Rotameter Flow Meter

The rotameter flow meter represents a device or a tool that is generally used to measure the flow rate of a liquid solution or a gas inside a container or tube. Liquid flow meters are also very important. The general construction of a rotameter flow meter consists from a tube that varies in size and shape and contains a floating device that raises in level once it is subjected to increased flow rate and is pulled down by the force of gravity. At a higher flow rate of liquid or gas there is a greater are of free space needed inside the container thus the floating device or he float raises to accommodate the increase. 

The floating devices are manufactured from different materials and they are also varied in shape and size however the most common encountered types being spheres and ellipsoids. The floating device also needs to have a rotary shape to permit the rotameter flow meter to fulfill it’s attributions. 

The readings that the rotameter flow meter provides can usually be read in the top part of the cylinder of the top side of the floating device. When gases are included in the equation the floating ability of the device is put to the test and the measurements rely  mostly on the floe speed of the gas.

The rotameter flow meter can be incorporated in devices that are varied in materials such as glass, metal and plstic.

The rotameter flow meter also comes with several features that offer advantages and disadvantages. For that respect I will enumerate most of them so the choice you take will be based mostly on information. The features are :

•  
  • it does not require an external power source or fuel to power it thus the costs are greatly reduced as for the proper functionality of the device.
  • it uses the natural abilities of the gas or the liquid used and based on flow speed and gravity in takes accurate readings.
  • it is designed to be a simple device and it relies also on simple principles thus the manufacturing process is not complicated and also the costs for producing this device are greatly lowered. 
  • because it uses the natural principle of gravity the rotameter flow meter must always be positioned in an upright position and the gas or fluid must flow upward.
  • the rotameter flow meter requires the use of transparent materials in it’s manufacturing process so the end product will not be highly resistant to vibrations or shocks and could break easily. 
  • When purchasing a rotameter flow meter you also need to take into consideration the following variables :

•  
  • what would be the minimum or maximum flow rate that you are searching for in such a device. If you are focused on using this device for industrial purposes than you need to increase these values.
  • the size of the type is also important when purchasing this measuring tool.
  • would you require a valve to regulate the flow of fluids or gas inside the container thus customising the power of the rotameter flow meter.

•  
  • No matter the purpose you have intended for the rotameter flow meter you know have some basic knowledge regarding it’s properties and features so choosing the best one for you is now an easier task. http://www.waterflow-meters.com/ provides more info about this topic.
