A flow measurement in a conduit is combined with a thermal flow measurement made in a bypass channel to provide an increased range of flows over which an accurate measurement can be made. The thermal flow sensor in this combination is responsive only to a modulated component of the flow and thus provides a means of calibrating the zero of the composite instrument.
160 Thermal flow sensor having an electromagnetic actuator for a cyclic flow modulator US13781916 2013-03-01 US08650946B1 2014-02-18 Murray F Feller
A thermal flow sensor is responsive only to a modulated component of the flow. At zero flow the modulated component disappears, except for an artifact caused by motion of the modulator. This artifact is minimized by reducing the extent of modulator motion and by sampling the modulated signal at a quiescent part of the modulator's operating cycle. This results in a thermal flow sensor with a very stable zero.
