Krohne H250 Metal tube flowmeter

Krohne H250 Metal tube flowmeter Product Description  1.  H250  Krohne H250 Metal tube flowmeter   Hot sales Krohne Flow Meter/ Krohne Flow Meters H250 M40/M8/M9/M10 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 Unique modularity to adapt to customer-specific applications - limit switches (NAMUR, 3-wire transistor or reed contacts) - 2-wire analog output 4…20mA with HART - Foundation Fieldbus / Profibus PA interface - Graphical LC display with flow counter and pulse output Universal ex-concept: Flameproof and intrinsically safe Ingress protection IP66/68, IP69K, NEMA 4x/6 Any meter orientation possible: vertical, horizontal or in fall pipes Highlights H250 measuring cone   Sturdy stainless steel construction for high operating pressure up to 3000 bar and extreme process temperatures from -200°C to +400°C Optionally available with PTFE/ceramic liner for acids and alkalis High application security, even with extremely small flows Excellent long-term stability Upper limit of measurement for liquids: 10 to 120,000 l/h (water: 20°C) Upper limit of measurement for gases: 0.7 to 2800 m3/h (air: 20°C, 1.013 bar) Measuring range 10:1 (optional 100:1) Accuracy: 1.6 % according VDI/VDE 3513-2 (qG = 50%) Many different process connections Flanges as per EN (DN15-DN150), ASME and JIS Screw and clamp connections, welding ends et al. Special design for the food and pharmaceutical industry with EHEDG approval.     2. Options and variants 2.1Stainless steel indicator housing (H250/M9R)   For particularly rough environmental conditions, the M9 indicator housing is optionally available in stainless steel. This guarantees its reliable use in corrosive atmospheres caused by operational emmissions. When installed outdoors, external influences such as salt fog or contaminated precipitation no longer lead to corrosion.The stainless steel housing is equally well-suited for use in splash water zones such as in the food and luxury food industry.                     2.2FOOD & PHARMA (H250 F)                                                The only EHEDG-certified variable area flowmeter approved for used in the food and pharmaceuticals industry.Smooth stainless steel surfaces with a surface roughness of ≤0.8 µm or 0.6 µm of the wetted parts make deposition difficult and are very easy to clean.Combined with a design featuring no dead spaces or stagnation zones, micro-organisms have no chance to adhere and multiply.The measuring devices can be cleaned (CIP) and sterilised (SIP) in place. Suitable connections and FDA conforming materials for the food and pharmaceutical industry are available.               2.3 PTFE/ceramic liner for aggressive media   All wetted parts are made ofPTFE or ceramic and can thus be used for almost all acids and alkalis. Depending on the choice ofmaterial, the measuring device can be used up toa maximum temperature of 70°C / 158°F (PTFE) or 250°C / 482°F (ceramic).                                 2.4Versions for special installation positions (H250H / H250U)   Variable area flowmeters typically feature a vertically positioned measuring cone through which the medium flows from bottom to top, lifting a float against the weight. If the installation structure does not permit otherwise,versions for horizontal or inverted (from top to bottom) installation positions are used.The missing reset force of the variable area float weight is replaced by a spring.                         3 Indicator variants   3.1 Indication H250/M9 (modular) • Local indication without auxiliary power supply• 2 limit switches (NAMUR or 3-wire transistor) • 2-wire current output 4…20 mA with HART ® • Profibus PA interface • 6-digit flow counter withpulse output (non Ex) • Intrinsically safe Ex i (ATEX, FM, NEPSI)                               3.2 Indicator H250/M10 (integrated)   • Graphic display for measured value and counter display • 2 limit switches (NAMUR or open collector transistor) • 2-wire current output 4…20 mA with HART ® • 12-digit flow counter with pulse output and reset input • Explosion proof enclosure Ex d (ATEX, FM, CSA, NEPSI)                   3.3 Indicator H250/M8 (compact)   • Compact, space saving design • Intrinsically safe Ex i (ATEX) M8M • Mechanical indicator without auxiliary power • 2 limit switches (NAMUR) M8E • Electronic bargraph indicator • 2-wire current output 4…20 mA with HART ®               Krohne H250 Variable Area Flow Meter     Payment&The Delivery   Contact Us
