Thiết bị đo lưu lượng Bronkhorst In-Flow F-111BI
Đồng hồ đo lưu lượng Bronkhorst IN-FLOW F-111BI Industrial Style Thermal Mass Flow Meter for Gases có độ chính xác cao, chức năng Multi Fluid / Multi Range tùy chọn, hầu như không phụ thuộc vào áp suất và nhiệt độ, thiết kế nhỏ gọn chắc chắn, chống chịu thời tiết (IP65, chống bụi và chống thấm nước).
Bronkhorst® model F-111BI Mass Flow Meters (MFMs) are suited for precise measurement of flow ranges between 0,16…8 mln/min and 0,16…25 ln/min with pressure rating between vacuum and 100 bar. The MFM consists of a thermal 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 IN-FLOW model is of rugged design (IP65) for use in industrial environments or even Zone 2 hazardous areas, with optional ATEX Cat. 3 or FM Class I, Div. 2 approval.

IN-FLOW series are equipped with a digital pc-board, offering high accuracy, excellent temperature stability and fast response. The main digital pc-board contains all of the general functions needed for measurement and control. 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 CANopen®, DeviceNet™, EtherCAT®, PROFIBUS DP, PROFINET, Modbus RTU, ASCII or TCP/IP, EtherNet/IP, POWERLINK or FLOW-BUS protocols. The IN-FLOW model features optional Multi Gas / Multi Range functionality, providing (OEM-) customers with optimal flexibility and process efficiency.
