Bürkert Mass Flow Controller (MFC)/mass Flowmeter (MFM) for Gases Type 8745

The mass flow controller (MFC)/mass flowmeter (MFM) type 8745 is suitable for controlling the mass flow of large gas quantities. Type 8745 can be configured as MFM or MFC according to demand. Optionally, up to four calibration curves can be stored in the device. The thermal inline sensor located directly in the main gas stream achieves very fast response times with minimal pressure loss. As the actuator, a Bürkert direct-acting proportional valve guarantees high response sensitivity. As an MFC, type 8745 is available in two variants: with electromagnetic proportional valve and with electromechanical proportional valve. In addition to an analogue and an industrial ethernet variant, a Modbus RTU variant is also available.
