Abstract:
    A blocking-flow flow sensor is disclosed that comprises the casing of the sensor which is characterized in that a T-type body core is mounted in the casing, the board is located on the upper side of the body core, two detectors that are face to face is mounted on the lower side of the body core, the detectors connects with the board; a elastomer assembly is set between the two detectors, the elastomer is decussate texture which has two symmetrical resilient arm and oscillating arm that is fixed to the body core by the U-shaped mount; the magnetic conductor which is mounted on the upper end of the oscillating arm is corresponding to the detector, a target board is located at the lower end of the oscillating arm and is corresponding to the position of ejector nozzle in porch of the casing. The invention is characterized in small volume, light weight, low power consumption, low pressure drop, corrosion prevention, high accuracy and no mechanical abrasion; it is suitable for applying in the liquid delivery pipes.
