2.3.2. Product description
The METPOINT® FLM thermal ow meter measures the volume ow, which provides the base data needed for intelligent energy
management. This can be used to identify potential savings as well overloads or malfunctions and so optimise plant dimensions.
The assignment of consumption percentages to production units oers a basis for evidence-based decision-making. The
device also indicates the volume of compressed air lost to leaks in the compressed gas system. The METPOINT® FLM therefore
provides the data needed to match components properly and design cost-eective plants. The device is equipped with a Modbus
RTU(RS485) interface, a 4 ... 20 mA current output and a galvanically isolated pulse output, as well as an optional Mbus interface.
2.3.3. Basic operating principles
Two temperature sensors are installed in series in the direction of the ow. The rst temperature sensor measures the current
process temperature, while the second sensor is electrically heated 40 K above the rst sensor. As volume ow or mass ow
increases, the temperature sensors cool down, so the electrical heating of the second sensor must increase in output.
The electric energy required to maintain the temperature dierence is directly proportional to the mass ow. As the mass ow
increases, the rising heat output is converted into corresponding measured quantity values. The METPOINT® FLM determines the
exact mass ow from these values plus the inside diameter of the pipe.

NOTE Additional information
For more information about operation, see “Conguration and operation” on Page 27.
2.4.2. Model with LED
A calibration reminder LED is mounted on the top of the housing of the METPOINT® FLM. After 15 months have elapsed,
recalibration becomes due and is indicated by the LED ashing. The ashing LED has no eect on measurement data. The
measurement signal is output as before.
The reminder time interval can be adjusted to customer requirements at the manufacturer's works.

NOTE Deviating measurements
The above values are required minimum values (presented in a
simplied form). If the recommended settling sections cannot
be implemented, the deviations in measurements made may
become more frequent or very frequent.

3.1.3. Turning the housing
If the direction of ow changes, the housing can be turned to the required position by undoing the 4 threaded pins with a 1.5 mm
hex key. Align the housing as required and then tighten the threaded pins so they are hand-tight.
NOTE Risk of damage to device
• Ensure that the connecting pipes are correctly mounted and that the gaskets are installed properly.
• Then use the alignment tool to align the sensor with the direction of ow.

3.2. Assembly steps
The sensor is installed by means of a condensate drain ½, DN 15 ball valve (min. Ø 15 mm).
Install the straight tting with the O-ring (G½ thread, spanner size 32) into the connecting nozzle. Ensure that the installation is
pressure-tight.
Place the sensor head at the centre of the tube and align it to the direction of ow. To do this, the sensor tube is equipped with
a depth scale, arrows indicating the direction of ow and an alignment tool. After the sensor is correctly positioned and aligned,
tighten the adapter sleeve with a torque of 20–30 N·m (spanner size 27).
When tightening the straight tting and the adapter sleeve so they are pressure-tight, take care not to change the sensor
alignment. Otherwise, you may need to check and re-adjust the sensor position (depth) and alignment.
The angle of the sensor should not deviate by more than ± 2° from the ideal position. Larger angles may result in inaccurate
measurement.
The high-pressure safety device (art. no. 4025892) must be used with operating pressures >10 bar.
This enables pressurised installation and the safe attachment of the sensor to the measuring point.
NOTE Additional information
Additional information about assembly of the high-pressure safety device can be found in the enclosed
installation and operating manual.
