Krohne Flowmeters H250 /M40 Oil Gas Water Chemical Flow Meter
Krohne flowmeters H250 /M40 oil gas water chemical flow meter
H250 with M10 indicator
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 M10 indicator:
- Integrated functionality - Graphic display for measured value and counter display - 2 limit switches (NAMUR or 3-wire transistor) - 2-wire analog output 4…20mA with HART - 12-digit flow counter with pulse output and reset input
- Pressure resistant, enclosed housing
- Operated using keys or magnetic stylus
- International approvals for use in hazardous areas (ATEX, FM, CSA, NEPSI) and nuclear power plants (N/NPT stamp)
- Sturdy stainless steel construction for high operating pressure up to 3000 bar and extreme process temperatures from -80°C to +200°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)
- Accuracy 1.6 % of measured value acc. VDI/VDE 3513-2 (qG=50%)
- Many different process connections - Flanges as per EN (DN15-DN100), ASME and JIS - Screw and clamp connections
- Special design for use in food and pharmaceutical industry with EHEDG approval
Further options
- Magnetic filters, if the medium contains particles which can be magnetically influenced
- Float damping for pulsating flows or low operating pressure (especially when measuring gases)
