A Simple Guide on How to Read Rotameter

When it comes to Rotameters, the method of gauging flow is achieved by a freely flowing float the parity in a tapered pipe. The Rotameter is arguably thought to be in its second century in the market. Below is a simple guide on how to read a rotameter.

How to Read a Rotameter

Many factors affect the performance of a flowmeter. Such factors include raising the density and weight of the float. That means you will need to increase the flow rate to force the ball up to any height in the pipe.  

You need to note that the working pressure is supposed to be at the pipe’s outlet if the valve is at the inlet. That is done to aid in the working state to that at the calibration of the Rotameter.

The Rotameter’s accuracy relies on the pressure, heat, and flow control accuracy during calibration and operation. Sensors are designed to very tight tolerances in materials.

That is mixed with accurate and precise calibration methods that enable the meter to be rated as one scale division. It would be best if you aimed at the upper half of the scale for your flow range when specifying a rotameter.

Do you wish to know how to read a rotameter? If yes, then you landed in the right place. Below are the steps to follow when reading a variable area meter.

First Step

 Firstly, you need to set up your meter on a flat surface. That is very vital in ensuring that the meter is level. Suppose your meter is too large to stand on its own, done worry. You can use clamps to attach the meter to be a bit firm.

Second Step 

Once you are done setting your meter, go ahead and look for the ball floating in the middle of the meter column. Check at the bottom of the ball to see where it lines with the scale on the side of the meter. Note that you may need to buy tubing links from a hardware shop.

Last Step 

In this step, look for the ball floating in the middle of the flowmeter column. If you manage to get the place it lies, then that is the flow rate. The Rotameter is always marked from top to bottom, raising and lowering flow, which is the same as a thermometer. Typically, the scale varies depending on the mark found on your meter.

Remember, if you wish to set the flow rate at a specific level, you can use a knob or even a dial on your sensor. Go ahead and move it either up or down until the ball’s base reaches the rate of your choice. But, ensure you operate in a well-ventilated region when handling toxic gases.

Benefits of Using a Rotameter

There are many merits gained when using a flow meter. Some of the main pros of using this meter include:

  • There is no external power needed.
  • Rotameter is a device that does not need any power to measure the flow rate of fluids. That means that you can install your meter in a remote area that does not have power and save the cost of supplying power.
  • It is very affordable.
  • The meter is very cheap to acquire, enabling you to work on a tight budget and save your money.
  • They are easy to install and maintain.
  • Rotameter has a low-pressure drop.

Final Word

Despite this flowmeter’s long stay in the market, many users still love it up to date. That is because Rotameter is an economical way of gauging low to high flow rates. Use the above guide as a reference every time you need to know about flowmeter reading.
