Start up
2 Start-up
2.1 Standard device
When startin up the device, the followin points must be observed:
● Ensure that the actual operation conditions (pressure, temperature) do not exceed the limits
which are iven on the nameplate of the device
● Avoid float impacts!
Therefore it is recommended to start up with a closed shut-off valve to be opened slowly. The use
of solenoid valves is not recommended.
● When measurin liquids, the pipes must be vented slowly to prevent shock pressure due to as
bubbles.
● When measurin ases, the pressure must be increased slowly in order to prevent hi h shock
pressure.
● Durin start-up of new systems, residual materials may be carried in the medium and could
adhere to the float. In such cases it is recommended to clean the instrument after a relatively
short period of operation.
● When operatin the flowmeter at low flowrates, the device has to start-up with a hi h flowrate to
allow the float to level out. This will ensure measurements within the specified accuracy class.
Special issues for easuring gas flow:
● Valves have to be installed downstream of the device if p
abs
>1.013 bar and upstream of the
device if p
abs
=1.013 bar (free outflow).
● Install a throttle just downstream of the device to prevent compression oscillations durin
measurement.
● Ensure that the operatin pressure for the flowmeter corresponds to the calibration reference
pressure to avoid erroneous measurements.
Float da ping
A float dampin is recommended
● in eneral for measurin ases
● where pipin vibrations can not be avoided
It is also stron ly recommended in the case of:
● applications where air bubbles in the medium cannot be avoided
● possibility of shock pressure in the pipin , e. . due to rapid throttlin or process shut-off
● turbulence, pulsations, etc. which could lead to vibrations of the flowmeter
● rapid pressure build-up in the pipin

BA RE 250 EN 18-01 www.mecon.de Pa e 7 / 32
Start up
2.2 Device with current output (MEM)
The ma neto-electrical measurin transducer (MEM) is factory-set when it is delivered to the
customer.
After applyin the supply volta e to the device, initially the current output will be about 3.5 mA
to 4 mA for a few seconds. After that a current correspondin to the pointer deflection will flow.

Important!
Due to the influence of the float magnet, the MEM transmitter will only
output the correct current if the pointer position is caused by the float.
Turning the pointer manually will cause incorrect values, but it is suitable
for testing the unit.
2.3 Device with li it switches
The limit switches can be set over the entire measurin ran e by varyin the position of the limit
pointers.

Important!
Unless otherwise specified by the customer, the factory set value for the
switching point on versions with one limit switch is about 0% of URV
and for devices with two limit switches it is about 20% / 80% of URV.
To set the limit switches at the desired position the followin steps have to be observed:
● Unloosen the two small fixin screws (2) before movin the pointer (1).
● Move the pointer to the desired position.
● Ti hten the screws to fix the pointer.

3.1 Notes on installation

Information !
All instruments are carefully checked for functional capability before
shipment. Upon receipt of the device please carry out a visual inspection
of the outer packing for damage or improper handling.
Please contact the delivery carrier if you discover any defects. In such
cases a description of the defect, the type and the serial number of the
device are needed.

Information !
Unpack the equipment with care to prevent damage.

Information !
All instruments are carefully checked for order conformity.
Please check the delivery for completeness using the packing list. Please
examine the flowmeter nameplate to verify that the device was built
according to your order. Particularly check devices with electrical
components for the correct supply voltage.
3.2 Installation
Below the essential points concerning installation are described and have to be observed:
● Remove the transport securin device from the fittin .
● Prior to the installation verify that the float slides smoothly in the fittin without cantin or
deadlockin . The pointer must follow the float movement smoothly.
● Verify that all accessories such as sprin stop, as/fluid dampin are still correctly fixed in the
fittin .
● In the zero position (no flow) the pointer must be at the marked reference point (first line on
the scale). When movin the float manually to the end position, the pointer must be above the
final value of the scale.
● The flowmeter must be installed vertically – flow direction from bottom to top. For installation
recommendations refer to uideline VDI/VDE 3513 Part 3.
● The installation in the pipin must be tension-free – therefore the pipin must be positioned
parallel and ali ned with each other.
● Avoid a corrosive atmosphere –provide ventilation where necessary.
● Ensure a sufficient distance of at least 200 mm to ma net-influencin parts such as solenoid
valves or ferroma netic components e. . steel brackets.
● Observe a lateral distance of at least 300 mm between two devices mounted next to one
another. The distance can be reduced by mountin the devices sta ered by the len th of one
device. To eliminate doubt the influence can be tested by movin the instrument up and down

