Flange type liquid turbine flowmeter

Product Details

The LWGY series flange type liquid turbine flowmeter is the main type of velocity type flowmeter. When the measured fluid flows through the turbine flowmeter sensor, the impeller is forced to rotate under the action of the fluid, and its speed is proportional to the average flow rate of the pipeline. At the same time, the blade periodically cuts the magnetic field lines generated by the electromagnet, changing the magnetic flux of the coil. According to the principle of electromagnetic induction, a pulsating electric potential signal will be induced inside the coil, The frequency of the electrical pulse signal is proportional to the flow rate of the measured fluid.

Product Characteristics

High precision, generally up to ± 1% R, ± 0.5% R, and high-precision models up to ± 0.2% R;
Good repeatability, such as frequent calibration or online calibration, can achieve extremely high accuracy, and is the preferred flow meter in trade settlement;
Equipped with three point correction for instrument coefficient, intelligent compensation for instrument coefficient nonlinearity, and capable of on-site correction;
Maintain all valid data for 10 years after power failure;
Wide range, medium to large caliber can reach 1:20, and small caliber can reach 1:10;
Compact and lightweight structure, easy installation and maintenance, and large circulation capacity;
Suitable for high-pressure measurement, there is no need to open holes on the instrument body, making it easy to make high-pressure instruments.
