Sales of LWGY turbine flowmeter LWGY-25 turbine flowmeter supply

Description :

　　This product is widely used in the measurement and control systems of petroleum, chemical, metallurgical, scientific research and other fields. It can display the total flow, instantaneous flow, and flow saturation percentage.

　　1、 Technical parameters:

　　Measurement caliber: Pipeline type: DN0.5~DN600;

　　Accuracy level: ± 0.2%, ± 0.5%, ± 1.0%;

　　Environmental temperature: -20 ℃~+50 ℃;

　　Medium temperature: Measurement liquid: -20 ℃~+120 ℃;

　　Nominal pressure: 1.6 Mpa, 2.5 Mpa, 6.4 Mpa, 25 Mpa;

　　Explosion proof grade: ExdIIBT4;

　　Connection methods: threaded connection, clamp connection, flange connection, plug-in connection, etc;

　　Output function: Pulse output, 4-20mA two-wire current output, with RS485 communication interface.

　　2、 Characteristics:

　　1. Good repeatability, with a short-term repeatability of up to 0.05%. If calibrated regularly, very high accuracy can be achieved, and ideal results can be obtained in quantitative feeding and quantitative barrel loading operations.

　　2. High precision. For liquids, domestic products can achieve ± (0.2-0.5)% R, while some foreign products can achieve ± 0.15% R.

　　3. Output pulse frequency signals, which can be connected to batch controllers and flow display meters for signal processing without increasing errors.

　　4. Simple, compact, lightweight, easy to install and maintain, with high circulation capacity. If a malfunction occurs, it will not affect the transportation of liquid in the pipeline.

　　5. Pulsating flow with low inertia, fast response, time constant of 1-50ms, and low rate of change can introduce negligible errors.

　　6. Corrosion resistance: The sensor is made of corrosion-resistant materials and can withstand corrosion from general corrosive media.

　　3、 Precautions for use:

　　When using, the tested liquid should be kept clean and free of impurities such as fibers and particles.

　　At the beginning of use, the sensor should be slowly filled with liquid before opening the outlet valve (which should be installed at the back of the flowmeter). It is strictly prohibited for the sensor to be impacted by high-speed fluid when it is in a liquid free state.

　　The maintenance cycle of sensors is generally six months. During maintenance and cleaning, please be careful not to damage the parts inside the measuring chamber, especially the impeller. Please pay attention to the position relationship between the guide components and the impeller during assembly.

　　When the sensor is not in use, the internal liquid should be cleaned, dried, and protective covers should be added at both ends of the sensor to prevent dust and dirt from entering, and then stored in a dry place.

　　The matched filter shall be cleaned regularly, and the internal liquid shall be cleaned when not in use. Like the sensor, it shall be sealed with dust cover and stored in a dry place.
