Embodiment Construction
[0016] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings and examples. The following examples are only used to illustrate the technical solutions of the present invention more clearly, but not to limit the protection scope of the present invention.
[0017] The liquid sensor of the present invention can be used to measure the pressure value and flow value of the liquid, and can be applied to various liquids, not limited to water and petroleum. The following will use water as an example for description, but it is not used to limit the scope of application of the present invention.
[0018] like figure 1 As shown, it is a schematic structural diagram of a liquid sensor according to an embodiment of the present invention. The liquid sensor includes a front cover 1, a connecting body 5, a rear end cover 9, a pressure core 7, a rotor 4, a Hall element 10, a magnet 3 and Processor 11, the front end cove...

The invention discloses a composite flow pressure sensor, which includes a front cover, a pressure core, a rotor, a Hall element, a magnet and a processor. A cavity for placing the rotor is formed in the front cover, and the magnet is arranged on the On the rotor, it rotates together with the rotor; the Hall element is arranged on the front end cover, and is used to obtain pulse signals according to the rotating magnet; the cavity in the front end cover communicates with the pressure The core is connected, and the processor is connected with the Hall element and the pressure core, and is used to receive the pulse signal of the Hall element and the pressure signal of the pressure core, and output the pressure of the liquid according to the pulse signal and the pressure signal. Pressure value or / and liquid flow value. The invention combines the traditional water pressure sensor and the water flow sensor into one, and has all the functions of the water pressure sensor and the water flow sensor at the same time.
Description
technical field [0001] The invention belongs to the technical field of detection instruments, and relates to a liquid sensor, in particular to a sensor capable of simultaneously detecting liquid pressure and flow. Background technique [0002] In the existing technology, the pressure and flow detection of liquid are two separate products. The water pressure sensor is used in the water flow monitoring system to detect the water pressure in the water inlet and outlet of the irrigation valve and the pipeline. Water flow sensors are used in water flow monitoring systems to detect water inflow and outflow from irrigation valves. [0003] The above two devices are the most commonly used in automatic water-saving irrigation systems, and their data are also two important parameters required by the water supply system. As two independent detection devices, it will inevitably bring inconvenience to users in operation, maintenance and installation, and at the same time, it will bring...
