    Magnetic Flow Meter Installation

    Usually, the magnetic flow sensor housing protection is extremely IP67 and has the following requirements for the installation site. Let's follow ATO to learn more about it.

    What is Flow Meter Used for?

    Flow meter is an instrument used to measure the flow of fluids in pipelines or open channels. It measures various media, including gas, liquid, slurry, and steam. In the field of automation, flowmeters play an important role as front-end instruments. Each product of flow meter not only has its specific applicability, but also has its limitations. According to the measurement object, there are two categories of closed pipes and open channels; according to the purpose of measurement, it can be divided into total measurement and flow measurement. The instrument are called total meter and flow meter respectively.

    What is Flow Meter and Its Types?

    A flow meter is a professional automatic measuring instrument. Its main function is to measure the flow of fluids. The measurement medium includes liquid, gas, steam, mixed slurry, solid dust, etc. In the field of industrial automation, flow meters and sensors are called the eyes of the automation system. The result of flow meter measurement is transmitted to the upper computer system, which will integrate and analyze the data and other work, and then apply the preset scheme to the upstream and downstream control systems to play the purpose of intelligent automatic control.

    Flow Meter Price List

    A flow meter is an instrument used to measure the volume or mass of a gas or liquid. offers you various flow meters including magnetic flow meter, vortex flow meter, turbine flow meter and portable ultrasonic flow meter, to suit your different applications. Then, how can you choose an appropriate flow meter? It can be considered from five aspects: flow meter performance, fluid characteristics, installation conditions, environmental conditions and economic factors.

    How to Select a Right Magnetic Flow Meter?

    Nowadays, the magnetic flow meter (electromagnetic flow meter) has been widely applied to measuring of industrial sewage or wastewater. With a high precision and a long service life, the magnetic flow meter is the top choice for the environmental measuring industry. To choose the correct magnetic flow meter can five fuller play to the magnetic flow meter for specific purposes. Generally, the selection of the magnetic flow meter is based on the following factors including chemical attributes of the fluid medium, pipeline diameter, flow range, liner material, electrode material and output signal.

    How Magnetic Flow Meter Works?

    A magnetic flow meter, mag meter, or electromagnetic flow meter is a kind of instrument which measures the volume flow rate of the conductive fluid based on the principle of Faraday's Law of Electromagnetic Induction. With a large measurable flow range, the ratio of the maximum flow rate to the minimum flow rate maintains above 20:1. The mag flow meter is suitable for wide range of industrial pipe diameter, and the maximum can reach up to 3m. The output signal and the measured flow are linear, and the magnetic flow meter has high measurement precision. It can effectively measure the flow rate of fluids with a conductivity more than 5μs/cm, such as acid solution, alkaline solution, saline solution, water, sewage, corrosive liquid, mud, ore pulp, and paper pulp. Nevertheless, the electromagnetic flow meter cannot be used to measure the flow of gases, steam and purified water.

    What Affects Magnetic Flow Meter Measurement Accuracy?

    Magnetic flowmeter is a widely used instrument that plays an important role in the measurement of waste water and sewage. However, due to mistakes in model selection, installation and use, it may eventually affect the measurement accuracy of magnetic flow meter, causing deviation of measurement data and even damaging to the flowmeter. Now ATO will guide you to analyze why measurement errors in magnetic flow meter happen and how to troubleshoot these problems.

    1. The liquid to be tested contains bubble.
    2. The liquid to be measured is non-full in pipe.
    3. Short circuit effect of conductive sediments
    4. The liquid generates crystallization.
    5. Liquid conductivity exceeds allowable range.
    6. Spatial electromagnetic disturbance
    7. Unsymmetrical flow of the fluid to be measured
    8. Vibration of the installation site affects the accuracy of magnetic flowmeter.
