Krohne's widely-used H250 variable area flowmeter is now available with a stainless steel M9 indicator housing, creating the option of an easy to clean, aseptic unit, suitable for use in hygiene-critical applications such as food, beverage and pharmaceutical manufacturing.
The meter can be tailored to give accurate and reliable results across a broad range of process applications. Its modular construction enables simple plug-in upgrading of optional features such as limit switches, flow totalisers, high temperature adapters and 4 to 20 mA transmitter. To reduce process interruption and downtime, all options can be added at any time without having to re-calibrate the instrument.
The M9 converter can also incorporate an intrinsically safe (Eex i), 2-wire design 4-20 mA HART transmitter, which allows completely safe operation of the H250 variable area meter in hazardous environments. Profibus PA communication is also available for integration into more sophisticated control systems.
All wetted parts available in either stainless steel, Hastelloy or PTFE/ceramic, making the instrument suitable for process liquids or gases at temperatures up to 300°C, pressures up to 4 MPa and flow rates from 2,5 to 100 kl/h.
