Product details

Place a turbine in the center of the pipeline, supported at both ends by bearings. When the fluid passes through the pipeline, it impacts the turbine blades, generating a driving torque on the turbine, causing it to overcome friction torque and fluid resistance torque and rotate. Within a certain flow range, for a certain viscosity of the fluid medium, the rotational angular velocity of the turbine is proportional to the fluid flow velocity. Thus, the fluid velocity can be obtained by the rotational angular velocity of the turbine, and the fluid flow rate through the pipeline can be calculated. The speed of the turbine is detected by a sensing coil installed outside the casing. When the turbine blades cut the magnetic field lines generated by the permanent magnet inside the casing, it will cause changes in the magnetic flux in the sensing coil. The sensing coil sends the detected magnetic flux periodic change signal to the preamplifier, amplifies and shapes the signal, generates a pulse signal proportional to the flow rate, and sends it to the unit conversion and flow integration circuit to obtain and display the accumulated flow value; At the same time, the pulse signal is also sent to the frequency current conversion circuit, which converts the pulse signal into an analog current quantity and indicates the instantaneous flow rate value.

1. Characteristics

① High precision ② Good repeatability, such as frequent calibration or online calibration, can achieve extremely high accuracy, making it a preferred flowmeter for trade settlement.

③ Excellent output signal: outputting pulse frequency signals, suitable for total measurement and connection with computers, without zero drift Strong anti-interference ability, strong signal resolution, wide range, compact and lightweight structure, easy installation and maintenance, and high circulation capacity; Suitable for high-voltage measurement, easy to make into high-voltage instruments; Can be made into an insertion type, suitable for measuring large diameters. ⑤ Low pressure loss, low price, can be removed without interruption, and easy to install and maintain.

2. Application scenarios
