    50mm Acid Electromagnetic Flow Meter High Accurancy for City Administration


    Sensor dimension


    The flange connection is adopted as the sensor’s fixation. First, the connection pipes length of
    base could be calculated according to pipe diameter, and then holes could be opened in the pipe,
    after that the base will be welded on holes in the pipes; during welding the correct direction of
    base flange screw hole and insert depth should be paid attention to make the sensor pole vertical to
    flow direction. The base connection pipe is not allowed to be exceeding the inner surface of
    measurement pipe to keep its inner surface of the pipe smooth. The exact size and material
    specification are illustrated as the following drawing.


    Adapter structure


    The instrument is a kind of intelligent system. The flow signal is magnified before the calculation
    by signal-chip computer, and then the flow and accumulation value are indicated as well the
    output of impulse and analog item, which is used for liquid flow calculation and control. The
    small-type one-unit optimization design is adopted in the adapter, which is installed inside
    aluminum cover with safety class lp65.


    Sensor structure


    The sensor is composed of measurement detector, installation flange and wire box (separate type)
    Adapter
    Flange
    Base
    and so on. The sensor outline is in cylinder shape with installation flange, inside which the
    excitation winding used for exciting, magnet-conductive winding and two electrodes of
    magnet-conductive core, contacting liquid, are installed.


    The design of sensor installation location


    The sensors could be erected at any position, however, the method illustrated as the drawing
    below is recommended to make sure that the electrode could be in the liquid all the times.

    The sensors should be installed on the pipes inside which there are liquid all along, and it is
    always risky to bear whirlpool if the pipe is half-full, as well as to be installed behind valve, elbow,
    tee-joint as they are also the stem of whirlpool. In this case, the length of straight pipe before
    sensors should be at least > 10D and straight pipe > 5D after sensor, by which the whirlpool
    could be avoided and measurement accuracy improved. If the accuracy is required at ±0.5%, the
    length of straight pipe before sensors should be at least > 30D and straight pipe > 10D after
    sensor.


    lining materials(Only for reference)

    Lining materialMain PerformanceApplied Scope
    PTFE
    1. Have the most stable chemical properties in plastics, and resist boiling hydrochlor and sulfuric acid, nitric acid aqua regia, strong alkali, and all kinds of organic solvents, but can not resist the corrosion of chlorine trifluoride, liquid fluorine, liquid oxygen and ozone.
    2. Low abrasion resistance

    3.Low negative pressure resistance

    1. -25℃-140℃

    2. Strong corrosion medium, like strong acid and alkali.

    3.Healthcare medium

    Hard Rubber
    1. Good resistance to room temperature, hydrochloric acid, acetic acid, oxalic acid, ammonia, phosphoric acid and 50% sulfuric acid, sodium hydroxide, potassium hydroxide
    2. Avoid strong oxidants

    1.<80℃

    2.General acid, alkali, salt solution

    PFA
    1. can be used for most corrosive medium like acids, alkalis, and strong oxidant.
    2. 2.high material strength, resistance to aging, better than PTFE,EFP in high temperature
    3. Injection molding for higher negative pressure

    1.40-180℃

    1. strong corrosion medium, like strong acid and alkali
    2. Healthcare medium
