2.3.2. Product description

The METPOINT FLM thermal flow meter measures the volume flow, 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 efficiency. By measuring the
actual flow 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 configure their system systems and components for improved efficiency.
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 flow. The first 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 first sensor. As the mass or volume flow increases, the temperature sensors would normally cool off, but the electric heater
of the second heater prevents that from occurring.
The electric energy required to maintain the temperature difference is directly proportional to the mass flow. As the mass flow
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 flow.
