2.3.2. Product description

The METPOINT FLM thermal flow meter measures the volume flow, 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 offers 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-effective 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 flow. The first temperature sensor measures the current
process temperature, while the second sensor is electrically heated 40 K above the first sensor. As volume flow or mass flow
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 difference is directly proportional to the mass flow. As the mass flow
increases, the rising heat output is converted into corresponding measured quantity values. The METPOINT® FLM determines the
exact mass flow from these values plus the inside diameter of the pipe.
