Thông tin sản phẩm

Bronkhorst® model D-6320 Mass Flow Meters (MFMs) are suited for precise measurement of flow ranges between 0,05…1 ln/min and 0,35…7 ln/min at operating pressures between vacuum and 10 bar (Aluminium) or 20 bar (Stainless Steel). The MFM consists of a proven inline thermal (CTA) mass flow sensor and a microprocessor based pc-board with signal and fieldbus conversion and a PID controller for optional mass flow control by means of a separately mounted control valve. The instument is IP65 complient and can optionally be equipped with a modern, multi-functional and multi-colour display, with operator buttons on the instrument.

The digital MASS-STREAM™ series is characterized by a high degree of signal integrity and, as an option, up to 8 calibration curves of different gases and process conditions can be memorized in the instrument. In addition to the standard RS232 output the instruments also offer analog I/O. As an option, an on-board interface can be mounted to provide DeviceNet™, PROFIBUS DP, Modbus-RTU or FLOW-BUS protocols.

Proven direct inline CTA sensor (no bypass)
Compact, rugged design (IP65, dust and waterproof)
Very low pressure drop
Less sensitivity to humidity or dirt

Optional with integrated TFT display
