Fluid meter and power supply control method

Abstract

The invention provides a fluid meter and a power supply control method, and relates to the technical field of intelligent flow metering equipment. The fluid meter includes a metering mechanism and a fluid power generation device; the fluid power generation device includes an impeller, a transmission mechanism, a power generation body, and a clutch mechanism. The transmission mechanism includes a first transmission part and a second transmission part, and the first transmission part and the second transmission part can be clutched under the action of the clutch mechanism. The present invention can still flow the fluid to the user end through the pipeline when the front pressure of the pipeline is small. On the one hand, it meets the demand that the fluid power generation device can supply power to the intelligent flow metering equipment. On the other hand, it can be selected according to actual needs. Into the main body of the generator to meet the diverse needs of users.

Description

technical field [0001] The invention relates to the technical field of intelligent flow metering equipment, in particular to a fluid meter and a power supply control method. Background technique [0002] Flow measurement equipment such as water meters and gas meters are common items in daily life. Most of these flow measurement equipment are mechanical. The advantage of mechanical type is that it does not need to use power supply and can be used for a long time. With the advancement of science and technology, electronic smart flow metering equipment began to appear. The advantage of electronic smart flow metering equipment is that users can see the flow data intuitively. The disadvantage is that it needs to use electric energy. At present, general electronic flow metering equipment is powered by batteries or external power sources, and external power sources are often inconvenient, so most of them use batteries for power supply. When the battery power supply is low, it will...

Problems solved by technology

Although this form solves the problem of insufficient battery power affecting use, when water or gas is needed, the flow of fluid (water or gas, etc.) must drive the generator to rotate to flow out. When it is insufficient, it will make it difficult for the fluid to flow to the user end; and when the water pressure is appropriate, the generator will continue to supply power to the battery of the smart flow metering device, which will easily lead to overcharging of the battery and reduce the service life of the battery
