Which type of level gauge is suitable for measuring the liquid level in horizontal tanks?
Thread Content
Let’s discuss a question: For level monitoring in a closed horizontal tank with dimensions of 6 meters by 2.6 meters, which type of level gauge would be suitable? The medium in question is a mixture of oil and water, under normal temperature and pressure conditions. It is required that the level in the tank can be adjusted in conjunction with the outlet control valve. I have used double-flange differential pressure transmitters and electric float level gauges in the past
Float level gauge, magnetic flap level gauge
The operating conditions are favorable and the medium has no special properties, so there are many methods that can be used. The cheaper options are as follows: 1. Magnetic flap level gauge with remote transmission (fluorescent version), which not only solves the problem of displaying the liquid level on-site but can also be used in applications where high control precision is not required. 2. Submersible level gauges are inexpensive and easy to install; the main consideration is that the cable material must be suitable for use in oil-filled environments. 3. Others such as single-flange low-range pressure transmitters (at atmospheric pressure) are also acceptable.
The South or the North? Environmental factors should also be taken into account ； For some level gauges with side-mounted bypass designs, instrument heating needs to be considered in northern regions
You can use the one you used before. Why not use it anymore. Is something wrong?
For safety reasons, we used magnetic flip switches as well as float balls
Crude oil, heavy oil, or light oil? Ambient temperature? You need to make these clear, haha.
Is there a separation interface in the oil-water mixture? It’s very important to determine whether you are measuring the interface or the liquid surface!
We have used it in the operating conditions you mentioned, with the addition of a guide tube, and it is used with lidar or 26G pulse radar
Float level gauges – they work fine for both liquid level and interface level!
I understand that oil and water will form a mixed interface. Therefore, it is necessary to clarify which interface is intended to be measured. Interface measurement agrees with what was said above – a float should be a good choice.
