Description

Technical Field

[0001] The utility model relates to the technical field of volute water inlet flow measurement tools, in particular to a volute water inlet flow electromagnetic measurement device. Background Art

[0002] Volute is the abbreviation of volute water diversion chamber. The cross-section of the volute gradually decreases. In order to ensure uniform water supply to the water guide mechanism, the volute can form a necessary ring volume in front of the water guide mechanism to reduce the working intensity of the water guide mechanism. The volute is provided with an inlet pipe and an outlet pipe, so that the fluid can enter and be discharged along the inlet pipe.

[0003] In order to measure the water flow rate at the water inlet pipe on the volute, a corresponding water flow electromagnetic measuring device is usually installed at the water inlet pipe. Common water flow electromagnetic measuring devices include electromagnetic flowmeters, etc. The electromagnetic flowmeter uses the principle of electromagnetic induction to measure the flow rate of conductive fluid based on the induced electromotive force when the conductive fluid passes through an external magnetic field.

[0004] The water inlet pipe on the volute on the market is generally only equipped with one electromagnetic flowmeter. However, when the electromagnetic flowmeter is subsequently repaired or replaced after being damaged, the entire pipeline needs to be stopped for replacement or repair. The whole machine shutdown will delay the progress and bring inconvenience to the user. In view of this, we propose an electromagnetic measuring device for the water inlet flow of the volute.
