The EE771, EE772, and EE776 thermal flowmeters from E+E Elektronik GmbH, Engerwitzdorf, Austria, record the mass flow or corrected volume flow of compressed gases such as air, nitrogen, helium, carbon dioxide, or oxygen in your supply network, regardless of pressure or temperature. Measurements can be carried out in pipes of DN15 (1/2 in.) to DN300 (12 in.) and with an operating temperature of 16 or 40 bar. The EE776 has a patented nonreturn protection device, the EE772 has a hot tap valve, and the EE771 has a ball valve mounting fitting. All flowmeters can be installed and removed quickly in their operational state for periodic QC and calibration. Two signal outputs can be configured as a current or voltage output, switching output, or pulse output, depending on the application. An integrated bus output is optional.
