H250 with M40 indicator

The new standard solution for the process industry

The H250/M40 flowmeters are setting a new standard in variable area flowmeter technology. They combine tried and tested flow measurement with latest communication capabilities like Foundation Fieldbus. The functionality of the devices is modular extendable. The innovative construction allows a free choice of intrinsically safe or flameproof design.

The sturdy all-metal design, availabale in different materials, ensures high resistance to pressure, temperature and media and stands up to extreme application and environmental conditions. The new H250/M40 is the new standard solution for the process industry when costs and reliability are a factor.

Highlights indicator/transmitter M40

	Simple, low-cost installation: Measure and display without auxiliary power supply
