• From 10 bar, install a high-pressure protection element for safe installation and removal of the device.
• Do not operate the device in connection with ammable gases.
• Strictly adhere to the prescribed operating times and maintenance intervals.
• Observe the prescribed storage and transport conditions.
• Prevent condensation on the sensor element. Ensure that the air fed through the device is free of
droplets.

1.5. Intended use
The METPOINT® FLM is a thermal ow meter for the measurement of volume ow, consumption and ow velocity. By default, the
device is congured for the measurement of volume ow in m³/h, consumption in m³ and velocity in m/s.
• The METPOINT® FLM is primarily used in compressed air systems. On request, the sensor can be programmed by
BEKO TECHNOLOGIES GmbH for the measurement of other gases: nitrogen
• The device is not suitable for operation in potentially explosive or aggressive atmospheres.
• Protect the device against direct sunlight and heat radiation.
Operate the METPOINT® FLM only for the intended purpose and within the limit range specied in the technical data. Do not
operate the device with any media (uids, gas/vapour mixtures) other than those listed above. Any other use of the device is
deemed improper and poses a risk to persons, property and the environment.
1.6. Warranty and liability
All warranty shall be voided, if the METPOINT® FLM is used improperly, for a purpose other than the intended or is operated
outside the limits specified in the technical data. In such cases, the manufacturer shall also reject any liability for damages.
Improper operation includes:
• Incorrect installation, commissioning or operation; insucient maintenance
• Operation with defective components
• Non-compliance with the instructions in this document, in particular the safety instructions
• Modication of the device
• Non-compliance with the prescribed maintenance intervals
• Use of third-party spare parts that have not been approved by the manufacturer

2.3.2. Product description
The METPOINT® FLM thermal ow meter measures the volume ow, which forms the basis for intelligent energy management.
It can be used to identify potential savings, overloads and weak points in a system to improve its eciency. By measuring the
actual ow to the various production units, operators are in a position to make decisions based on facts. The METPOINT® FLM
also indicates whether there are any leaks in their system. The METPOINT® FLM thus provides all the information operators need
to correctly dimension and congure their system and system components for improved eciency. The device is equipped with a
Modbus RTU(RS485) interface, a 4 ... 20 mA current output, a galvanically isolated pulse output and an optional MBus interface.
2.3.3. Operating principle
Two temperature sensors are installed in series in the direction of ow. The rst temperature sensor measures the current process
temperature, while the second sensor is electrically heated to a temperature that is exactly 40 K above the temperature measured
by the rst sensor. As the volume ow increases, the sensors would normally cool, but the electric heater of the second sensor
prevents such a temperature drop.
The electric energy required to maintain the temperature dierence is directly proportional to the volume ow. This energy
consumption of the heater is converted into the relevant ow measurements. Taking into account the inside diameter of the pipe,
the METPOINT® FLM determines the exact mass ow.

NOTICE Additional information
For more information regarding the operation of the device, see „Conguration and operation“ auf Seite
24.
2.4.2. Version with LED
The METPOINT® FLM features a LED calibration indicator mounted at the top of the housing. After 15 months, the LED begins to
ash, indicating that the device needs to be calibrated. The ashing LED does not have any eect on the measuring process, and
the device continues to provide accurate measuring signals.
On request, the calibration interval can be adjusted at the factory.
