SEMTECH EFM-HS

Sensors’ High Speed Exhaust Flow Meter, the SEMTECH EFM-HS, replaces our EFM 2 and adds exciting capabilities and features to the product line. With a sampling rate of up to 2500 Hz and four, dual stage differential pressure transducers, the EFM-HS accurately measures every forward and reverse flow pulsation from idle to maximum flow rate, and properly accounts for these pulsations in the exhaust flow determination. This is a tremendous advantage over low speed exhaust flowmeters which are susceptible to measurement error from high frequency pulsations. The EFM-HS also offers a long list of other performance enhancements and convenience features that set it apart from the competition. Can be used either on-board or in a test cell.
