Flow meter manufacturer from China（Kaifeng AFT Instrument Co.,ltd)

     The electromagnetic flowmeter uses the principle of Faraday's law of electromagnetic induction, that is, when a conductive object cuts a magnetic wire in a magnetic field, an induced electromotive force is generated in the conductor. Its induced electromotive force E is:      E=KBdV      The flow rate Q is: Q=3600*V*S      Where: K-meter factor       B-magnetic induction (T)       D-electrode spacing (m)      V-fluid average flow rate (m/s)      S-catheter cross-sectional area m2      When the flow rate is measured, the conductive liquid flows at a flow velocity V through a magnetic field perpendicular to the flow direction, and the flow of the conductive liquid induces a voltage proportional to the average flow velocity, and the induced voltage signal is detected by the electrode in direct contact with the liquid. For the same flow meter S...

     The correct selection of the ultrasonic flowmeter often plays an important role in the successful use of the flowmeter. Due to the complexity of the object to be measured and the variety of flowmeters, this makes the selection of the ultrasonic flowmeter somewhat difficult. No flow meter is perfect, all kinds of instruments have their own characteristics, the purpose of selection is to choose the most suitable flow meter key.       General ultrasonic flowmeter selection can be considered from the six aspects of measuring medium, flow rate, fluid characteristics, installation conditions, environmental conditions and economic factors, as follows:      1. Measuring medium: water, sea water, sewage, alcohol, oil, acid-base liquid, etc.;      2. Flow rate: accuracy, repeatability, linearity, measurement range, signal output characteristics, response time and pressure loss;      3. Fluid properties: temp...

Xu Zong, Xie Manager and Director Shang of our company are the main lecturers of the training.      In order to give us a deeper understanding of product knowledge, Xu introduced the types, characteristics, principles, technical parameters and uses of electromagnetic flowmeters, ultrasonic flowmeters , turbine flow streets and vortex flowmeters with vivid PPT. and take us to the workshop to observe the production process of the flowmeter. Mr. Xie Manager and Mr. Shang mainly explained the installation requirements of the flowmeter, and a...

Mass flow meters are now favored by users because they directly measure the mass flow of fluid in the pipeline, rather than measuring the volumetric flow and density of the fluid being measured, as calculated in the past, and then calculating it. In addition, its accuracy and stability are higher, the range ratio is larger, but its performance price ratio is too high. For manufacturers, this is a very profitable product, so the development, trial production and marketing of this product has been positive. Principle The principle of the Coriolis mass flowmeter is essentially to utilize the resonance characteristics of an elastomer: for the metal tube components of the fluid flow and the vibration without fluid flow (near the resonance region), the dynamic response characteristics are determined, and the resonance system is determined. The relationship between phase difference (time difference) and mass flow. The difference between the dynamic response characteristic of a metal tube elem...

     A turbine flow meter is a type of turbine that is supported by bearings at the center of the measuring pipe. When the fluid flows through the pipe, it impacts the turbine blades and drives the turbine to cause the turbine to rotate against the fluid resistance torque and the friction torque. Within a certain flow range, for a given fluid medium viscosity, the rotational angular velocity of the turbine is proportional to the fluid flow rate. Thus, the fluid flow rate can be obtained by the rotational angular velocity of the turbine, whereby the flow of fluid through the conduit is ultimately achieved by calculation.     Since the turbine flowmeter is sensitive to the conditions on site, the user should meet its ideal requirements with great satisfaction, so as to maintain the degree of factory instrumentation and obtain the desired measurement data. When the temperature pressure of the fluid medium differs greatly from the reference condition, the volume ch...
