Instrument level gauge installation problems
Thread Content
When installing the glass plate liquid level gauge and external float level gauge on the equipment, the distance between the two flanges of the equipment port is 200mm shorter than the actual liquid level gauge. During on-site installation, is it possible to add a short pipe behind the valve and then use an elbow to adjust the size? Also, should we ensure that the upper flange of the liquid level gauge is level with the equipment port, and use an elbow to adjust the lower part? Or should we ensure that the lower flange of the liquid level gauge is level with the equipment port, and use an elbow to adjust the upper part?
It can be adjusted by adding a short tube, which is generally level with the lower equipment port.
After adding the short pipe, when the liquid level drops below the lower flange mouth, according to the principle of the connector, the liquid level in the outer float will no longer change. Personally, I think that once the flange mouth is determined, the measuring range cannot be changed. Unless the container is open, adding a short tube on it will be effective.
What you said on the third floor makes sense, I agree!
1st Floor, I would like to ask if there are liquid and gas coexisting inside the glass plate level gauge and external float level gauge equipment. The lower part is liquid and the upper part is gas. If so, the lower part is aligned.
Reply to the person above, there are liquids and gases coexisting inside the equipment, and it has been installed on site according to the lower part alignment. thank you all
The glass plate level gauge and the external float level gauge are both made using the principle of a joint, so you can add a short pipe behind the valve, and then use an elbow to adjust the size! Since the lower part of these two liquid level gauges is connected to the liquid and the upper part is connected to the vapor phase medium, and the upper part is nearly 10% of the measuring range, it is ensured that the lower flange of the liquid level gauge is flush with the equipment port, and the upper part is adjusted with an elbow.
I think whether it is consistent with the lower flange of the equipment or the upper flange, the key is to first know whether the liquid level meter is mainly used to monitor low liquid level or high liquid level.
It should be aligned with the lower flange and the upper part with an elbow. You need to pay attention to the clarity when selecting the model in the future.
study* The distance between the instrument port flange and the length of the liquid level gauge are inconsistent. Is there something wrong with the design?