BA RE 250 EN 18-01 www.mecon.de Pa e 9 / 32
Installation
ca. 200 mm at a selected distance while observin whether the position of the pointer on the
display chan es.
● Specify the installation zone re ardin a reliable readin of the displayed values and adequate
spacin for servicin .
● An inlet run upstream and an outlet run downstream the device is not necessary in case of a
linear media flow profile. In cases of hi hly asymmetrical flow profiles, however, additional
measures (e. . inlet tracks, flow rectifiers) with a len th of at least 250 mm could be
appropriate to ensure the measurin accuracy.
● Avoid the installation of unilaterally constrictin fittin s upstream of the device.
● Ensure that the pipin is installed securely to avoid vibration or oscillation of the devices.
● The nominal width of the flowmeter and the connected pipin must be identically.
● Use connectors connectin bolts suitable for the particular device version (dimension, pressure
ratin ).
● Ensure that the clearance between the flan es of the pipin corresponds to the device
dimension in addition to two askets.
● Before connectin the device, blow or flush out the pipes leadin to the device.
● The surface rou hness of the flan e sealin areas must be appropriate for the used askets.
● The askets and bolts of the prescribed dimensions must be appropriate for the operatin
pressure, the temperature and the media.
● Do not use carbon steel ounting brackets for the device!
Additionally for devices with PTFE liner:
● Use askets which conform to the inner and outer dimensions of the raised face of the
flowmeter.
● Ti hten the screws crosswise to ensure the ti htness of the process connections. For ti htenin
torques please refer to Tab. “2.2 Ti htenin torques”.
● If the instrument is absolutely calibrated for a pressure exceedin 1.013 bar any valve is
usually installed at the rear of the flowmeter, at 1.013 bar absolute (free emanation) in front
of the instrument.
Special issues for easuring gas flow:
● Valves have to be installed downstream of the device if p
abs
>1.013 bar and upstream of the
device if p
abs
=1.013 bar (free outflow).
● Install a throttle just downstream of the device to prevent compression oscillations durin
measurement.
● Ensure that the operatin pressure for the flowmeter corresponds to the calibration reference
pressure to avoid erroneous measurements.
Tightening torques
The flan e bolts for devices with PTFE liner may be ti htened with the followin torques (acc.
uideline VDI/VDE 3513):

Tab 2.2 Ti htenin torques for devices with PTFE liner
Magnetic filters
To prevent a malfunction of the flowmeter caused by ferroma netic substances contained in the
medium (such as weld beads) a ma netic filter should be mounted in flow direction upstream of
the instrument.
This kind of filter is also recommended if such particles cannot be avoided in standard operation.
3.3 Operating principle
Like other devices of this series the variable area flowmeter RE 250 operates accordin to the
principle of flotation:
The measurin unit consists of a metal tube with a measurin rin in which a float can move up
and down. The media is flowin upwards throu h the tube and raises the conical float. Here the
annular ap enlar es until the equilibrium between the buoyancy force F
A
, the dra force F
S
and
the wei ht of the float F
G
is reached. The adjusted hei ht of the float is directly proportional to
the flowrate. The movement of the float is transmitted via a ma net inside the float to a
correspondin ma net inside the display unit outside of the measurin pipe.
