Ee741 modular design

The EE741 in-line flow meter can be flexibly adapted for any measuring task. With just a single transmitter and three different gauge mounting blocks, the consumption of compressed air and technical gases can be determined in pipe diameters DN15, DN20 and DN25.  The thermal measuring principle and the well proven E+E hot film sensor element lead to best long-term stability and fast response time.  Outstanding measuring accuracy, even in the lower measuring range is achieved by an application-specific multi-point factory adjustment performed at 7 Bar (102 PSI). This allows reliable leak detection and corresponding energy savings. The construction of the EE741 flow meter is optimised for easy installation and maintenance. 

• Modular design
• Removal without dissasembling the pipework
• Application-specific adjustment under pressure
• Exceptional price/performance ratio
• Analogue, pluse and switching output
• Modbus RTU and M-Bus
• Integrated consumption meter
