Ultrasonic Exhaust Flow Meter
EXFM-ONE employs an ultrasonic method for measuring exhaust gas flow rates directly from a vehicle or engine. The unit can be used for various applications such as real time mass measurement of raw exhaust gas combined with MEXA-ONE (Motor Exhaust Gas Analyzer), or for Particulate Matter/emission measurement combined with partial flow dilution system such as MDLT (Partial Flow Dilution Tunnel) or BMD (Bag Mini Diluter). Fuel consumption evaluation is also available when EXFM-ONE is paired with an optional air-to-fuel ratio (AFR) analyzer.
HORIBA ONE Series measurement devices such as MEXA-ONE and EXFM-ONE employ the newly developed software platform “HORIBA ONE PLATFORM”. The new platform enables the user to manage measurement and quality check results of EXFM-ONE and other devices on one single display. This single user interface increases efficiency and optimizes user control over the entire testing process.
