If you are looking for a Mopeka gas cylinder level sensor for your motorhome or caravan, you are probably wondering: what is the difference between the Mopeka Pro Check and the Mopeka Pro Check Universal sensors, and which one should you choose?
In appearance and operating principle, the two Mopeka sensors are quite similar. Both use ultrasonic technology, measuring the liquid level in the tank through the bottom of the container, and send the reading via Bluetooth to the Mopeka app.
However, the Mopeka Pro Check Universal is not simply the Pro Check under a new name. It is a further developed and more versatile sensor with better measurement accuracy, longer battery life and a much wider range of uses.
What is the Mopeka Pro Check?
The Mopeka Pro Check is designed primarily for measuring the level of propane, butane and LPG mixtures.
In a motorhome or caravan this usually means one very specific task – quickly finding out how much gas is left in the cylinder.
On a steel cylinder, the sensor attaches under the bottom of the cylinder using built-in magnets. The sensor measures the liquid gas level using ultrasound and sends the result via Bluetooth to the free Mopeka app.
This makes the Mopeka Pro Check a very convenient motorhome gas level sensor, because you no longer need to:
- lift
- weigh
- shake
- knock
- or try to guess how long the gas will last.
On your phone you can see how full the cylinder is in a moment.
What is the Mopeka Pro Check Universal?
The Mopeka Pro Check Universal uses the same principle, but it is a more versatile and technically further developed model.
The main differences are measurement accuracy, battery life and the range of liquids that can be measured.
1. The Pro Check Universal is more accurate
The Mopeka Pro Check has a measurement accuracy of up to 99%, while the Pro Check Universal reaches up to 99.5%.
If you only use an LPG gas cylinder, this difference is not necessarily a reason to replace a working Pro Check sensor. But if you are buying a new Mopeka level sensor today, the Pro Check Universal is the technically newer and more accurate solution.
2. The Pro Check Universal has a longer battery life
Both sensors use a replaceable CR2032 battery.
The typical battery life of the Mopeka Pro Check is about 2–4 years, while the Pro Check Universal lasts roughly 3–5 years, depending on use and operating conditions.
In a motorhome, longer battery life is a clear advantage – the less often you have to deal with the battery of the sensor under the cylinder, the more convenient it is.
3. The Pro Check Universal measures much more than LPG
This is the most important difference between the two models. The Mopeka Pro Check is primarily a gas cylinder level sensor.
In addition to LPG, the Mopeka Pro Check Universal can measure several other liquids, for example:
- propane
- butane
- LPG mixtures
- clean water
- grey water
- diesel fuel
- oil
- various chemicals
- and other suitable liquids.
That is why the name Universal is fully justified. The same type of sensor can be used not only on a gas cylinder but, with a suitable installation, also to monitor the level of a motorhome's water tank or diesel fuel tank.
Mopeka Pro Check vs Pro Check Universal – main differences
| Feature | Mopeka Pro Check | Mopeka Pro Check Universal |
|---|---|---|
| LPG / propane / butane | Yes | Yes |
| Water | No | Yes |
| Grey water | No | Yes |
| Diesel | No | Yes |
| Oil and other liquids | No | Yes |
| Measurement accuracy | up to 99% | up to 99.5% |
| Battery | CR2032, replaceable | CR2032, replaceable |
| Typical battery life | 2–4 years | 3–5 years |
| Bluetooth | Yes | Yes |
| Mopeka app | Yes | Yes |
| WiFi Bridge support | Yes | Yes |
| Magnetic mounting on a steel cylinder | Yes | Yes |
| Measuring different liquids | Limited | Yes |
Is the Mopeka Pro Check Universal suitable for a standard 11 kg gas cylinder?
Yes. If you use a standard steel LPG cylinder in your motorhome, the Pro Check Universal attaches under the bottom of the cylinder with magnets, just like the Mopeka Pro Check.
In everyday use both are equally simple: sensor under the cylinder → Mopeka app on your phone → gas level on the screen.
That is why the Pro Check Universal is also a great fit for someone who only wants to monitor a standard gas cylinder.
What about aluminium and composite cylinders?
A magnet does not stick to an aluminium or composite cylinder. In such cases you need to use a separate mounting or installation solution suitable for the sensor.
The same applies if the Mopeka Pro Check Universal is installed on, for example, a plastic water or fuel tank.
Before choosing a sensor, it is therefore always worth checking three things: what you want to measure, what material the tank is made of, and what shape the bottom of the tank has.
Which Mopeka sensor should you choose?
Choose the Mopeka Pro Check if:
- you only want to monitor the level of an LPG gas cylinder;
- you need a simple, proven solution;
- you do not plan to use the sensor to measure water, fuel or other liquids.
The Mopeka Pro Check does an excellent job of measuring the gas cylinder level.
Choose the Mopeka Pro Check Universal if:
- you are buying a new sensor today and want the newer model;
- you want longer battery life;
- you want maximum measurement accuracy;
- you want to use the same type of sensor on other tanks too;
- you want to measure water, diesel, oil or some other suitable liquid;
- or you simply prefer the most universal solution possible.
Is it worth replacing an existing Mopeka Pro Check with a Pro Check Universal?
If you already have a Mopeka Pro Check, it works properly and you only use it to monitor a gas cylinder, there is no real need to replace it. The Pro Check is still a very good and practical gas cylinder level sensor.
But if you are only choosing your first Mopeka sensor, the Mopeka Pro Check Universal is the more technically advanced and future-proof choice, especially if the price difference between the two models is small.
Mopeka Estonia – which sensor suits your motorhome?
The difference between the two models can be summed up simply: the Mopeka Pro Check is a very good LPG gas cylinder level sensor. The Mopeka Pro Check Universal is its more versatile further development – more accurate, with longer battery life and able to measure many other liquids in addition to LPG.
If you only want to monitor the gas cylinder level in your motorhome, both models do the job very well. But if you are buying a new sensor today and want the most universal and future-proof solution, the Mopeka Pro Check Universal is our preferred choice.
