Installation issues with guided wave radar level gauges
Thread Content
As shown in the figure, the guided-wave radar level gauge is installed outside the cooling water tank. What is the reason for this? Or what’s the advantage of installing it this way? Why not insert it directly into the tank from the top? I think there are two reasons for this design: 1. The tank contains equipment such as agitators, which makes it difficult to install a guided-wave rod radar level gauge. 2. Installing it in this way facilitates disconnecting the instrument from the system, making maintenance easier. However, in the case of cooling water tanks, these two factors are not present. I hope experienced experts in instrumentation can provide guidance and explain the reasons for such an installation! Also, if any other friend from Sichuan has documents on instrument installation specifications, could they share them so we can learn together*! Thank you, thank you:lol
The tank has a small volume, resulting in large fluctuations in the liquid level during loading and unloading, which affects the measurement accuracy. Therefore, a bypass pipe is used to install the level gauge. The bypass flange design allows not only the installation of radar level gauges but also other types of level gauges, such as float level gauges and magnetostrictive level gauges.
For the selection of instruments related to the \"SHT3005-2016 Specifications for the Selection and Design of Automation Instruments in the Petrochemical Industry\", you can refer to this guide; I hope it will be helpful to you!
It’s also possible that your tank is too small; the original level gauge isn’t suitable for it. Once the tank is built, it’s no longer possible to install a guided wave tube, which is why an external floating ball guided wave radar was used instead. In my opinion, a floating ball level gauge would have been sufficient……
You started preparing to install a magnetic level gauge, but later, for some reason, you bought a radar instead, right? ;P
So rich! Guided wave radar for water measurement. The installation method is explained very clearly on the second floor. The small diameter of the tank causes water inflow and outflow to interfere with the radar level gauge; furthermore, the open top of the tank makes it inconvenient, so a bypass pipe is used for installation.
So, what kind of gauge is used for measuring water levels that has a lower cost? Differential pressure level gauge?
Using radar for condensate water is also a waste! Installed on the bypass pipe, it not only facilitates delivery but also helps to stabilize the liquid level
What I really want to ask is, Radar, will installing it like this cause a lot of interference? It seems like this bypass pipe is quite thin
Float and magnetic flap level gauges are the most economical. For greater accuracy, immersion-type level gauges, capacitive sensors, and radio frequency admittance level gauges are all relatively inexpensive.
What generosity! ! ! It seems that the pressure tap at the root is also working well, right? A ball valve? Is the cooling water tank a very important piece of equipment in the process? Is there control? What is the rate of change in liquid level?
