Product Description
Product description
The LWGY series turbine flowmeter is optimized by absorbing the advanced technology of domestic and foreign flow instruments. It has the characteristics of simple structure, light weight, high precision, good reproducibility, sensitive response, low installation and maintenance, and convenient use. It is widely used in petroleum and chemical industries. , Metallurgy, water supply, papermaking and other industries, it is an ideal instrument for flow measurement and energy saving. Detailed Photos
Working principle
When the measured fluid passes through the sensor, the impeller rotates under the action of the fluid, and its speed is proportional to the average flow velocity of the pipeline. The rotation of the impeller periodically changes the magnetic resistance value of the electrical converter. The magnetic flux in the detection coil changes periodically to produce a periodic induced electric potential, that is, an electric pulse signal, which is amplified by an amplifier and sent to the display instrument for display.
Product features
High accuracy, generally up to ±1%R, ±0.5%R, high-precision type up to ±0.2%R;
Good repeatability, short-term up to 0.05%~0.2%
Output pulse frequency signal, suitable for total measurement and computer connection
High frequency signal (3~4kHz) can be obtained, with strong signal resolution
Wide range, medium and large diameter 1:20, small diameter 1:10
Compact and lightweight structure, convenient installation and maintenance, and large circulation capacity
Suitable for high-pressure measurement, the meter body does not need to be opened, and it is easy to make a high-pressure meter
Various types of special sensors can be customized according to users, such as low temperature type, two-way type, downhole type, special type for sand mixing, etc.
Can be made into plug-in type, suitable for large-caliber measurement, low pressure loss, low price, can be taken out continuously, easy to install and maintain
