Electronic flowmeter type flowmeter

Abstract

The invention discloses an electronic flowmeter type flowmeter. The flowmeter comprises a flowmeter body, a water outlet pipe is fixed at the front end of the flowmeter body, and first transverse water guide pipes are symmetrically arranged at the left end and the right end of the water outlet pipe. Longitudinal water guide pipes are symmetrically arranged at the left end and the right end of thefirst transverse water guide pipe, the ends, away from the water outlet pipe, of the first transverse water guide pipes are fixedly connected with longitudinal water guide pipes, and cleaning mechanisms are fixed to the upper ends of the longitudinal water guide pipes. Material receiving mechanisms are fixed to the lower ends of the longitudinal water guide pipes, a second transverse water guide pipe is fixed between the longitudinal water guide pipes, a water inlet main pipe is fixed to the second transverse water guide pipe, and a water outlet pipe and a water outlet pipe are arranged at theleft end and the right end of the flow meter body in a left-right manner. According to the electronic flowmeter type flowmeter, the two sets of filter screens are arranged and can be alternately used, so that the working efficiency is guaranteed; the filter screens are obliquely arranged, and the cleaning mechanism and the material receiving mechanism are arranged, so that the filtered impuritiesare conveniently collected, and the filter screens are conveniently cleaned.

Description

technical field [0001] The invention relates to the field of metering equipment, in particular to an electronic flowmeter type flowmeter. Background technique [0002] The flow meter is composed of a flange, a housing, an inlet rectifier, a metering chamber, a flow converter and an outlet rectifier. When the fluid passes through the gap between the vane and the pipe, the force generated by the pressure difference between the front and back of the vane pushes the vane and makes the rotor rotate. . While the rotor rotates, the blades periodically cut the field lines generated by the electromagnets, changing the magnetic flux through the coils. According to the principle of electromagnetic induction, an electric pulse signal will be induced in the coil. After the signal is amplified, it is sent to the display instrument. Within a certain flow range, the number of electrical pulse signals is proportional to the flow. The flow converter processes and calculates the electrical...

Problems solved by technology

[0003] In order to avoid the impact of impurities in the water on the rotation of the screw rotor in the existing spiral self-flowmeter, a filter is usually installed in the fluid input pipe of the flowmeter to filter the impurities in the fluid. The filter needs to be cleaned regularly. When the net is cleaned, the flowmeter needs to be removed, and then the filter net is taken out for cleaning, which is troublesome and affects the work of the flowmeter. Therefore, we propose an electronic flowmeter type flowmeter
