Benefits of Variable Area Flowmeters and How to Choose One

Variable Area Flowmeters | Flowmetrics

If you want to keep tabs on the rate at which your gases or liquids are flowing, consider using variable area flowmeters to do the job effectively. These meters measure flow in a cross-sectional area and makes changes in response to the flow. The variable area variety of meter is simple to operate and is chosen for its efficiency in measuring both liquid and gas applications. Those who need this type of meter will find that these devices are economical and can be installed in just a few steps on the vertical section of the tube. In addition, there are no tubing run requirements for variable area flowmeters. The end caps located on the flowmeters can be removed easily and cleaned as needed. This makes troubleshooting and inspection simpler and can enable you to check the proper functioning of the meter at regular intervals.


Structure of Variable Area Flowmeters

These meters have a structure designed for industrial applications and sturdiness for extended use. They have tapered glass tubes that are mounted vertically on a steel frame. When at rest, the float stays at the lower part of the tube, and with increased flow, it rises with hydraulic forces to reach equilibrium. When this happens, a certain level is reached which is altered only with exchange and the rates of flow. In addition to the glass tubes with steel casings, variable area flowmeters have steel bezels at the front and behind with sturdy safety shields. Most flowmeters can be mounted in-line or on a panel. Different sections of the meter are sealed with secure “O” rings which are tightened with pressure.


Industrial Area Flow Meters

One of the most popular types of variable area flowmeters is industrial models designed for all kinds of materials and for fast and slow gas and liquid flow rates. The meters have a horizontal fitting that can be rotated 90° at a time. The seals connect the tube in the frames firmly with safety shields and the meters are secure and protected from wear and tear. There are ports at the top and bottom of the meter that make inspection and cleaning simple, and the meters can be mounted easily on any kind of workspace. These kinds of meters have multiple applications over a variety of different industries. Common uses include hydraulic component test benches and polyurethane foam production.


Flow Metering Panels

Flow metering panels are designed for absolute precision in industries that demand absolute accuracy. The meters are accompanied by a custom engraved scale that is located close to the metering tube. The scales display data from calibrations with the use of liquids that follow the pattern of the flow. These panels can be accompanied by certain pipes and valves for greater efficiency. There are several options for fitting and mounting, and you can choose between horizontal and vertical flanges.


High-Pressure Meters

If you prefer an in-line flowmeter, you can find one that is designed for high pressure and can be fitted with vertical or horizontal lines. These high-pressure area flowmeters are made of stainless steel or aluminum with durable seals made of the strongest materials. They can withstand extremes of pressure and temperature and can tolerate intense activity.


What to Look for in Variable Area Flowmeters

Whether you are purchasing a variable area flowmeter for the first time or are replacing existing equipment, it is essential to know how to make your selection and what your industrial needs are. The main focus of all these meters is to make sure that the machinery is functioning well. The kind of device you choose depends largely on the type and size of your machinery. You should also have a working knowledge of the typical flow rate of gasses and liquids in your production and have an idea of what you can expect. Do a thorough inspection of your production process before shopping for a variable area flowmeter to assess your company’s needs.

It is best not to be penny wise and pound foolish when it comes to choosing an area flowmeter. You could find a less expensive model made of cheaper materials, but if your gasses and liquids leak, that could cause a significant amount of waste and you may have to pass the costs on to your customers. You can prevent this from happening by purchasing the best meter after some comparison shopping among quality suppliers before making your final decision. Also, make sure that all equipment comes with a warranty and that the company working with is dependable and has plenty reviews available on the Internet.

Think about what kind of materials you are using on a regular basis. Heavier materials require more pressure to create a flow and may move more slowly. Other liquids make their way through more quickly. Choose a meter that suits the average speed of the materials you are using. Calculate an average rate of flow of the materials used in production.

Look for a company that handles installation as well as sales. If your valves and joints are not positioned properly, this can affect the accuracy of your reading, so check that all of the equipment is installed properly and work with the company you can trust and which will make repairs as necessary at low cost.

You should also consider other equipment to enhance the performance of your area flowmeter. Look for a company that offers a variety of machinery that you might need including RF pickups, batch controllers, flow computers and field indicators. Make sure you have the right size of the area flowmeter and the type that you need for the materials you use in production. Gasses and liquids flow at different rates and take this into account when selecting new meters. These products are used for a variety of applications including chemical, aerospace and pharmaceutical industries as well as food and energy production. The importance of these services and products cannot be underestimated and therefore the most accurate and efficient equipment is required to ensure flawless results under all temperatures, pressure, and conditions. Make sure your meters come with a guarantee and are inspected often.
