Release time:2017-09-29   Clicks:875
Oval gear flowmeter of Shanghai Automation Instrumentation Co., Ltd. is a kind of volumetric flowmeter, which is a kind of high precision in flow meter. In order to ensure the accuracy of the flowmeter measurement, the correct installation is very important. By the Shunda flow meter technology Xiaobian for the user to explain the correct installation of the oval gear method:
1. Oval gear flow meter should be installed before the filter, the two shells on the arrow pointing in line with the direction of flow.
2. When the measured liquid contains gas, the oval gear meter should be installed before the gas separator.
3. The elliptical gear shaft in the elliptical gear flowmeter is installed in a horizontal position, regardless of whether the pipe is mounted vertically or horizontally. (Dial should be perpendicular to the ground)
4. Oval gear flow meter in the correct installation, if you can not easily read the reading, you can turn the counter 180 ° or 90 ° can be.
5. Oval gear flow meter before the installation of bamboo stick from the exit at the exit of the gear several times, if found immobile, can be soaked with gasoline (to avoid factory calibration after the memory sediment)
6. Throttle valve should be installed in the oval gear flow meter inlet, switch valve installed at the exit, in the opening and closing of the valve to start slowly, do not quickly open or close the valve.
7. Do not use sweep steam through the oval gear flow meter.
8. In the continuous use sector, oval gear flow meter need to add bypass pipe.
9. Oval gear flow meter installed before the pipeline to be washed, flushing with straight pipe (instead of oval gear flow meter position) to prevent welding slag, debris, etc. into the oval gear flow meter.
10. Oval gear flowmeter consisting of water-proof cast iron.
11. Oval gear flow meter in use when the size of the flow shall not exceed the technical requirements. The oval gear flowmeter operates at a maximum flow of 50 to 80% optimum.
12. The measured liquid, if chemically corrosive, must be made of corrosion-resistant stainless steel oval gear flow meter.
