摘要: A mass flow meter employs discrete chip-type temperature sensors to sense a fluid flow rate. The sensor can be a semiconductor chip such as SiC or silicon, or thin film tungsten on an AlN substrate. The sensors can be distributed symmetrically with respect to the conduit through which the fluid flows, and can be connected in a four-sensor bridge circuit for accurate flow rate monitoring. An output from the mass flow meter can be used to control the fluid flow.

摘要: Methods and apparatus for measuring the dielectric relaxation properties of a sample are disclosed. Methods are disclosed for amplifying or controlling the dielectric relaxation properties of a sample by adding particles, such as functionally coated particles. In certain methods, the particles amplify or control the dielectric relaxation properties of the sample by interacting with counter ions in the sample. In some embodiments, the methods use a dielectric relaxation spectroscopy apparatus with remote electrodes.
