Boiler level measurement: Do you need a radar?
Hi, I have an application to measure the level of my boiler! We had a lot of problems with pressure transmitter in the past, could you tell me if the radar has a better performance for boiler level measurement!
Expert’s answer: Do you need a radar for boiler level measurement?
Boiler level measurement can be a challenge depending on the technology you want to implement.
The thing is:
If you want to implement a differential pressure for this kind of level measurement, the problem is the mechanical installation.
You see, boiler level measurement requires an equipment to support a high temperature. Usually, the differential pressure application requires a seal pot between the level transmitter and the boiler. But unfortunately, the seal pot often causes problems related to level measurement.
Because of the steam inside the boiler, the level of the seal pot can cause problems. That difference will increase the error of the level measurement. Furthermore, your device might be incorrectly installed. Plus, you might have a low-quality pressure transmitter and a bad setup. Unfortunately, all of these factors increase the problems.
Here, the radar level transmitter can be a great solution. The time-of-flight principle is not affected by the steam and the pressure and gas phase changes in the boiler.
For this kind of application, you can implement a guided radar as a type of radar. The gas compensation is an important feature to have a great and accurate level measurement. Moreover, the installation is usually in a bypass that’s separate from the tank.
Below you have a list of guided radars on the market. You can implement these in your boiler level measurement.

Radar level measurement
Could you please explain how radar works to measure level? So you’re wondering how radar level measurement works? We can certainly explain this. Radar level meters work based on the time of flight (TOF) method or time domain reflectometry (TDR).
Pressure – Measurement troubleshooting
We’re a multinational company based in the Caribbean and have purchased DP level transmitters for our tank farms. We installed the same devices in our new plan in northern Europe, but we noticed that the measurements are not correct. Could you please advise us regarding the source of this problem?
Level transmitter malfunction
We have the Endress+Hauser Levelflex FMP51 installed on a diesel tank for level measurement, but its output is not changing proportionally to the tank level. In the control room, we simulated different currents from the transmitter function menu and the transmitter responded fine. What do we need to fix?
