The on-site level gauge shows no reading
Thread Content
A level gauge was installed at the point where the stripping water is collected in the middle of the distillation tower, but it keeps showing no liquid level. Water can be drained successfully; the lower end of the level gauge is connected to the liquid phase, at a height of about 600 mm, while the upper end is connected to the gas phase. The pipelines are all unobstructed, yet the level gauge doesn’t show any reading. The pressure here is around 55 kPa, and the temperature is less than 110 degrees. I’ve been unable to figure out the reason, and I’m hoping everyone can help analyze it. Thank you.
The following situations may occur: 1. The sensor of the level gauge is faulty or not properly connected, resulting in the inability to receive the level signal. You can check whether the sensor connections are secure and free of looseness. 2. A power supply failure or a problem with the power supply cables of the level gauge results in no power being supplied. You can check whether the power interface and cables are functioning properly. 3. The display device of the level gauge is damaged or misconfigured, resulting in an inability to properly display the liquid level. You can check whether the display device is damaged or if the settings are correct. 4. The measurement principle or range of the level gauge is not suitable for these operating conditions, resulting in an inaccurate measurement of the liquid level. It is possible to check whether the measurement principle and range of the level gauge are suitable for the actual operating conditions. It is recommended that you check the above aspects to identify the problem and take appropriate action. If the problem still cannot be resolved, it may be necessary to invite a professional to carry out on-site adjustment. .
In your picture, only the magnetic flap level gauge and the blowing controller for the air-blown level gauge can be seen. Are you saying that the magnetic flap level gauge has no display?
Is the drain valve a three-way valve? Its opening degree is incorrect
I don’t understand how you installed this; it doesn’t seem like it will work properly at all: lol
“The pressure here is around 55 kPa, and the temperature is less than 110 degrees. ”Under these conditions, the water does not maintain a stable liquid level; the liquid formed in the glass tube quickly returns into the container, so no liquid level can be detected
Under these conditions, it is nearly saturated water vapor
Close the connection valve at the bottom and see if it can be drained
Is it possible that there really is no liquid level inside? With that very low liquid level you have set, it cannot be indicated
Where is the upper part of this level gauge connected to? :L
