The EE771 thermal flowmeter from E+E Elektronik measures mass or volumetric flow of compressed air, nitrogen, oxygen, and other non-corrosive gases. It uses a hot-film sensor element which has been proven over several million installations in the automotive industry, with a turndown of 400:1. The mounting arrangement in combination with a ball valve simplifies installation and allows the sensor to be exchanged in seconds without disconnecting the measuring line. The two outputs can each be configured as analogue (current or voltage), switching, or pulse outputs for totalizing. A USB interface allows users to set up the flowmeter for specific measuring tasks.
