Bürkert Type 8743 thermal mass flow controller

Bürkert has announced the expansion of its product range with the launch of the Type 8743 thermal mass flow controller (MFC) featuring a capillary sensor designed for aggressive gases and gas mixtures. The latest MFC is designed for gas flow measurement and control tasks in the food, chemical and petrochemical industries.

Capillary sensor technology is an indirect measuring method that ensures no direct contact with the gas, therefore providing high chemical resistance and suitability for aggressive gases and mixtures.

The Type 8743 offers IP20 ingress protection, handles flow rates of 0–100 l_n/min (nitrogen) and is equipped with both analog and digital interfaces.

The capillary sensor technology in the Type 8743 offers several advantages. The stainless steel capillary tube and sensor elements do not contact the gas, making these devices ideal for use with corrosive and reactive gases.

Laminar flow conditions in the sensor channel ensure a nearly linear relationship between the output signal and flow rate, simplifying gas conversion. Calibrated with nitrogen, the devices can use gas conversion factors, enabling flexible use with various gases and mixtures without the need for real gas calibration.
