Not everyone has the mechanical knowledge necessary to find the variable area flow meter that they need. There are several common types that satisfy the needs of the majority of people: in-line, single flow and multi-stage flow, all with unique characteristics that make them function differently. Educate yourself on the technicalities of your problem and the flow meter that you want so that repairs and constructions can be easier.
In-Line Flow Meters
An in-line meter is a high-pressure machine installed on horizontal and vertical pipe lines. It typically measures water, oil, hydraulic fluids, acids, glycerin, naptha and cotton seed oil. It is used for residential or commercial purposes. Quality in-line meters typically resist shocks and vibrations and have alarms that can alert people when the pressure is too high or low.
Make sure to select a product with the correct gallons per minute (GPM) capability, seal, fitting and size measurements. Anything from stainless steel with a Teflon seal to aluminum with Viton is available.
Single Flow Meters
Single flow meters offer a little more sophistication than in-line models. Many have a custom scale attached that allows for direct reading of measurements. They are used in any different industries, including aerospace, military, chemical, pharmaceutical and energy, for applications such as foam production and bench testing.
Take the time to decide on a proper precision accuracy rate, flow and pressure rates and temperature requirement to eliminate unnecessary features and save money. Many of these flow meters last a good 15 to 20 years, and more efficient models are always being developed. It is worth the time to speak to a professional who can give you valuable advice and information about the latest models.
Multi-Stage Flow Meters
Multi-stage meters have pressure reduction capabilities for temperature control and an internal filter. If needed, a sensitive valve provides highly accurate readings. Since multi-stage products typically have anywhere between two and four tubes, there are many customization options available for interstage piping and valving, and end fittings.
To protect yourself against future malfunctions, search for products that have a warranty; you might find a quality product that is guaranteed up to one year. Finding the right multi-stage meter can increase your machines’ productivity and efficiency, saving you time and money. Every industry is different; purchasing the right product can have big payoffs for companies heavily dependent on mechanical liquid flow, such aviation manufacturers or laboratory facilities.
Installing Your Flow Meter
Once you purchase an appropriate model, it is time to install it on your machine. Many figure out how to do it themselves, but to ensure that your meter is functioning properly it never hurts to turn to an expert. Many companies have professionals that provide installation and calibration service that you can take advantage of to make sure your meter is tweaked precisely so you can receive optimal benefits.
With a little research, you can decide which flow meter is truly right for your needs. A reputable company that has been in business for a long time and has strict testing standards for its products is your best bet for answers if you have any questions.

It is essential to have air- release valves when designing a system piping. As air pockets accumulate in a system, the air -release valves will vent the pockets. According to an article by Hydraulic Institute, “If the pipeline is fairly flat and the inside surface of the pipe is very rough, or if the pipeline slopes downward, the fluid velocity may not be sufficient to keep the bubbles moving”. This can cause pockets of air to form at the high points and will begin to effect the liquid flow areas.
