FLOWSIC150 CARFLOW
|
|
| |
The FLOWSIC150 CARFLOW is a measurment system which has been specially adapted to the requirements of exhaust gas volume measurement on roll test stands and road test simulators in the automotive industry.
This compact measuring system can easily be connected to existing exhaust gas hose systems using quick connectors and is assembled on lockable rolling wheels for transportable use.
The volume flow is measured in the undiluted exhaust gas. For high accuracy measurements the instrument is available in a multi-path configuration (3 and 4 ultrasound measuring paths). The 4-path version has an additional enlargerd measuring range.
Integrated sensors for pressure and temperature determine these parameters directly in the measuring cell and are used for calculating and outputing the exhaust gas volume in the normalized state.
