Krohne H250 variable area flowmeter

The Krohne H250 variable area flowmeter with M40 indicator is suitable for the flow measurement of liquids, gases and saturated vapour in the process industries and has a modular design that allows it to be adapted to the needs of any application. It is available for use in both horizontal and fall pipes as well as in the standard installation upright in rising mains.

The construction of the H250 M40 means that it can be either intrinsically safe or supplied in an explosion-proof casing, thus making it possible to comply with different regional explosion protection strategies with one device. In addition, its sturdy design ensures high resistance to pressure, temperature and media, and that it stands up to extreme application and environmental conditions.

The all-metal flowmeter has recently been approved with the North American approvals for the ignition protection types IS and non-incendive, bringing the device to more than 30 approvals worldwide for hazardous gas and dust areas, including ATEX, IECEx, usFMc, NEPSI, INMETRO, KGS, GOST-R and PESO/CCOE. Given this, the device is suitable for large international companies that need the respective local approvals, as well as OEMs looking to fulfil the requirements of different customers with one device.

The device can easily be upgraded with one or two limit switches (NAMUR, transistor or reed), a 4-20 mA signal output with HART, a graphical LCD with totaliser and pulse output or a digital, bus-powered communication interface according to FOUNDATION Fieldbus or Profibus PA - on-site without process interruptions.
