Delivery time:Delivery time on request
The H250/M40 flowmeters set new standards in variable area technology. They combine proven flow measurement technology for gases and liquids, which in its basic version requires no auxiliary power, with state-of-the-art technologies such as Foundation Fieldbus communication. The device functionality can be scaled modularly. There is also freedom of choice in the explosion protection strategy - intrinsically safe or flameproof enclosure.
