The H250 M40 flowmeters, based on the variable area principle, are versatile and can be used for gases as well as conducting and non-conducting liquids. The sturdy all-metal version ensures high resistance to pressure, temperature and product, and can withstand extreme usage and ambient conditions. The device features a completely modular design enabling it to be individually configured for virtually any requirement, from pure analogue use without auxiliary power to integration into a fieldbus system. The H250 is available in nominal sizes DN15-DN100 in various materials and connection variants.
Typically, variable area flowmeters are installed upright in rising mains and the product must flow through them from bottom to top which can lead to extra expense. The H250 M40 on the other hand, offers freedom in terms of layout as there are special versions of the device that can be used for horizontal and even fall pipes.
All electronic components are designed to be intrinsically safe and non-sparking and can be used in gas and dust explosive areas. Optionally, the same components – with a safety lid – can be installed as devices in explosion-proof enclosures. In this way, a single device can comply with different regional explosion protection strategies. All product variants offer category IP66/IP67 protection.
