Embodiment Construction

[0024] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0025] Such as figure 1 As shown, a non-magnetic sensor flowmeter, including impeller, acquisition module, main control module,

[0026] The output end of the impeller is connected to the input end of the acquisition module, and the output end of the acquisition module is connected to the input end of the main control module.

[0027] Such as figure 2 As shown, in a specific embodiment, half of the surface area of ​​the impeller is coated with damping metal, such as copper. The acquisition module includes three LC resonant circuits composed of inductors and capacitors. The induction coils 1, 2, and 3 in the resonant circuits are evenly distributed above the impeller 5, keeping a certain distance from the impeller, and not directly in contact with the impeller. .

[0028] The main control module includ...

Abstract

The invention discloses a flow meter without magnetic sensors. The flow meter comprises an impeller, an acquisition module and a main control module, the output end of the impeller is connected with the input end of the acquisition module, and the output end of the acquisition module is connected with the input end of the main control module. The flow rate and flow speed changes of water flow canbe effectively detected through the acquisition module, and the magnetic sensors do not need to be adopted, so that the defects that flow meters with the magnetic sensors are high in power consumptionand inaccurate in measurement precision are overcome. Dismounting and monitoring can be achieved through a state decoding unit, the main control module can automatically work in a set sequence, and the power consumption is obviously reduced. The flow meter is simple in structure, low in cost, high in measurement precision, low in power consumption and capable of being widely applied to the fieldof instruments and meters.

Description

technical field [0001] The invention relates to the field of instruments and meters, in particular to a flowmeter without a magnetic sensor. Background technique [0002] The traditional flowmeter solution mainly uses magnetic sensors such as Wiegand sensors and Hall sensors for flow detection. The system consumes high power, and the built-in battery of the flowmeter has a short working time. The impeller needs to be equipped with a permanent magnet, and metal impurities in the water will be adsorbed on the impeller. , affecting the measurement accuracy of the flowmeter. [0003] At the same time, traditional flowmeters cannot achieve dismantling monitoring. [0004] In summary, it is necessary to provide a flowmeter without a magnetic sensor to solve the above technical problems. Contents of the invention [0005] In order to solve the above technical problems, the object of the present invention is to provide a flow meter that does not need to use a magnetic sensor, ha...
