By means of a separate power supply that can be connected to either 12 V DC vehicle batteries or to a 220/230V AC domestic electric net the airflowmeter becomes independent from any vehicle ECU and can be used for applications of engine dynanometers, test beds, ventilation ducts, fuel cells, stationary engines, CHP, etc. To set-up such a measuring device the airflow sensor (part.-no.50000e), a connector kit (50020e) and this electronics named FlowSupply (part-no. 87000e) are required. The installation is very simple. The airflowmeter has to be mounted in the tube with airflow. Connect the cable to the sensor and the FlowSupply. Plug in the voltage supply to the 220/230 V net. Ready! The output signal 0-5 V DC can be read by any voltmeter and programmable logic controller.
