> Mass flow meters / controllers The mass flow sensor operates on a principle of heat transfer by sensing the temperature difference along a heated section of a capillary tube. Part of the total flow is forced through the capillary by means of a laminar flow element in the main stream generating a pressure difference. The design of the laminar flow device is such that flow conditions in both the capillary and laminar flow device are comparable, thereby resulting in proportional flow rates through the meter. The AT sensed by the upstream and downstream temperature sensors on the capillary...

MANIFOLD COMPONENTS The functional modules described on the previous page are mounted on a modular manifold assembly, consisting of support rails, base bodies, distribution and mixing chambers and adapter or blind plates. Support rails Configuration software tool Each FLOW-SMS system is supported by two mounting rails, which also provide panel mounting capability for the total system. There are support rail sets for 3 up to 9 channels available. Because of the infinite number of possible solutions, we recommend you to contact our nearest distributor to discuss your application. With the...
