated to state-of-the-art technology. Calibration takes place under
reference operating conditions 10. Consequently, the zero point adjustment is generally not
necessary.
Experience shows that the zero point adjustment is advisable only in special cases:
• To achieve highest measuring accuracy also with small flow rates
• Under extreme process or operating conditions (e.g. very high process temperatures or very high-
viscosity fluids).
