PTFM-1000
Overview
The Pitot Tube Flow Meter
The PTFM-1000 is used for the direct measurement of engine exhaust gas flow rate on engine and chassis dynamometer test systems.
The PTFM provides the exhaust flow rate without requiring a CVS for CO2 tracer or modification to the engine for air and fuel flow measurement. Meets the accuracy requirements of ISO 16183*.
* (+/- 1.5% of max fl ow or +/- 2.5% of reading, whichever is largest)
Features
BENEFITS:
- Eight sizes of flow tubes available for flow rates from 2 - 65 m³ / min
- Calibration Coefficients and Tube type stored locally on the tube to allow the interface to detect the correct tube and upload the correct Coefficients
- Exhaust Pressure Sensor (+/- 10 kPa gauge)
- Exhaust pipe connections/seals for high temperature operation (550 ºC)
- Quick Coupling for easy connection to the exhaust pipe
- Multiple data outputs (analogue, RS-232 or LAN) 10 Hz
- Three additional, user configurable data channels such as exhaust pressure, temperature
- Optional Remote Display module (max cable length 10m)
