What is good for measuring the liquid level in phenol tanks and formaldehyde tanks?
Thread Content
The phenol tank is always heated by steam, while the formaldehyde tank does not have such heating; both are 7-meter tall tanks, with the mounting opening at the top being only 15 cm away from the tank wall. The top of the tank is curved, and waveguide radar is considered for use – I’m not sure if there will be any issues related to residue accumulation
Why is it called a false alarm? Could you explain in detail?
Radar sensors do have many problems; it’s best to avoid using them whenever possible. Why wasn’t a simple and practical level gauge like the single-flange type considered during the design phase?
For the issue of volatile residues, it is recommended to use the admittance method
In this situation, guided wave radar is a better choice than conventional radar. The issue of material accumulation can be avoided by selecting the right type of radar; if you need help, feel free to contact me then
The radar’s installation location is also not suitable; it’s too close to the tank wall
Introducing the rod-mounted director radar! Toxic and volatile; it can easily cause condensation on the antenna tip of horn-shaped radars, leading to frequent false alerts indicating that the tank is full. Formaldehyde can also be measured using a double-flange plug-in level gauge!
Phenol tends to cause deposition and deposition-related issues; both external and pressure-type level gauges are not very effective for measuring it. If a guided-wave radar level gauge is used, it requires regular maintenance – any deposits need to be removed. The same applies here as with sulfur: there is no perfect level gauge. Those who claim that radar level gauges have various shortcomings either don’t understand how to select them properly or are not familiar with radar technology. Only by choosing the right radar for the specific operating conditions can such problems be avoided. If the selection is incorrect or if the radar isn’t suitable for those conditions yet people insist on using it anyway, it’s not the fault of the instrument. Radar level gauges have many advantages but also have certain requirements regarding operating conditions; they’re not a universal solution. Don’t be too harsh. For example, in the case of the formaldehyde storage tanks mentioned earlier, using a guided-wave radar level gauge eliminates any issues related to dew formation or deposition
