Water well level measurement with Proteus EcoMeter

Level Q&A

Hi. I'd like to use an EcoMeter to measure the level in my cistern, but I have a question regarding the wireless communication. Our cistern has a metal lid. Will it still work?

Expert’s answer: Water well level measurement with Proteus EcoMeter

Excellent question! You definitely need to check your communication for your installation, but in this case, the solution is simpler than you might imagine.

Let’s start with some context. The EcoMeter, a low-budget level transmitter from Proteus, collects level data wirelessly. You can pick one of three models. While their specs differ, they all will measure up to three meters in a cistern up to 19,999 liters in volume. (Note that the vendor requires a minimum of 15 centimeters between the sensor and the maximum level.)

As for your communication, yes, the metal lid can attenuate the wireless signal. However, you only need to install a remote antenna with an extension cable to get around this problem. The EcoMeter has an optional cable to connect the sensor to the antenna. Then you can install the antenna outside the tank with the sensor inside. Now, the cable only reaches up to nine meters, but this installation will ensure your reliable communication.

You also have a few ways to install the sensor, depending on your structure and application. But in general, your tank needs to sit within range, your sensor needs enough distance from the cistern wall, and you need a good signal for your communication.

Other solutions

If you decide the EcoMeter won’t work for your application, then you need to take a look at other similar devices. I picked two examples, so let’s take a look.

FMR10 from Endress+Hauser

This entry-level radar has all the benefits of radar technology, plus you can set it up and see all the data using the SmartBlue App with the built-in Bluetooth protocol. It can work with analog and HART communication too, if you need those instead to integrate it into your control system and check your data.

If you want to learn more about the FMR10, then read our product review here.

Senz2 radar level transmitter

Another good solution, the compact Senz2 has an internal battery and GSM communication, making all your data available through an internet portal.

Here, if you change your metal lid to a polymer one, then you can install the device outside the cistern. Because of its technology, it can measure through the polymer lid without any problems.

You can read more about the Senz2 in our product review. Be sure to watch our video review at the end too!

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?
