The new In-Flow mass flowmeters (photo) are modular instruments of rugged design according to IP 65 (dust- and waterproof). They can be combined with integrated or closed-coupled control valves to form compact digital Mass Flow controllers, delivering measured and controlled flow ranges of 10–200 mL/min up to 50–5,000 mL/min. The ATEX approval for use of these instruments in Category 3, Zone 2 hazardous areas is pending. The devices have analog I/O signals and an RS 232 connection as standard, with the possibility of integrating an interface board with DeviceNet, Profibus-DP, Modbus or FLOW-BUS protocol. — Bronkhorst High-Tech B.V., Ruurlo, the Netherlands
