Measuring principle
If a medium flows with sufficient velocity through the horizontally
or vertically arranged measuring chamber. If the KPM fitting, the
paddle will swivel around the axie until the force of the medium
and the opposing force of the paddle surface plus the spring
tension establish equilibrium. The angular position or the position
of equilibrium of the paddle in the measuring chamber is the
measure for the flow. The encapsulated ring-type permanent
magnet at the end of the paddle axis then transmits this position
to the scale and the optional electronic evaluators through the
magnet tracking indicator system.This happens safely and without
packing glands. The flow rates shown on the scale only apply to
the calibrated medium or to a medium with the same physical
characteristics.
Introduction
KPM flowmeter is suitable for measurement of liquid in pipes.
The special advantage is that it can be used for all directions

of flow. It can show the current flow rate in volume or mass per
unit in time.
Applications: flow measurement, dosing, monitoring, adjusting
and control of liquid products. The meter’s design makes it
ideal for processes under difficult and adverse operating
conditions.
1. Fitting
The devices are available with additional electrical equipment
for process monitoring and control.

Installation
Installation conditions
The KPM can be installed vertically or horizontally (according to the direction of flow indicated in the order). The nominal size of
the product line to be connected must correspond to the nominal size of the KPM. The best installation position is between loose
flanges。When installing the device between weld-on flanges, the flange hole pattern has to be turned so that the indicator unit is in a
horizontal position if the pipe arrangement is horizontal. The nominal size of the product line to be connected must correspond to the
nominal size of the KPM. Avoid fittings converging on one side directly in front of the device.
The adequate distance to ferromagnetic parts must be observed. During installation, the standard inlet section must be 5 x D
and the standard outlet section 3 x D.
We recommend that the lateral distance between two adjacently mounted devices be 300 mm. The devices can be mounted close
together if vertically offset by one device length. The minimum lateral distance for interfering steel parts should be 200 mm. In case of
doubt, check the interference by moving the device back and forth in the selected distance by about 200 mm and testing whether the
pointer position changes.
Select the mounting location so as to enable a reliable reading of the scale values. Please take note as well of the space
requirement for a possible disassembly of the device.
