Small inline flow meter (compressed gas in pipes from DN15 to DN50)
● Modular design ● Removal without disassembling the piping ● Analog, pulse, switching output ● Modbus RTU and M-Bus ■ EE741 is an inline flow meter specifically designed for accurately measuring and monitoring compressed gases and industrial gases in pipes ranging from DN15 to DN50. The principle of thermal measurement and the proven E+E thermal film sensor element provide the best long-term stability and fast response. With application-specific multipoint functionality, it is factory set to 7 bar (102 psi), allowing for excellent measurement accuracy even in low ranges. This enables reliable leak detection and corresponding energy savings. Additionally, it features an optimized structure for easy installation and maintenance. Measurement quantities: m3/h, m3/min, l/min, l/s, kg/h, kg/min, m/s, SCFM, ft/min, °C, °F Standard conditions (factory setting): 1013.25 mbar (14.7 psi), 0 °C (32 °F) (configurable) For further details, please contact us.
