1. What are the types of rotary flow meters? Rotary flow meters are mainly divided into two categories: glass rotors and metal tube floats. 1. Glass rotor flow meters are usually of the local indication type or with switch signal output, which has strong corrosion resistance and can be used to detect the flow of acids (except hydrofluoric acid), alkalis, oxidants, and other corrosive gases or liquids. They are commonly used in industries such as chemical engineering, Shennian Qi Pharmaceutical, papermaking, and sewage treatment. However, due to the fragility of glass material, it is less commonly used at critical control points. Metal tube float flow meters are usually made in the form of flow transmitters, which can be divided into electric remote transmission and on-site pointer display types according to different converters. It mainly consists of three parts: indicators (such as intelligent indicators, local indicators), floats, and conical measuring chambers. The introduction of the new generation metal tube float flowmeter into the computing system further enhances its usability and advantages, with features such as high accuracy, good repeatability, and small maintenance range.

Working principle of HR-F series intelligent metal tube float flowmeter

1. Structure: The HR-F series metal tube sales source touch float flowmeter mainly consists of two parts: measuring tube and HR-F indicator.. The measuring tube includes conical tube or orifice plate, guide, stopper, float and other components, while the indicator includes magnetic follow-up system, pointer, dial, circuit and other components.

、 The working principle is that the measured medium flows from bottom to top through the measuring tube, generating a differential pressure at the upper and lower ends of the float to form an upward force. When the upward force on the float is greater than the weight of the float immersed in the fluid, the float rises, and the annular gap area increases accordingly. The fluid flow velocity at the annular gap rapidly decreases, and the differential pressure between the upper and lower ends of the float decreases. The upward force acting on the float decreases until the upward force is balanced with the weight of the float immersed in the fluid. The float is stable in a certain position, and the height of the float position immediately corresponds to the flow rate of the measured medium. The float is equipped with magnetic steel, and when the float moves up and down with the medium, the magnetic field changes with the movement of the float. For the in-situ type, the following magnetic steel in the in-situ indicator is coupled with the magnetic steel inside the float to rotate, while driving the pointer to indicate the current flow rate through the dial. (As shown in Figure 1) For the intelligent type, rotation occurs due to the coupling between the follower magnet in the intelligent indicator and the magnet inside the float. Simultaneously driving the sensing magnet and pointer, the magnetic field changes are converted into electrical signals through a magnetic sensor. After A/D conversion, digital filtering, temperature compensation, microprocessor processing, D/A output, and LCD display, the instantaneous flow rate and cumulative flow rate are displayed. (As shown in Figure 2)
