TBD Electromagnetic flowmeter

    The drinking water, sewage
    The water treatment industry
    One or two - Thermal Network
    The effect of the change of fluid density, viscosity, temperature, pressure, and electrical conductivity is measured.
    No flow parts, no pressure loss, straight pipe section requirements is lower, the measurement of the slurry has a unique adaptability.
    Series nominal diameter DN6~DN3000, sensor lining and electrode material have a variety of options.
    The converter uses novel excitation mode, low power consumption, zero point stability, high accuracy, and traffic range can reach 1500:1
    In the field can be d on the actual need to modify the scale online.
    High definition backlight LCD display, the entire Chinese menu operation, easy to understand.
    Self diagnostic and self diagnostic function
    The insertion electromagnetic flowmeter, simple installation, can not stop, the pressure opening, has the absolute price advantage and installation.

  TBD series electromagnetic flowmeter is d on Faraday electromagnetic induction principle, with the sounding pipe axis and the magnetic field lines in the vertical tube wall installed on a pair of detecting electrodes, when conducting liquid along the measuring tube axis movement, conductive liquid cutting lines of magnetic force induced electric potential, the induction electric potential by two detection electrodes detection, numerical directly proportional size and velocity.By measurement of body must be the electrical conductivity of a liquid or slurry, the conductivity should be less than 50 mu s/cm can be used with double core double equipotential shielding shielding wire or high frequency converter, the current body should not contain more ferromagnetic substance or bubbles, should according to the characteristics of the current body to choose the appropriate pressure levels, lining materials, electrode materials and instrument structure.Using 16-bit ded microcontroller processor, operation speed, high precision, low frequency rectangular wave excitation, and the excitation frequency programmable Settings, improve the stability of the flow measurement.Is widely used in chemical fiber, food, papermaking, sugar-making, mining and llurgy, water conservancy, pharmaceutical and other industrial fields.
