Bronkhorst High-Tech In-Flow mass flow meters

The Bronkhorst High-Tech In-Flow mass flow meters are modular instruments of rugged design according to IP65. They can be combined with integrated or close-coupled control valves to form compact digital mass flow controllers

Flow ranges can be measured within the ranges of 10-200 up to 50-5000 L/min. The ATEX approval for use of these instruments in Category 3, Zone 2 hazardous areas is pending.

Mass flow meters of the In-Flow series work on the basis of direct through-flow measurement (no bypass), following the constant temperature anemometer principle. The instruments contain no moving parts and have no obstructions to the flow path, which makes them suitable for low pressure drop applications and virtually insensitive to moisture or particulates.

The instruments have analog I/O signals and also an RS232 connection as a standard feature. In addition, there is the possibility of integrating an interface board with DeviceNet, Profibus-DP, Modbus or Flow-Bus protocol. The basic PC board features integrated PID control and various alarm and diagnostic functions.

Applications can be found in process control systems, and in food, chemical and petrochemical plants.
