KROHNE electromagnetic flowmeter H250 M40 for Variable area flowmeter for liquids and gases

H250 M40

Variable area flowmeter for liquids and gases

Modular design: from mechanical indicator to 4…20 mA/HART®7, FF, Profibus-PA and totalizer

Any installation position: vertical, horizontal or in descending pipes

Flange: DN15…150 / ½…6"; also NPT, G, hygienic connections, etc.

The H250 M40 is the standard variable area (VA) flowmeter for the process and OEM industry. The VA meter combines mechanical flow measurement of liquids or gases with state-of-the-art communication capabilities. The device is modularly extendable. Additional electronic modules can be added or replaced at any time without process interruption. In this way, its functionality adapts to new requirements – from analogue flow measurement without auxiliary power to digital integration into a fieldbus system.

Simple, low-cost installation: able to measure and display without auxiliary power supply

Unique modularity and serviceability: Limit switches, 2-wire 4…20mA, totalizer with LCD and pulse output, fieldbus interfaces

NE 107 device and application diagnostics with CFM (Continuous Float Monitoring), e.g. for float blockade detection

Universal ex-concept: Explosion proof and intrinsically safe

Various stainless steel and alloy sensor materials

Optional stainless steel housing for corrosive atmospheres

Ingress protection IP66 and IP68 / NEMA4X and NEMA6, IP69K optional

Full scale value for liquids: 10…120,000 l/h / 5…32,000 GPH

Full scale value for gases: 0.7…2800 m3/h / 25…100,000 SCFH

Turndown ratio 10:1 (optional 100:1)

Maximum measuring error: ±1.6% (acc. to VDI/VDE 3513-2) or ±1.5% of full scale

Suitable for use in Safety Instrumented Systems with SIL 2, in redundant design (1oo2) also in SIL 3 applications (type A device)
