• Nominal flow r anges from 0.010 lN/min to 80 lN/min High accur acy and repeatability V ery fast settling times Optional: Fieldbus int erface The mass flow controller (MFC) Type 8711 is suited for regulating the mass flow of gases over a big flow range. The thermal MEMS sensor is located directly in the gas stream and therefore reaches very fast response times. A direct-acting proportional valve from Bürkert guarantees a high sensitivity. The integrated PI controller ensures outstanding control characteristics of the MFC. Type 8711 can optionally be calibrated for two different gases; the user can switch between these two gases. As electrical interfaces both, analog standard signals and fieldbuses are available. The mass flow controller type 8711 fits for various applications, like e.g. burner controls, heat treatment, material coatings, bio reactors, fuel cell technology or test benches. Product variants described in the data sheet may differ from the product presentation and description. Type descriptionCan be combined with Type 8711 © Christian Bürkert GmbH & Co.

Measuring principle The mass flow sensor operates according to a thermal principle which has the advantage of providing the mass flow which is inde- pendent on pressure and temperature. A small part of the total gas stream is diverted into a small, specifically designed bypassing channel which ensures laminar flow conditions. The sensor element is a chip immersed into the wall of this flow channel. The chip, produced in MEMS technology, contains a heating resistor and two temperature sensors (thermopiles) which are arranged symmetrically upstream and downstream of the heater. The differential voltage of the thermopiles is a measure of the mass flow rate passing the flow sensor. The calibration procedure effectuates a unique assignment of the sensor signal to the total flow rate through the device. 5.2. Flow char acteristic Nominal flow range of typical gases Note: Q(Gas) = f x Q(N2) When using the gas fact ors, measurement errors may occur that are outside the data sheet specification. For applications requiring high accuracy, calibration under field conditions is recommended. F urthermore, the media compatibility of the sealing materials of the MFM should be checked before use with another gas. Gas Min. QNom Max.

Recommendation r egarding product selection Note: Please use the „Product Enquiry Form“ at the end of this document for unit design details and send us a copy of the enquiry with information about the application. For the proper choice of the actuator orifice within the MFC, not only the required maximum flow rate QNom, but also the pressure val- ues directly before and after the MFC (p1, p2) at this flow rate QNom should be known. In general, these pressures are not the same as the overall inlet and outlet pressures of the whole plant, because usually there are additional flow resistors (tubing, additional shut-off valves, nozzles etc.) present both before and after the controller. Please use the „Product Enquiry Form“ at the end of this document to indicate the pressures directly before and after the MFC. If these should be unknown or not accessible to a measurement, estimates are to be made by taking into account the approximate pressure drops over the flow resistors before and after the MFC, respectively, at a flow rate of Q Nom. In addition, please quote the maximum inlet pressure p1 max to be encountered. This data is needed to make sure the actuator is able to provide a close-tight function within all the specified modes of operation. 6.3.
