Cross-sectional air flow measurement device performance characteristics and technical indicators :
Performance characteristics:
1. Although the flow velocity through each point on the pipe cross-sectional wind measuring device is not constant, it is required to be stable. In the occasion where the pipeline installation environment is harsh, a flow regulator is used and placed upstream of the speed measuring device. Its role is to convert an unstable fluid into a bundle of stable fluids within an equal length for accurate measurements.
2. Because the flow velocity through the pipeline cross-section measuring device at each point is not equal, it is required that the value measured by the sensor be as close as possible to the average value. Structurally, the average of the sum of the velocity at each point is generated. The detection probe detects the total pressure and static pressure of the air flow in accordance with the principle of multi-point automatic balance pitoting.
3, no straight pipe before and after, as long as there are 250 ~ 300mm long installation position.
4. It can measure airflow at an angle of 30° without being affected by irregular fluids or even multi-rotating airflow.
5, does not require on-site calibration, that flow coefficient K = 1.
6, the pressure loss is very small.
7. The positive pressure hole and the static pressure hole are in the direction of flow, which greatly reduces the possibility of blockage.
Technical indicators:
1, the shape of the pipeline: rectangular and circular shaped pipes.
2. Accuracy: 1%, 1.5%.
3, repeatability: ± 1%.
4, diameter: 50 ≤ D ≤ 5000mm.
5, working temperature: -50 ~ 450 °C.
6, working pressure: 0 ~ 16Mpa.
7. Reference standards: GB/T2624-2006, GB1236-2000 and JJG835-93.
8, connection: flange connection, welding.
9, the gas flow rate needs to be greater than 4m/s.

Electric polishers are commonly used for polishing stone materials such as granite, marble, engineered stone, tile and more. These polishers are a great option for on the job work since no compressor is needed like with an Air Polisher. Electric polishers are available in a variety of brands and speeds.

 

Selection

Our selection of electric polishers is large with such polishers as the Legend Countertop Polisher designed for concrete and the FREWSP-2 Variable Speed Polisher perfect for engineered stone as a slow speed RPM range which eliminates burning or scorching the work piece.

 

Safety

It is important to remember with an electric tool the use of a gfci is necessary for safety. Polishers like the FREWSP-2  Electric Polisher come already equipped with this very important feature. The use of safety glasses is recommended when using any type of polisher.
