A filter flow meter

Abstract

The invention discloses a filtering-type flowmeter which comprises a flowmeter body. The flowmeter body comprises a measuring barrel for measuring volume flow and an indicator fixedly connected with the measuring barrel and used for displaying measuring data of the measuring barrel, a water incoming pipe and a water outgoing pipe are arranged on the measuring barrel, an inlet end of the water incoming pipe is connected with a filtering pipe, and a filter is arranged at one end, away from the water incoming pipe, in the filtering pipe and comprises a shell and a core rod; the shell comprises a clamping connection portion and a rotating handle portion, the peripheral surface of the clamping connection portion is coated with an elastic rubber layer, outer diameter of the rotating handle portion is greater than that of the clamping connection portion, one end of the core rod is fixed inside the shell through a connection member, axis of the core rod is coincident with that of the shell, a plurality of magnetic rods are fixedly mounted on the core rod and spirally arranged from bottom to top along the axis of the core rod, a filtering barrel is arranged in an inner cavity of one end, close to the water incoming pipe, of the filtering pipe, and at least two lateral-layer filtering nets are arranged in the filtering barrel. Measuring accuracy is improved, and service life of the flowmeter is prolonged.

Description

technical field [0001] The invention relates to the technical field of instruments and instruments, in particular to a filter type flowmeter. Background technique [0002] The flow meter is composed of a water level flow rate sensor (probe), a host computer (terminal) and a communication cable. It is an instrument used to measure the volume flow of various sewage in pipelines and channels. [0003] With the development of industrial production, various flow meters are widely used in the field of industrial control. However, due to the complexity of industrial production, many impurities are often mixed in the fluid, which has a great impact on the measurement of the flow meter system and greatly restricts the stability of the flow meter system. Performance and reliability, serious damage to the flow meter system. Contents of the invention [0004] Based on the technical problems in the above background technology, the present invention proposes a filter flowmeter to impro...
