The glycerin gauges they are analog mechanisms designed for reading water pressure. These provide us with permanent information on the existing pressure. In addition, they serve to control the perfect operation of certain mechanisms in irrigation systems, filters, pressure equipment or regulators. Glycerine pressure gauges consist of a circular dial and a pointer, which is mechanically actuated.
Glycerin gauges typically measure pressure in bars, as is the case of the ones we have in Mundoriego, although there are also those that measure it in pascals o psi (force per square inch).

Advantages of glycerine manometers
- Glycerin pressure gauges cushion pressure peaks, impacts or vibrations and protect the mechanism. These vibrations, in the long term, reduce the useful life of the device. Thanks to the filling liquid, in this case glycerin, the internal mechanical system is dampened and the parts are lubricated.
- Glycerin prolongs the useful life of the device, since a dry manometer is unprotected against different factors that erode its useful life much faster than one made of glycerin.
- Glycerin pressure gauges provide us with great precision, reliability and resistance.
- They are designed to be installed in environments where there are corrosive elements, dust or high vibrations.
- They minimize the wear produced as a result of being subjected to high vibrations.
- They prevent water condensation at very low temperatures. The filling liquid prevents the peephole from freezing and allows us to obtain a correct reading.
- It can be used in installations with hot and cold water, steam and oils.
- Can work in environments between -20°C and 60/65°C approximately.
Installing a pressure gauge
- Gauges should always measure in a vertical position. The gauge thread can be vertical or perpendicular to the gauge.
- Its installation must be carried out using the appropriate tools for it. Installation should not be carried out by holding the box to prevent breakage.
- The rubber tip at the top should be cut so that internal pressure is not generated as this could distort the readings.
- In general, in the agricultural field the pressure gauges are installed by direct connection, that is, directly to the irrigation network through a sleeve.

I found it to be a very interesting and very useful article.
I would be interested to know how long is the useful life of a manometer
Good,
We do not have a minimum time for the operation of a pressure gauge. The manufacturer has a 2-year guarantee, even so, with good maintenance it should not be damaged or cause any problems.
Sincerely,
The Mundoriego team.
I have an irrigation pressure gauge and it is up to 4, there is a valve for cleaning or zeroing the pressure once installed.
Good,
We don't understand your question, but there are no pressure gauges that can be set to 0 bar pressure manually.
Once installed, the manometer will mark the pressure in the pipe.
Sincerely, The Mundoriego team.
I have several barometers with glycerin installed horizontally and they do not last long, it may not be good to install them horizontally
The pressure gauges can be installed in a horizontal position, since orientation is not a problem.
Most likely, you are working with higher pressures than the manometers can withstand (overpressure), and that is why they break after a short time.
On the other hand, if you are working with pressure ranges that the equipment can read, the problem may be that they are exposed to extreme temperatures that glycerin cannot withstand, such as below -20ºC and above 60ºC. It can also be due to high mechanical vibrations, corrosion by chemical products, or because the box was turned when installing them instead of just the thread.
Goodnight
I would like to know when in doubt.
I live in the countryside and the water in my house is from a well.
I installed a pressure group for the house electric pump, stainless steel expansion vessel, filters, etc.
My question can I change the pressure gauge (6 bars max) from the normal dry ones... to a watertight glycerin one...
I say this in case over the years it breaks down and the glycerin passes into the water circuit.
since we use it to drink the family..
Thank you very much
kind regards

It is very rare for glycerin manometers to break. In the event that they did, as the pipe is under pressure, the water would expel the glycerin to the outside along with the water. However, we cannot guarantee that in the event of breakage, part of the glycerin will not go into the water in the installation. To avoid the risk you can continue with the manometer dry.
Sincerely, the Mundoriego team.
Can a glycerin manometer be sterilized in an autoclave at 121 degrees for a sterile area?
The pressure gauges we supply cannot be sterilized as they cannot be subjected to such high temperatures.
Sincerely, the Mundoriego team.
If the glycerin in the manometers is not completely full, would it still be useful?
Good,
The pressure gauges are not completely filled with glycerin.
The glycerin should occupy 75–95% of the volume of the manometer sphere.
Sincerely, the Mundoriego team.
