In case you were wondering, Dwyer also makes digital manometers and pressure testers.
The measurement of pressure is almost as old as time. The manometer is one of the foremost means of measuring the pressure of a fluid and is still widely used due to its simplicity and precision. As a thermometer is to measuring temperature, so is the manometer to pressure. Gravity and the density of the liquid play a large role in the accurate detection of pressure using a manometer. By the way, in case you didn't know it, Galileo thermometers use liquid to measure temperature, based upon the principle that the density of liquids change depending upon the temperature.
A manometer functions by measuring the pressure of a fluid/gas by stabilizing it with a stream of liquid. A fluid with already known pressure is used at one end of the manometer to measure another fluid whose pressure is in doubt which is put in the other end. Using a liquid, it can measure the pressure inside a tube and its externals.
You can choose a manometer depending on the kind of fluid/gas you want to measure. If it’s liquid, you should ask yourself: is the liquid miscible with the measuring liquid or not? Is the liquid whose pressure is to be ascertained heavier than the manometric liquid? What is the distance between the two points for which pressure is to be measured? Is the pressure to be measured high or low? Once you get answers to these questions you won’t have a problem choosing the right manometer for your needs.
The widely pictured manometer is typically a U-shaped tube, with liquid that can be water or mercury. Mercury is preferred since it makes calculation easier due to its high density. The tube has slim hands on the two sides and is open at both ends, unlike the barometer, which is a device used to measure atmospheric pressure.
Before choosing a manometer, you have to first consider what you need it for. Is it to be used for personal needs at home, for a school laboratory to take readings and educate students or for research, study and scientific findings? You should also be certain if you want a digital or analog manometer, depending on the purpose it is to serve. As a home user or a professional working with a weather station, a manometer is a priceless gadget; taking pressure readings with it is an easy task, as long as you have the correct one. When you have the right manometer, you just need to learn how to operate it and you are good to go.
Different types of manometers exist in the market and are available at different prices. The differences in their features and functionality may be responsible for the price range. These factors have to be considered if you are going to spend your hard-earned money getting a manometer.
In order to decide what should be the ideal price for a manometer, we have to eliminate the confusion in the minds of our customers regarding what to look out for. Our buying guide is properly detailed and would help you make the right decision. After much research and consideration, we found out that the best manometers are within the price range of $55 to $164. Yes, we found some rather cheap manometers, which were inadequate in some things like features and portability, so we ignored them (and so should you).
Manometers may come in similar or slightly different designs due to the kind of work they are used for. If you want to pick a manometer, you would have to consider carefully some factors that would ensure you get maximum benefit out of the device. Here are the principal factors to consider:
These features listed will enable you to know what to keep in mind as you make your choice of manometer. Kindly continue reading to further glean the implications these factors can have on a manometer.
Recording pressure readings in the comfort of your home or office is totally achievable as long as you have the right manometer and are conversant with its usage. Generally, manometers are simple to operate. There are different kinds of manometers:
A good number of manometers can retain readings, with a ‘freeze’ screen function that enables you to save readings in the device memory. This is a great feature since a log of the pressure calculations you have done for a time period can be easily accessed. When the manometer memory is full, some of the data can be wiped off to make room for a fresh set of readings.
Most modern monometers come with cases, made of durable plastic in which they are carried. The case encloses the main parts of the manometer, preventing them from damage, water and the effects of harsh weather.
Indicator fluids are stabilizing liquids used in liquid manometers to measure the pressure of the liquid under consideration. Water and mercury are the most commonly used ones. Water is a light liquid and is suitable for measuring small and sometimes seemingly insignificant differences in pressure. Mercury on the other hand and other ‘heavier’ indicator fluids are more useful for calculating large variations in pressure. The heavier the indicator fluid is, the higher the range of pressure that the manometer can measure. Other indicator fluids like benzene, colored water and bromides also exist. Before deciding on an indicator fluid to use, you have to consider the prevalent temperature, flash point, vapor pressure and density among other things.
Manometers could be digital or analog. The analog type is one of the oldest forms of manometers. They are usually crafted from sturdy, durable, and pliable polyvinyl chloride (PVC). They offer precise measurement of the pressure of gases and liquids. With an analog device, some calculations are bound to be made after readings have already been taken, which can be tedious.
So here comes the more modern variation: the digital manometer!
Like a breath of fresh air, this device is refined and is a handheld device that is great for calculating differences in pressure and other interrelated factors. It is more specific, has a high reading accuracy and is convenient to handle. It is an incredible tool to have in the house and is useful for checking the propane level of your home appliances like barbecue ovens and indoor grills. They can also be used to detect faults in heat ventilating and air conditioning systems. Digital manometers can be hooked up to your computer. They are portable and suitable for field work, can be mounted on a base or put up on a panel.
Some manometers are available with batteries included, while for some others, you would need to buy them yourself. As soon as you purchase your device, it is advised that you fix in new batteries or replace the ones that the manometer was delivered with. Digital manometers require fresh batteries, as these are important for good calibration and precise readings. Most manometers have a battery-saving mechanism that causes them to go off if left unused for about 20 minutes. Re-illuminating the LED backlight display is just by a push of the power button.
