Product description

- Direct measurement of mass flow and temperature
- Low pressure loss
- Additional modules to increase functionality
- Simple installation with integrated ­measuring distance
- High measuring accuracy even in ­installations with a poor flow profile

Perfect for use in air consumption and air and gases flow measurement, as well as for compressed air operated tools and machines.

Multi-Point-Measurement Principle of Operation
The well-known and time proven measuring principle of thermal ­anemometry has been integrated into the new SCHMIDT® InLine Mass Flow Sensor, now with 4-point measurement.

The SCHMIDT® MPM Technology generates four measuring values in parallel. Processing these values by intelligent algorithms it is possible to achieve greatly improved and reliable measurements, even with insufficient inlet and outlet distances.

Four well-protected and streamlined mass flow elements have been strategically positioned inside the measuring section. The radial arrangement of the four measuring points combined with the associated signal processing means that even poor flow profiles can be reliably and more accurately measured.

Two parallel positioned sensor carriers integrated into the measuring section of the sensor carry the four high precision and fully independent flow sensor elements. A temperature sensor element, used to determine the air/gas temperature, has been placed on a third carrier positioned between them.
Each of the four flow sensor elements are electrically heated to a distinct fixed temperature above the temperature of the medium. The power required to maintain this positive temperature differential (over temperature) is processed to determine the mass flow and the sensor sends out a linear current / pulse signal proportionate to the flow. The great advantage of this measuring principle is that no additional pressure or temperature measurement of the medium is required.
