The benefits of using a Liquid Filled Pressure Gauge over a dry gauge

The benefits of using a Liquid Filled Pressure Gauge over a dry gauge

Liquid filled pressure gauges are similar to dry utility pressure gauges but are filled with liquid. These types of gauges are suitable for all the same oil, gas, liquid and solid industries as the dry gauges. Typically the liquid inside is a type of oil or alcohol like glycerin or glycerol. Oils are chosen for their high viscosity, meaning that they will resist change as a liquid.

Vibration¬†is any machines worst enemy; it can loosen bolts and parts over time causing the gauge to fail. A gauge is technically a simple machine, which therefore inherits the problems of vibrations that larger machines have. Over a long enough period of time and vibration, any gauge will come apart and fail. The screws, bolts, dials, and fittings will simple rattle away from each other until it is unusable or completely dismantled. Machines or systems that create pressure often have significant vibrations, such an air compressor or power washer. Motorcycles have various gauges on them such as the oil pressure gauge, and are notorious for their heavy vibrations. Many people choose an oil filled pressure gauge for their motorcycle for that reason. The vibrations in automobiles are often dampened for the consumers comfort; nonetheless cars often utilize an oil filled gauge. Aside from completely ruining a gauge, vibrations can make getting an accurate reading of the pressure levels difficult or impossible. Simply airing up your car\’s tires with a compressor can be frustrating when the readout isn’t clear because the dial keeps bouncing around. Over inflating your tires or under-inflating your tires can be dangerous as a driver, passenger, or even the air compressor operator.

Glycerin is oil like substance which has been historically derived from processes such as making soap. Glycerol is a refined version of glycerin that is also an alcohol. Glycerin is a common liquid used in these liquid filled pressure gauges. Glycerin can limit the effect of vibrations significantly if not almost completely. Machines that require consistent readings every time will need to replace their gauge periodically to ensure safety and productivity. The working temperature range for glycerin filled gauges is normally between 30 to 160 degrees. Silicone oil will withstand a wider temperature range (from -50 degrees to 300 degrees), but will also be more expensive.

Liquid filled pressure gauges are certainly a higher quality instrument for any pressure related application. With that being said, these gauges often cost significantly more. If you are using a gauge for something that has large amounts of vibrations you will save time, money and possibly even some lives if you spare the extra dollar initially. Only avoid oil filled gauges if they are not suitable for the temperature ranges that you will be operating in.

Why use Stainless Steel 316?

There are many materials made available to make psi gauges out of, however they aren’t all equal. Some are stronger, some weaker, one material isn’t always better than another the application is what determines the real value of a metal. Buying the highest quality material can get very costly, so you may only need it if the project is meticulous enough or large enough to merit extra expense.

Stainless steel has some favorable attributes to brass and bronze in just about every way except cost. Brass and bronze do have plenty of applications however, it’s likely you have one or both in your home plumbing. Projects that include food, beverages, or increased need for strength should consider stainless steel 316. Stainless steel is more corrosive resistant than the other two. 316 is a stronger and more magnetic version than 304, thus costing a little extra but often worth it. Why is stainless steel 316 (SS316) part magnetic? Basically, the 316 consists of some other metals like ferrite and chromium which are magnetic but make the casing much stronger.

When it comes to psi gauges, pressure gauges, or the better liquid filled pressure gauges one website clearly beats the rest in offering only stainless steel DirectMaterial.com .

How to Gauge Pressure?

How do you gauge pressure? Well it’s pretty simple really, you get a pressure gauge. There are many pressure gauges available, depending on how strong of a pressure you need to measure, size of gauge, connection size, color, or even some liquid filled gauges that stabilize your pressure reading. Typical dry utility pressure gauges are universal and can be applied to most applications, needing only an adapter occasionally.

What is PSI?

PSI is a unit of measurement for pressure. P.S.I. Stands for pounds per square inch. Most pressure gauges in America have a PSI readout, or they may have a metric readout. There are many needs and uses of pressure gauges. Often times the safe operation of a machine or device will depend upon the right pressure, some machines have multiple pressure gauges for multiple pressure systems running. The wrong pressure could cause an accident or just hurt your machine. Despite what type of substance is being measured the gauges are often the same, just different amount of acceptable PSI reading depending on the use.

What is Gauge?

Gauge has many somewhat different meanings. This site is mostly about devices that gauge(to measure) pressure. “To Gauge” something means to measure it. Gauge can also refer to specific sizes of wires, ear piercings, shotgun shells, to name a few.

Gauges are important because they have the ability to let us know of something going wrong before it has too large of an effect. For instance, the oil pressure gauge in your car lets you know when you are running out of oil so that you can get it change or put more in, instead of learning the hard way and having your car shut down or damaged. How about the air pressure gauges you need to make sure your tires have enough air before learning the hard way and having a blown out tire.

Literally all machines or devices using air, oil, or water, or other substances are likely using or could benefit from using one of many types of pressure gauges. There are also liquid filled pressure gauges which are known to stabilize the read-out and by reducing the affect of vibrations.
