11 APPLICATIONS
The M&C flowmeters FM-2K and FM-200K-H(/FA) are used in analysis technique to control gas flow
up to an operating temperature of 180 °C.
Depending on the flowmeter glass tube, ranges from 16 l/h to 800 l/h can be realized.
12 DESCRIPTION
The M&C flowmeters FM-2K and FM-200K-H(/FA) consist of a vertical cone shaped glass tube with a
free movable float ball inside. The sample gas, flowing from the bottom to the top, lifts the float ball as
far as an annular gap appears between the tube wall and the float ball and the forces on the ball are
compensated. The position of the float ball is related to a scale on the flow meter tube. The FM-2K is a
basic heat resistant version for installation in heated systems.
The electrically heated version FM-200K-H(/FA) is equipped with an integrated needle valve and is
fixed on a mounting plate, decoupled from heat and covered with an insulated enclosure. The heater
consists of a heating element with high capacity. The temperature is adjustable on the integrated
thermostat up to 180 °C with high temperature limiter and low temperature alarm.
The window of the heat insulated enclosure guarantees a proper reading-out.
The electrical connection box with integrated thermostat is installed outside the enclosure on the
mounting plate. A flow control is possible consisting of fibre-optical light guides FO1, the sensor head
FA2-H and the pre-amplifier K-FA-H which is installed on the mounting plate as well. The electronic
controller FA... (option) has to be mounted externally. – See data sheet 5-6.10.2. –
In order to avoid cold spots, the connecting fittings are equally heated by means of double-ended
thermal conducting jaws. The electrically heated sample lines type 3/4/5-N/M/H – see data sheet 2-6.1
– are fixed with mounting brackets.

WARN I N G!
When connecting the equipment, please ensure that the supply
voltage is identical with the information provided on the model type
plate.
NOTE!
Attention must be paid to the requirements of IEC 364 (DIN VDE
0100) when setting high-power electrical units with nominal
voltages of up to 1000 V, together with the associated standards
and stipulations.
A main switch and matching fuse must be provided externally!
The main circuit must be equipped with a fuse corresponding to
the nominal current (over current protection), for electrical details
see technical data.
16 ELECTRICAL CONNECTION
Remove the lid of the electrical connection box. The electrical connection layout is located in
the lid.
Insert the mains cable (min. 3 x 1.5 mm²) through the cable gland and connect to the
appropriate terminals.
Insert the signal cable through the cable gland and connect to the appropriate terminals.
Screw lid back on.

17 STARTING
Before starting up check whether the mains power supply voltage corresponds with the
information stated on the type plate.
Switch on mains power supply.
The total heating-up time is approximately 30 min. The flowmeter then is ready for operation

NOTE!
The safety instructions specific to the plant and process are to be
consulted prior to any maintenance work!
WARN I N G!
Aggressive condensate is .
Wear protective glasses and proper protective clothing!
High surface temperatures! Wear protective gloves!
NOTE!
Prior to carrying out maintenance work on electrical parts, mains
voltage should be disconnected from all poles!
This also applies to any external control circuits, which may be
connected.
18 MAINTENANCE
It is difficult to give any recommendations as to a particular maintenance cycle. Depending on your
process conditions, a meaningful maintenance cycle must be elaborated for the specific application.
Check from time to time, if the flowmeter glass is soiled.
To clean the flowmeter glass remove cover lid.
Unscrew the aluminium lid.
Disconnect the thermal conductivity jaws on the top and at the bottom of the flowmeter in two
parts by loosening the screws, two each.
Disconnect the 2 sample lines.
Disconnect the tube at the top of the flowmeter.
Take out the flowmeter including needle valve.
Loosen the 3 hexagon screws on the upper and lower adapter, until you can pull them out.
Pull out the glass, check and clean it.
Check O-rings on top and bottom and change if necessary.
Assemble the flowmeter in reverse sequence.
