High quality high precision Graphite Scraper Flowmeter
1.Graphite scraper flowmeter is a kind of high precision volumetric flowmeter, designed to provide high precision measurement design for refined oil trade settlement, and can be widely used in gasoline, aviation kerosene, diesel and other light fuel measurement.
2.Graphite scraper flowmeter has high accuracy, good repeatability and reliable and stable measurement performance. When the flow meter is running, the rotor rotates at uniform speed, no pulsation, low noise and large flow rate, and the accuracy is not less than 0.2 in the range of greater than 10:1.
The LBJ Series Graphite scraper flowmeter is designed for the high precision requirements of light fuel metering, each flowmeter is a complete and strict performance test after passing the factory, plus regular standard maintenance can maintain its long-term high precision and good reliable performance.
The LBJ Series Graphite scraper flow meter integrated with local display of M1 large word counter, A5/A6 counter or BELZ electronic counter, M1 large word local display and A5/A6 display can show the total cumulative amount of measurement and a single cumulative amount, by supporting the tachometer can also measure the instantaneous flow of fluid through the flow meter, The BELZ electronic counter can display the cumulative flow and instantaneous flow at the same time, and can also realize the pulse and 4-20mA current electrical output, Hart communication or RS485 communication output.
Main features:
The LBJ Series LBJ graphite scraper flowmeter is a kind of high precision positive displacement flowmeter, due to its exquisite and reasonable structure design, has the following characteristics:
1.When the flowmeter is running, the rotor rotates at a constant speed, the rotation is smooth and no fluctuation, low noise, and the fluid in the pipeline has no pressure fluctuation.
2.Graphite material or PTFE material scraper has wear resistance and self-lubrication, small running damping, to ensure the stability of the measurement performance.
3.The range ratio of measurable flow is large, up to 15:1.
4.High measurement accuracy, the basic error is better than ±0.2%, good repeatability.
5.No straight pipe section length restrictions, reduce the installation space.
6.Avariety of types of counters to choose from, to achieve local indication and a variety of electrical signal output remote transmission.
7.Reliable mechanical properties, small maintenance, long machine life.
8.The whole single shell structure design, simple and compact mechanism, small size, easy installation and maintenance.
