    摘要: A flow velocity measuring device is able to conduct a fluid to a sensor element after removal of dust and dirt contained in the fluid to accurately measure the flow velocity of the fluid even when the fluid is low in flow velocity and the device is mounted in any direction. A flow passage is formed by internal spaces, which have curved wall surfaces, introduction passages connected to the internal spaces at one ends of the wall surfaces tangentially to the wall surfaces, discharge passages connected to the internal spaces at the other ends of the wall surfaces tangentially to the wall surfaces, and branch discharge passages connected to the internal spaces at substantially right angle to a direction, in which the wall surfaces are curved, and a sensor element is arranged in the branch passage or a flow passage connected to the branch passage.

    摘要: A flow measurement device according to the present invention includes a main flow channel through which fluid flows, and a secondary flow channel unit where the fluid is diverted from the main flow channel, supplied to a flow amount detection element and thereafter returned to the main flow channel. The secondary flow channel unit includes a diversion flow channel through which the fluid is diverted from the main flow channel and returned to the main channel without the fluid being supplied to the flow amount detection element, and a detection channel in which the fluid is diverted from the diversion flow channel and provided to the flow amount detection element. The diversion flow channel includes a smooth flow part in which the fluid flows smoothly between the two ends connecting to the main flow channel, and a first chamber and a second chamber which, adjacent to the smooth flow part, are divided by a partition provided so as to obstruct flow of the fluid. The two ends of the detection channel are connected to the first chamber and the second chamber.
