CoM4 – Functional and End-of-Line Testing Systems
The versatile flow measurement device of the CoM4 family automates the dynamic and precise measurement of volume and mass flows of air and gases. Through sophisticated correction and reference calculations, as well as years of experience in the mathematical areas of gas physics, the CoM4 systems are capable of equipping with extensive functional tests. This allows geometric sizes or functional processes to be accurately mapped and evaluated using gas flow measurement.
The CoM4 flow measurement device is available in various versions and housings, from panel-mounted devices to 19″ rack modules in IP20, as well as splash-proof in IP54. Thanks to its modular design, precise sensors, and flexibly configurable evaluation software, it adapts seamlessly to a wide range of testing and measurement requirements. The associated flow measurement technology can be composed of different standards and can be set up either within the rack or externally on mounting plates.

Determination of geometric factors with Laminar Flow Elements
The CoM4.GEO functional testing system enables highly precise and dynamic measurement of geometric properties in optically inaccessible areas. The prerequisite for correct functioning is that the cross-section to be measured must be the narrowest constriction in the measurement path.
The measurement principle here is to achieve and limit the flow rate through the speed of sound at the narrowest cross-section. Additionally, corrections are made for ambient conditions, ensuring reproducible use.
For flow measurement in this configuration, a measuring path with one or more Laminar Flow Elements is used. All sensors used are delivered calibrated – also with a DAkkS-accredited calibration certificate if desired. Operation and result display are usually performed via a 4-inch touch display or provided browser software. Results are determined at up to 100 Hz and can be graphically displayed on the display.
- Highly precise determination of geometric properties
- Correction and reference calculations for reproducible measurement operation independent of ambient conditions
- Delivery with adaptation and master parts for determining a diameter in micrometers if required
