A multifunctional water meter

Abstract

The invention discloses a multifunctional water meter, which is characterized in that it comprises a casing, a large flow metering chamber, a hardware chamber and a small and micro flow metering chamber, the casing is provided with a water pipe inlet and a water pipe outlet, and the water pipe The connection outlet is connected with the small and micro flow metering chamber, and the large flow metering chamber is connected with the small and micro flow metering chamber through an electric control valve. A generator and an impeller driving the generator to rotate are arranged in the large flow metering chamber. A large rotor flowmeter and a small rotor flowmeter are arranged in the small and micro flow metering cavity, a correction shaft is arranged in the large rotor flowmeter, the large rotor in the large rotor flowmeter is set on the correction shaft, and the The aperture of the large rotor flowmeter gradually decreases from top to bottom, and the aperture of the small rotor flowmeter gradually increases from top to bottom, and a signal processing module is arranged in the hardware room. The invention has the advantages of simple structure and convenient manufacture, adopts large rotor flowmeter and small rotor flowmeter to measure small and micro flows, and has high measurement accuracy.

Description

technical field [0001] The invention relates to a water meter, in particular to a multifunctional meter for collecting pH value, turbidity, chlorine concentration, pressure and flow. Background technique [0002] The existing tap water meter has the following disadvantages: [0003] 1. It can only measure the water consumption at the time of large flow, and cannot measure the small and micro flow; [0004] 2. The mechanical transmission structure is used for measurement, and the measurement accuracy is low; [0005] 3. Complex structure, difficult manufacturing and high production cost; [0006] 4. It cannot collect and process multiple parameters at the same time. [0007] Therefore, a new technical solution is needed to solve the above technical problems. Contents of the invention [0008] In order to overcome the above-mentioned defects, the present invention provides a multi-functional water meter, which has a simple structure, is convenient to manufacture, and is ...
