The invention discloses a nonmagnetic flowmeter structure which comprises a fluid actuator, a transmission assembly and a photoelectric detection assembly. The fluid actuator is arranged in a fluid path, converts part of kinetic energy of fluid flowing along the pipeline into rotation energy, and outputs the rotation energy; the transmission assembly is in transmission connection with the fluid actuator, and receives and outputs the rotation energy; and the photoelectric detection assembly comprises a U-shaped mount for mounting photoelectric emitting and receiving ends and a shielding part in transmission connection with the transmission assembly, the shielding part is arranged in the U-shaped opening of the mount and is driven by the transmission assembly to block or conduct an optical path formed by the photoelectric emitting and receiving ends, and a detection structure signal is output. A traditional electromagnetic detection structure is changed into the photoelectric detection structure, and influence of magnetic field intensity change in the using environment of the water meter on a detection result can be avoided.
Description
technical field [0001] The invention relates to the field of water meters, more specifically, it relates to a non-magnetic flow meter structure and an intelligent water meter thereof. Background technique [0002] The water meter is a commonly used pipeline flow measurement device in production and life. Its main function is to measure the liquid flow through a certain set liquid pipeline. At present, the more commonly used smart water meters are mainly electromagnetic water meters. [0003] As far as the electromagnetic water meter is concerned, its structure is similar to that of the electromagnetic flowmeter. It is a speed meter designed and manufactured based on Faraday's electromagnetic induction principle to measure the volume flow of conductive media. Usually, the part of the electromagnetic water meter that is in contact with the medium (water) is a cylindrical straight tube, a pair of measuring electrodes are inlaid in the middle and distributed symmetrically, and ...
