TBW vortex flowmeter

    Low compressed air
    Low saturated steam
    Low superheat steam
    Low general liquid o
    Simple structure, no sports wear parts, easy to install and maintain.
    High accuracy, high reliability, do not need the scene debugging.
    The pressure loss is small, span a wide range.
    Piezoelectric stress testing body installed on the vortex behind, to reduce the effects of the impurity in the medium.
    Detecting element is not in contact with the measured medium, especially suitable for flow measurement in bad environment.
    Can live shows or long-distance traffic signals, and computer networking, centralized management.
    Amplified board adopts unique design, gas, liquid.
    Flexible installation, can be installed in vertical, horizontal or different inclined Angle.
    The interference elimination circuit and vibration sensing head, has a good resistance to vibration performance.

  TBW type vortex flowmeter is d on the principle of the karman vortex street research and production, mainly used in industrial pipeline medium fluid flow measurement, such as gas, liquid and vapor, and other media.Is characterized by small pressure loss, wide range, high precision, working condition of the measurement volume flow is almost not affected by the fluid density, the influence of the parameters such as pressure, temperature, viscosity.No moving mechanical parts, so high reliability, small amount of maintenance.Vortex street flowmeter using piezoelectric stress sensor, high reliability, cooperate the measures such as isolation, shielding, filtering, overcome similar products such problems as poor vibration resistance, small signal disorders;Can be in - 20 ℃ ~ + 250 ℃ temperature range.There are analog standard signal and digital pulse signal output, easy, with digital systems, such as computers, is a kind of more advanced, the ideal measuring instrument.
