Abstract
A flow sensing module with a bypass channel is provided. The flow sensing module may include a body portion and a flow sensor. The body portion may include a main fluid inlet, a main fluid outlet, a main fluid channel extending between the main fluid inlet and the main fluid outlet, a bypass fluid inlet and a bypass fluid outlet each configured to be in communication with the main fluid channel, and a bypass fluid channel extending between the bypass fluid inlet and the bypass fluid outlet. The flow sensor may be disposed in the bypass fluid channel to sense a flow rate of a fluid in the bypass channel. No pressure drop element is disposed in the main fluid channel, so the main fluid channel may have a pressure loss of a very small value. Moreover, linearity and sensitivity of the flow sensing module may also be improved.
