Embodiment Construction

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0049] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relationship between various components under a certain posture (as shown in the accompanying drawings). The relative positional relationship, the movement situation, etc., if the specific posture changes, the directional indication also changes accordingly. ...

Abstract

The invention discloses a flow metering circuit and a flow metering device. The flow metering circuit comprises a HF probe, a RF receiving circuit and a micro-controller, wherein the HF probe emits aHF electromagnetic wave signal, a preset metal sheet emits the HF electromagnetic wave signal and then a reflective wave signal is obtained, the RF receiving circuit receives the reflective wave signal, then the reflective wave signal is processed so as to determine the flow direction of the flow body. Obviously, the flow direction of the flow body can be obtained accurately based on difference ofthe reflective wave signal, and then the technical problem that the flow direction of the flow body cannot be determined is solved.

Description

technical field [0001] The invention relates to the technical field of fluid measurement, in particular to a flow measurement circuit and a flow measurement device. Background technique [0002] A flowmeter is an instrument that measures the state of a fluid. Common flow meters often use the principle of electromagnetic induction to measure the flow state of the fluid according to the induced electromotive force. For example, parameters such as the flow rate of the water flow can be obtained. [0003] However, this kind of flowmeter is often unable to accurately judge the flow direction information of the water flow. [0004] Therefore, it can be considered that there is a technical problem that the fluid flow direction cannot be judged well. [0005] The above content is only used to assist the understanding of the technical solutions of the present invention, and does not mean that the above content is the prior art. SUMMARY OF THE INVENTION [0006] The main purpose ...
