4 Installation
Flap-type ow meters are suitable for installation in either vertical or
horizontal pipe runs. In vertical pipe runs, ow must be from bottom to top.
Make sure the pipes are correctly spaced and in true alignment at the
installation location for the ow meter. For connection of the KLA device, t
the open ends of the pipeline at the installation point with anges appropriate
to the ow meter.
Straight unimpeded pipe runs upstream and downstream of the meter’s
installation location should have a length equal to a minimum of 2 x DN.
4.1 Mounting position KLA
When the KLA is mounted horizontally with left/right or right/left ow direction,
make sure that the device is installed with the scale facing the front.
This position will ensure that the device functions properly (see Figure 1).
The device cannot function if it is installed with the scale facing upwards or
downwards (see Figure 2).
CORRECT:
The scale faces in front.

4.2 Installation KLA
For mounting, provide the connection anges of the KLA with suitable at
gaskets. The gaskets are not included with the ow meter.
Before installing, remove the transport lock from inside the device and t the
open pipe ends with appropriate connecting anges. Make sure the pipes are
in true alignment and the sealing faces spaced correctly. Install the device
in the direction of ow indicated by the arrow on the scale such that it is free
from stresses. Use gaskets made of rubber, PVC or Teon.

5 Start-up
6 Readings in operation
On the standard device, values are read o󰀨 at the pointer on the
aluminium scale. On the KLA GS version, the ow rate is indicated directly
by the ap. At the front and rear, the ow meter features in each case a pane
of hard glass. The ow rate is read o󰀨 from a scale attached to the front hard
glass pane on a level with the top edge of the KLA ap.
Measured values are correct only when the operating condition at the
measuring point (owing medium, operating pressure and temperature)
corresponds to the operating state data marked on the scale
The device must be properly installed before it is started up.
1. Check all device connections.
2. To set the ow: pressurize the pipelines by slowly opening the shut-o󰀨
valves. On liquid service: carefully vent the pipeline.
3. Check the leak-tightness of all components and if necessary, tighten
down threaded joints or screw connections.

7 Limit switches
The ow meter can be equipped with limit switches with preset switching
point to provide local indication with monitoring function. The switches have a
bistable characteristic.
The following devices are equipped with limit switches:
KLA Standard-IK with BI1-HS540-Y1 - 2-Wire, NAMUR
KLA Standard-IKS with BI1-HS540-AP6X - 3-Wire, PNP, NO
KLA V4A-IK with BI1-HS540-Y1 - 2-Wire, NAMUR
KLA V4A-IKS with BI1-HS540-AP6X - 3-Wire, PNP, NO
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, when cables exceed a certain
length. We therefore recommend using an MSR contact protection relay,
which can be additionally supplied. This will increase the contact rating and
prevent the occurrence of inductive and capacitive peaks, thus ensuring long
service life of the contacts.
Electrical data and limit values are specied in chapter 11.
7.1 Connection of limit switches
4. The connection is established via the two or three cable ends of the limit
switch.
Electrical connection of the device must be carried out in conformity
with the relevant VDE regulations (or equivalent national standards)
and in accordance with the regulations issued by the local power
supply utility.
1. Disconnect the plant from supply before connecting the limit switch.
2. Provide a protective circuit for the switches in keeping with their capacity.
3. Connect line-side fuse elements matched to consumption.

7.2 Setting the limit switches
The KLA is adjusted during factory assembly to the customer-specic
switching points.
If a new setting is required, the switching point can be changed by moving
the pointer vane.
The switching function can be reversed by specifying whether the pointer
vane rst enters or rst exits the slot sensor.
7.2.1 Preparation
In order to make the settings, the polycarbonate screen has to be removed.
1. First Remove the tensioning ring out of its groove, using a small
screwdriver.
2. Take the polycarbonate screen from the ring.
3. Make sure that the O-ring located under the screen is not lost! It secures
the scale space from dust and dirt ingress.
You have now access to the limit switches and the pointer vane.
7.2.2 Adjusting the limit switches
1. Manually move the pointer to the ow value at which the switching
operation is to be performed. Fix the pointer and make sure that the
pointer cannot move during the adjustment procedure.
2. Depending on the desired switching function of the limit switch and the
ow direction, turn the pointer vane until one of its edges reaches the
switching contact.
3. Check the switching point by moving the pointer through it manually.
7.2.3 Adjusting the switching function
The switching function of the contact can be set, depending on whether the
pointer vane moves into the contact or moves out of him, when reaching the
switching point.
2-wire BI1-HS540-Y1:
Pointer vane detected → Current consumption ≤ 1.2 mA
Pointer vane not detected → Current consumption ≥ 2.1 mA
3-wire BI1-HS540-AP6X:
Pointer vane detected → Signal output closed
Pointer vane not detected → Signal output open
