Flowmeter has achieved more than 30 hazardous gas and dust area approvals worldwide
KROHNE, Inc. announces the H250 variable area flowmeter with M40 indicator, suitable for the flow measurement of liquids, gases and saturated vapour in the process industry, with a unique modular design that allows it to be adapted to the needs of any application. Unlike traditional variable area flow meters, the H250 M40 is available for use in both horizontal and fall pipes as well as in the standard installation upright in rising mains.
The innovative 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 just one device. In addition, its sturdy design ensures high resistance to pressure, temperature and media and stands up to extreme application and environmental conditions, giving it high reliability at an affordable price.
The all-metal flowmeter has recently been approved with the North American approvals for the ignition protection types “intrinsically safe” (IS) and “non-incendive” (NI), 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 ideal for large international companies that need the respective local approvals, as well as OEMs looking to fulfil requirements of different customers with just one device.
The device can easily be upgraded with 1 or 2 limit switches (NAMUR, Transistor or Reed), a 4…20mA 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 standard onsite without process interruptions.
