The H250 metal variable area flowmeters cover the entire range of requirements of the process industry. The modular device design and flexible production structure form the basis for application and customer-based device versions.
The basis of the H250M40 is its purely mechanical design. Additional electronic modules can be added or replaced at any time without interrupting the process. This way, the functionality of the device adapts to any changed requirements. From analogue flow measurement without auxiliary power up to digital integration into a fieldbus system.
Simply screw off the cover, insert the module until it clicks, screw the cover back on and that's it. It is just as easy to replace the measuring scale in the event of a change in application.
