Why Have A Liquid Filled Pressure Gauge?

Liquid filled pressure gauge

A liquid filled air pressure gauge is generally preferred and used for two main reasons, ROI and performance. Today, most liquid filled gauges are really a glycerin filled pressure gauge. This is because a glycerin filled pressure gauge will optimally perform in conditions that are less-than-ideal.

Liquid Filled Gauges vs Dry Gauges

Dry gauges are still used today in both commercial and industrial machines. However, dry gauges have some major drawbacks. Many times, they can be damaged from vibration, which causes incorrect readings. Moisture can also get inside of the gauge, which can obscure the reading. Also, if the moisture freezes, the whole gauge will more than likely stop working.

Liquid filled pressure gauges are used for the same pressure ranges as a dry gauge, but they can also go much higher. Liquid filled gauges are designed to dampen vibrations, so the gauge is easier to read and ensures that the readings are precise. There is also no need to worry about moisture and freezing when using a glycerin filled pressure gauge.

Advantages Of Liquid Filled Pressure Gauges

There are a number of advantages that liquid filled gauges have over dry gauges. Here are some of the main advantages of using a liquid filled air pressure gauge.

• Longer Life Spans

Generally, liquid filled gauges will have longer life spans than dry gauges because of the glycerin in them. This means that you need to replace your tire pressure gauge less often. This design advantage results in lowered instrumentation costs because the fluid protects against severe temperature fluctuations and vibrations.

• More Accurate Readings

The glycerin inside of the gauge readout makes the reading more accurate. This is because the dial cannot be shaken easily with any vibration. The lower vibrations also ensure that the gauge provides accurate readings for a longer time period. Improved readings are important because you have more control over the amount of pressure that is in the tire.

• Easier To Read

Depending on your climate and the environment, dry gauges are sometimes going to be difficult to read. A gauge that is not readable is worthless, which is why liquid filled gauges are used in areas that have high humidity. Even in the high humidity, liquid filled gauges are easy to read because moisture cannot enter the face plate of the gauge. Freezing temperatures are also not a huge worry since the liquid could be a mixture of glycerin and silicone which is often used in extreme temperature conditions.

Liquid filled pressure gauges are a very good option when you are looking to buy a tire pressure gauge. Liquid filled gauge readings are more accurate, and they are much less likely to be damaged from freezing temperatures.
