product family features
• Includes a minimum of two sensors, a router and transmitter box with LCD display showing both temperature and air flow velocity or volume in either FPM, CFM or Meters per second or Liters per second.
• Easily field configured for any size fan.
• The transmitter box provides two isolate 4-20 mA analog linear signal outputs representing measured air flow and temperature and shares the same platform as our EAMP, electronic air measurement probes.

Family Description
Ruskin's EFAMS electronic fan-inlet air measurement station utilizes thermal dispersion technology combined with low-pressure drop aerodynamic sensors to measure the airflow at the highest velocity point in the system. This lower pressure drop equates to lower cost of operation over the life of the building when compared to other fan inlet devices. The unique design does not rely on measurement of 100% of the air entering the fan, only measurement of an air flow that we know will track the actual air flow through the fan. The benefit is a more accurate air flow measurement (taking into account system effects) without adding a significant energy penalty, typical of most aftermarket fan inlet air measurement devices.
