2.2 Classification Zones
2.2 Classification Zones
Classification zones are described for areas where combustible gases, vapours or mist constitute an explosive hazard. When determining the explosion hazard, i.e. when categorising explosive areas, the "directives for avoiding the risks of explosive atmospheres with examples (ExRL)”
have to be taken into account. In special cases or in case of doubt the determination is done by
the supervising authorities.

2.2.1 Equipment group II, category 1 (Zones 0 and 20)
2.2.1 Equipment group II, category 1 (Zones 0 and 20)
Equipment of this category is for use in areas where an explosive atmosphere consisting of gas,
vapour, mist (zone 1) or of inflammable dust/air mixtures (zone 20) is present continuously or for
long periods. Normally this applies only to the inside of containers or apparatus (vaporizers, pipe
systems etc.). In these zones only electrical apparatus must be used carrying an EC type test
certificate issued by an acknowledged authority and only those which have been explicitly
approved for these zones.

The resistance of this stainless steel should however be verified by the user, particularly when
it is used in medium mixtures that may from time to time be exchanged with cleansing agents.
Its chemical resistance also depends on temperature, flow rate and concentration of the medium.

chemical resistance also depends on temperature, flow rate and concentration of the medium.
Stainless steel owe their resistance to rust mainly to their alloy combination with chromium, the
formation of chromic oxide on the steel surface resulting in a passive state. Contamination,
deposits on the surface, or foreign rust may however neutralize the passivity. Therefore care
should be taken to keep the surfaces clean.

2.3.3 Titanium G7, 3.7235
2.3.3 Titanium G7, 3.7235
Titanium is characterised by non-magnetizability and excellent corrosion resistance, particularly
against oxidising media. The resistance is due to the fact that the surface of titanium immediately
builds up an oxidation layer in presence of oxidation means protecting the material beneath
against corrosion.

The technological characteristics of low-alloy titanium G7 are equal to those of plain titanium of
the same strength category. Adding approximately 0.2 % palladium does not influence the
mechanical properties, but also adds considerably to the corrosion resistance of plain titanium.
So titanium G7 has proved to be extremely suitable for use in hydrochlorid or sulphuric acid
solutions with little concentration as well as – with due care – in oxalic acid.

3.1 Measuring procedure
3.1 Measuring procedure
The calorimetric measuring procedure is based on the physics of heat dissipation, i.e. a body with
a temperature higher than its surroundings supplies a medium flowing past that body with energy
in the form of heat. The amount of energy supplied is a function of temperature difference
and
mass flow.
The calorimetric measuring procedure is based on the physics of heat dissipation, i.e. a body with

The temperature difference
between the two sensors is kept constant and the mass flow is
determined by measuring the calorific power.
Fig. 12 is a schematic diagram of a CTD method based sensor. Two temperature-sensitive resistors
(sensor elements RS and RM) are immersed in the medium. Sensor element RM assumes the
temperature M of the medium whilst heater resistor RH heats element RS to temperature S. As a
function of the medium, the temperature differential
= S - M is preselected as a reference
variable by the CTD control with ∏ characteristics and is kept constant. The required calorific
power is a function of mass flow so that the control variable y of the control can be used for
evaluation.

The measuring system generally implies defined flow conditions, to establish the flow characteristics

pipeline, such as distances before and after the monitoring head, before or after any bends and
changes in pipe diameter, mounting attitude of the monitoring head (e.g. immersion depth), and
any restrictions caused by turbulent or asymmetric flow be considered.

As a result of the relevant physical properties and the characteristics of the monitoring head, any
variations of control variables will be very small and nearly linear in the event of high flow velocities,
whereas with low flow velocities there will be a high signal variation with resultant high nonlinearity. By setting the interpolation trim points close enough, the error can be kept below 1% over
wide distances of the measuring range.

If too high a temperature differential has been selected for the heater control to indicate, this is

It is thus verified and ensured when starting the calibration that the flow characteristics can

4.2.4 Zero point, directional discrimination and upper characteristic curve value
4.2.4 Zero point, directional discrimination and upper characteristic curve value
The zero point of the characteristic curve and the zero point of flow need not be identical. If the
zero point of the characteristic curve - lowest trim point - is above the zero point of flow, the
characteristic curve is linearly extrapolated down by 10% MBE (= upper measuring range value)
so as to extend the calibration range of the FC01-Ex.
However, the extrapolation is only effected to the theoretical zero point as the measuring system
does not operate in a direction-selective way.
If the zero point of flow and the zero point of the characteristic curve are identical, the control
variable should be increased by 300 to 400 digits to suppress the convection-dependent variation
of the zero point.
In the same way that the calibration range can be extrapolated downward by 10% MBE, so can
the upper calibration range be extrapolated by 10% MBE above the upper trim point. Error
indication because of minor over limits of the upper calibration range values can thus be eliminated.
The extended characteristic range will then be fully available when determining the analogue output,
the limit values and the bar graph.

digits.* Preloading the setting value for the lower trim point with that value obviates the need
for passing through a wide setting range (timesaving benefit).
* Provided the temperature differential has been selected appropriately (see para. 4.2.1 for
recommended values).
2. Linear preloading of interim values for velocity and control variable
As a result of parasitic heat transfer points a big part (approx. 50%) of the heating power is
not transported through the medium but rather through the housing and the electrical
cables. The heating power control variable with zero flow has already a value above 25,000
digits.* Preloading the setting value for the lower trim point with that value obviates the need
for passing through a wide setting range (timesaving benefit).
* Provided the temperature differential has been selected appropriately (see para. 4.2.1 for
recommended values).
2. Linear preloading of interim values for velocity and control variable
The calibration range left between the last addressed and established trim point and the zero
point is linearly divided among the remaining trim points. This applies both to velocity quantities
and control variables. It generally ensures that only a small calibration range needs to be
passed (provided that 1. has been satisfied).
In this operating mode - new curve - an already existing curve (old curve) would be deleted.
If the new curve is completely entered by hand, it is necessary to enter the TK reference
temperature (see 5.1.1.4.7) when quitting the menu.
The TK reference temperature is the medium temperature at which the curve was established under normal operating temperature conditions.
If the calibration of a new curve is made selecting temperature differences which are essentially
smaller than the values recommended, the zero point on the characteristic curve will be
displaced towards smaller control variables. It may happen then that the first trim value is
below or on the preloaded zero point value, in which case the software will provide that the
initial values for further control variables are below the established preceding value.
Technical implementation of customer calibration
The zero point of the characteristic curve and the zero point of flow need not be identical. If the
zero point of the characteristic curve - lowest trim point - is above the zero point of flow, the
characteristic curve is linearly extrapolated down by 10% MBE (= upper measuring range value)
so as to extend the calibration range of the FC01-Ex.
However, the extrapolation is only effected to the theoretical zero point as the measuring system
does not operate in a direction-selective way.
If the zero point of flow and the zero point of the characteristic curve are identical, the control
variable should be increased by 300 to 400 digits to suppress the convection-dependent variation
of the zero point.
In the same way that the calibration range can be extrapolated downward by 10% MBE, so can
the upper calibration range be extrapolated by 10% MBE above the upper trim point. Error
indication because of minor over limits of the upper calibration range values can thus be eliminated.
The extended characteristic range will then be fully available when determining the analogue output,
the limit values and the bar graph.
