4. Installation
Variable area flow meters are only suitable for vertical installation, where the direction of
flow is from bottom to top. For all other installation situations, appropriate pipe bends need
to be fitted in the existing pipeline in order to ensure vertical flow through the device from
below.
Before installing, remove all protective caps, transport locks and any foreign bodies found.
Pay regard to the correct spacing and exact alignment of the pipes at the point of
installation. For Type SGK: before installation, both free ends of the pipe additionally need to
be provided with pipe fittings.

4.3. Preparations for assembly
The SGK flow meter consists of a channel section in which the tapered measuring glass is
firmly held in place by the two connecting heads with or without integrated batching valve.
Preparatory work at the point of installation:
1. Shut off and secure the pipe system in accordance with regulations, and drain the
pipeline.
2. Any control equipment, particularly in the case of gaseous media, should be located
downstream of the measuring device.
3. If necessary, support the pipeline to prevent vibration from being transmitted to the
measuring device.
4. Clean the pipelines leading to the device by blowing or flushing them out before
connecting up the device.
5. Before installing, fit the two free ends of the pipe with appropriate connecting
threaded joints (see Section 10.1). The heads with vertical pipe connection on the
front of the switch panel are provided with internal threads.
Installation of the SGK requires a hole pattern on the switch panel in accordance with
the Table, Section 10.2, that matches the selected model (to take up thread G
and/or M on Items 5 and 6).
4.4. SGK installation
1. Remove the nuts (Items 5 and 6) on the back of the channel section, and position the
device on the switch panel in the holes provided.
2. Then fasten the device to the switch panel by fitting the nuts on the back of the
channel.
3. Connect the ends of the pipe at the installation point tothe SGK device using
appropriate sealing material.
5. Start-up
The device must be properly installed before it is started up.
1. Check all device connections.
2. To set the flow: pressurize the pipelines by slowly opening the shut-off valves (risk of
glass breakage!). On liquid service: carefully evacuate the pipeline.
3. Check the leak-tightness of all components and, if necessary, tighten down threaded
joints or screw connections.

6. Readings in operation
The flow value is read off from the scale on the glass cone at the top edge of the float. The
measured-value readings are only correct when the operating condition at the measuring
point (flowing medium, operating pressure and temperature) corresponds to the values
marked on the measuring glass. If operating conditions should differ, the measured value
must be corrected with the aid of the general float equation, which you will find in our
t
echnical documents.
Y
ou can also do the recalculation with the help of our conversion program given on our
home page: www.k
t
-web.de, Section “Physical Basics“.
7. Limit switches
7.1. MSK1/ MSK12/ MSKW
The limit switches consist of a limit switch (reed switch) that is switched over by the
magnet integrated in the float .The limit switch is guided in a guide slot in the protective
case and can be adjusted over the full measuring range. The reed switches have a bistable
characteristic.
Uncontrolled current and voltage peaks can occur in the case of inductive or capacitive
loads, e.g. from contactors or solenoid valves. Such peaks will also occur, depending on
cable geometry, where cables exceed a certain length. We therefore recommend using an
MSR contact protection relay, which is additionally available. This will increase the contact
rating and prevent occurrence of inductive and capacitive peaks, thus ensuring long service
life of the contacts.
Electrical data and limit values are specified in Section 10.4.
