METPOINT® FLM
Sensor technology for flow measurement
One compressor in three runs solely to compensate for air losses – unnecessary compressed air consumption whose costs are largely avoidable. Precise measurement of the current flow rate is an effective solution. It forms the basis for numerous important analyses, documentation and decisions. With the METPOINT FLM SF13 and SF53, BEKO TECHNOLOGIES offers precise monitoring at the point of use.
Pipe diameter
¼ to 10 inches
Operating pressure
up to 16 bar
Supply
18 to 36 VDC
Measuring principle
calorimetric
Optimise compressed air consumption in your company
If you know your compressed air consumption, you can reduce it in a targeted way. The METPOINT FLM measures the flow rate directly in the compressed air line using the calorimetric measuring principle.
Flow meter with display
The display and configuration menu allow all measured values to be shown and sensor settings to be made
Flow meter with LED
The more economical LED version indicates when a new calibration is due (annually). Please note: the sensor can only be configured during production or later using the BDL data logger
How flow measurement works
For flow measurement, two temperature sensors are placed one behind the other in the direction of flow of the compressed air. The first sensor records the current process temperature of the compressed air, while the second sensor is heated electrically so that it is always 40 kelvin warmer than the first.
As the volume or mass flow increases, the sensors cool down, causing the electric heating of the second sensor to counteract this. The electrical energy required to maintain this temperature difference is directly proportional to the flow rate. This means that as the flow rate rises, the required heating power also rises, and this value is then converted into corresponding measurement data.

Calibration service for your METPOINT® FLM
Transducers and transmitters are frequently exposed to mechanical stress and temperature fluctuations. This can lead to a decrease in the measuring accuracy of the sensors and cause what is known as “drift”, which distorts measurement results and can therefore impair production or product quality.
BEKO TECHNOLOGIES offers a comprehensive range of calibration services for flow sensors, pressure dew point transmitters, pressure transmitters and analysers. These calibrations are carried out according to a specified BEKO TECHNOLOGIES procedure and correspond to an ISO calibration. ISO calibrations are comparative measurements of external test items against in-house reference instruments that are traceable to national standards. All calibration procedures meet the requirements of the DIN EN ISO 9001 quality standard.
Frequently asked questions
What do I use the METPOINT FLM for?
It measures the flow rate at the point of use. This lets you monitor compressed air consumption, identify savings potential and determine leakage volumes.
How does the METPOINT FLM measure?
Two temperature sensors sit one behind the other in the flow. The second is kept constantly 40 kelvin warmer than the first. The heating power required for this is proportional to the flow rate.
Which measured variables does the sensor display?
As standard, flow rate in m³/h, consumption in m³ and flow velocity in m/s.
Which pipe sizes is the METPOINT FLM suitable for?
For pipe diameters from ¼ to 10 inches. The operating pressure can be up to 16 bar, or optionally up to 50 bar with the SF53.
Can I install the sensor without shutting down the system?
Yes. Installation and removal are possible under pressure, and the sensor is Plug & Play.
What is the difference between the display and LED versions?
With the display, you show all measured values and make settings directly on the device. The more economical LED version only indicates when a new calibration is due. It is configured during production or later via the BDL data logger.
How accurate is the METPOINT FLM?
The accuracy is ± 1.5 % of measured value ± 0.3 % of full scale.
How do I connect the sensor to my control system?
Via the 4 … 20 mA output, via RS485 (MODBUS RTU) or via the volt-free pulse output with one pulse per m³ or per litre.
How often does the sensor need to be calibrated?
Annually. BEKO TECHNOLOGIES calibrates according to a defined procedure that corresponds to an ISO calibration and is traceable to national standards.
