Abstract

The invention discloses a combined type flow and pressure sensor. The combined type flow and pressure sensor comprises a front end cover, a pressure core, a rotor, a Hall element, a magnet and a processor, wherein an accommodating cavity for accommodating the rotor is formed in the front end cover, the magnet is arranged on the rotor and rotates together with the rotor, the Hall element is arranged on the front end cover and used for acquiring pulse signals according to the rotating magnet, the cavity in the front end cover is connected with the pressure core through a liquid channel, and the processor is connected with the Hall element and the pressure core and used for receiving the pulse signals of the Hall element and pressure signals of the pressure core and outputting the pressure value or / and flow value of liquid according to the pulse signals and the pressure signals. According to the combined type flow and pressure sensor, a traditional water pressure sensor and a water flow sensor are combined, and all the functions of the water pressure sensor and the water flow sensor are realized.

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...
