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 eciency. By measuring the
actual ow to the various production units, operators are in a position to make decisions based on facts. At the same time,
the METPOINT® FLM lets them know whether there are any leaks in their system. The METPOINT® FLM thus provides all the
information operators need to correctly dimension and congure their system systems and components for improved eciency.
The device is equipped with a Modbus RTU(RS485) interface, a 4 ... 20 mA current output, as well as a galvanically insulated 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 mass or volume ow increases, the temperature sensors would normally cool o, but the electric heater
of the second heater prevents that from occurring.
The electric energy required to maintain the temperature dierence is directly proportional to the mass ow. As the mass ow
increases, so dies the heating power, which is then converted into the appropriate measured value. 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 “Conguration and operation” on page
27.
2.4.2. Model with LED
There is an LED on the top of the METPOINT® FLM housing, which is used to indicate the calibration time. The light ashes after
15 months to indicate there is an upcoming re-calibration. The ashing LED does not inuence measured values. The measurement
signal is still output.
The time interval can be adjusted as requested by the customer in the manufacturing plant.

3. Installation
3.1. Warning
DANGER Escaping compressed gas
Risk of serious or even fatal injury from contact with escaping compressed gas or from unsecured plant
components.
• Before carrying out any assembly, installation or maintenance work, depressurize the system. Such
work must be carried out by authorized specialist technical personnel only (see “Safety instructions”
on page 5).
• Use high-pressure protection above 145 psi to ensure safe installation and removal.
• Tighten the clamping sleeve with a torque of 14.75 ... 22.13 ft lb (wrench size 27).
• Use only pressure-resistant installation materials and suitable tools that are in proper working order.
• Before pressurizing the system, check all unit parts and repair them, if necessary. Open valves slowly
to prevent pressure blows during operation.
3.1.1. Requirements for piping
• Correctly dimensioned gaskets.
• Correctly installed and aligned anges and gaskets.
• Dierences in pipe diameters at joints should not exceed 1 mm. For more information, see ISO 14511.
• Clean, properly installed pipes.
3.1.2. Requirements for infeed / outfeed section
The following table shows the required infeed sections, depending on the direction of ow.

3.1.3. Turning the housing
If the direction of ow changes, the housing can be turned by loosening 4 grub screws with 0.059 in hexagon socket to the desired
position. Then tighten the grub screws again by hand.
NOTICE Risk of damage to device
• Ensure that the connecting pipes are correctly mounted and that the gaskets are installed properly.
• Then align the sensor in the direction of ow using the alignment aid.

EN Installation and operating manual
METPOINT®SF53 19
3.2. Installation
The sensor is installed by means of a ½, DN 15 ball valve (min. Ø 0.591 in).
Install the straight tting with the O-ring (G½ thread, wrench size 32) in the connecting nozzle. Ensure that the assembly is
pressure-tight.
Place the sensor head at the center of the tube and aligned 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 aligning aid. After the sensor is correctly positioned and aligned, tighten
the slotted spring pin with a torque of 14.75 ... 22.13 ft lb (wrench size 27).
When tightening the straight tting and the slotted spring pin, take care not to change the alignment of the sensor. Otherwise,
you might need to correct the sensor position and alignment.
The angle of the sensor should not deviate by more than ± 2° from the ideal position. Larger angles might result in inaccurate
measurement.
The high-pressure protection device (Art. No. 4025892) must be used above a working overpressure of >145 psi.
This allows for assembly under pressure and allows the sensor to be attached securely to the measurement point.
NOTICE Additional information
Further information on mounting the high-pressure protection device is available from the enclosed
installation and operating manual.
