Smart liquid turbine flowmeter Introduction: turbine flowmeter is measured by the sensor according to the liquid, the impeller is rotated by means of kinetic energy of the liquid within the sensor. At this point, the impeller blades so that the magnetic resistance detection means changes periodically, so that it ends in the detection coil induces an electrical pulse signal frequency proportional to flow, amplified by an amplifier remote output. The smart liquid turbine flowmeter is my company to measure liquid flow meter in the introduction of Germany advanced signal detection technology, combined with the company's accumulated experience, the use of advanced digital processing equipment, developed a new generation. Sensor with high precision, long life, simple operation and maintenance, which is widely used in petroleum, natural gas, iron and steel, chemical, metallurgy, water, paper, food, medicine and other industries, is the ideal instrument for flow measurement and energy savings.

Two, HNLW-3000Y turbine flow sensor

1. Works
    When the fluid to be measured by the sensors, the impeller is rotated by means of kinetic energy of the liquid within the sensor. At this point, the impeller blades so that the magnetic resistance detection means changes periodically, so that it ends in the detection coil induces an electrical pulse signal frequency proportional to flow, amplified by an amplifier remote output.
    The measurement range, the flow sensor pulse frequency is proportional to the volume flow, the ratio is the meter factor. Represented by K.

    Where:
         k = 3600 × f / Q or K = N / V
         
         f- traffic signal frequency (Hz)
         Q- volume flow (m3 / h or L / h)
         N- number of pulses
         V- of total volume (m3 or L)
    Each sensor meter factor by Hahn (Dalian) Co., fill in fluid control technology verification certificate. K value is set into the supporting instrument display, it can display the instantaneous flow rate and total volume.
