Magnetic Inductive Flowmeter
Klinger LDG is a magnetic inductive flow meter for measuring flow on liquids
with electrical conductivity.
The measurement principle is based on Faradays law on magnetic induction, it
says, that an electrical voltage will be induced, when a conductor passes a
magnetic field.
In the magnetic inductive flow meter is the liquid the electrical conductor,
and the induced voltage directly proportional to the velocity of the liquid.
The program is primarily for application in water, wastewater, the
refrigeration and energy sector, but can also used within a large number of
industrial tasks.
The sensor part is fully welded, and very stable at the same time as it is
insensitive to interference.
The construction is supplemented with a transmitter housing in IP67, a design
that make the meter suitable for use in harsh Environments.
With Klinger LDG meter we offer you:
- High measurement accuracy in a large measuring range
- A maintenance-free measurement without moving parts
- A measurement that is independent of temperature, density, viscosity, concentration and conductivity.
- Instantaneous flow
- Alarm status
- Unit of measurement
- Summarized flow
- Keys for operation
- Infrared sensor (option)
Klinger LDG replaces your current flow meter:
- Installation dimensions that comply with ISO 13359.
- Choose from several types of lining for best price / performance ratio.
- Choose between compact or separate design both types in IP67 design.
- Easy setting of measuring range and output signals without the use of special tools / programs.
- Backlit LCD display, which can be read even during difficult relationship.
- Supplied with Danish and English operating instructions
Technical data
A magnetic flow meter is made up of a piece of pipe made of something not
magnetic material. The tube is internally lined with a lining of non-
conductive material.
In the measuring tube, the two measuring electrodes are placed so that they
pass through the liner.
Lining and electrodes are the
only parts in contact with
the medium, and by choice must be taken taking into account that they can
handle:
- Aggressiveness of the medium
- Press
- Temperature
- Temperature shock

Ranges
Our magnetic flow meter can be set for measuring ranges from 0.3m / s up to 10m / s – it is recommended to choose a maximum flow between 4 and 6 m / s.
LDG can be delivered in dimensions up to DN 2.200mm – ask about measuring range for larger dimensions than stated.
Installation
Klinger LDG are built so that the installation dimensions are in accordance
with ISO 13359.
