A Guide Into Mass Flow Controller

A mass flow controller is a device that regulates the flow of liquid and gas. It controls them at a specific range of flow rates. For perfect accuracy, it is given a set point from 10 degrees to 90 degrees. 

There are two types of devices- a digital and an analog one. Both have distinct features in their roles. A digital mass flow controller can regulate more than one fluid, yet an analog one is only limited to the fluid calibrated to it. Parts of the device include. 

  • Inlet Port 
  • Outlet port 
  • Proportional Control Valve 
  • And a sensor. 

For perfect optimization, an external input gets signaled into the device. It then uses a control loop system to function. 

It also demands a continuous supply of gas or liquid that comes at a constant amount of torque. If it gets too much pressure, it may result in false figures. Less torque will also affect its functioning. 

So, what are its Advantages 


Putting up a pressure transmitter and an ancillary temperature may get costly. For a transducer, it may even cost you up to $800 per unit. Keep in mind that you have to pay an expert to install it in your own home, resulting in more expense. Putting up the mass flow controller eliminates that. You get a device that works better and also requires minimal capital cost. 

No In-motion sections

It uses high tech, meaning you will not observe any moving parts. It gets protected by a stainless-steel sheath, and the heat passes over resistance temperature detectors (RTDs).

Simple to Put Up

It is not hard to install by yourself. Simply 

  • Ensure that the piping is clean. Run it with water to eliminate any dirt. Give it some time for the water to dry up. 
  • For a steady liquid or gas stream, put up a filler upstream. If you expect a backflow, do not forget to install a downstream filler. 
  • Ensure that the piping has the correct diameter. If it doesn’t, then there is a high chance it can cause turbulence. Turbulence will affect the results. The diameter should be about ten times the interval between the angle and the inlet of the instrument. 
  • Put it away from any nearby heat source. It should also be in a horizontal position. 
  • Do a final thorough check to avoid any leak. Once you are positive, it is in working condition, apply the fluid pressure. It will warm up for about thirty minutes. 

Ensure to read the tool’s nameplate for assurance. Double-check the sealing material for compatibility. Only apply for pressure when the electrical connections get made. Failure to do that will result in an error. The fittings should also be tight. See this link to read more https://fluidhandlingpro.com/smart-mass-flow-controllers-improve-bioprocessing-results/.

They have a big range-ability ratio.

Turn-down ratio(or range-ability) means the scope in which a device can precisely measure any fluid. This specific device has a range-ability ratio of 100 to 1. It means that the devices are likely to give out accurate measurements. 

Unaffected by Pressure Variations. 

A dynamic change in pressure can alter the response of any fluid. It is what we call pressure variations. For this device, you do not have to worry about any pressure variations. If there is an altercation of the pressure, then it will affect the volumetric flow rate. 

It will still give out the required results since it prioritizes molecules. They also have a low-pressure drop. With that, it will consume less energy. They can sense any light directed at the gas line. 

Other benefits include:

They have a usual calibration verification. You will not need to remove the flow meter to check on the measurements. Lastly, it is easy to maintain them.

What to consider when opting for one. 

Identify the main action.

Get to know the vital function of the device. Where will it fit? In case you are not sure about its role, consult an expert. With that, you will minimize the possibility of errors happening in your home. You may also do extensive research about the product. Weigh your options from different sellers before settling on one. 

Which Median will it attend? 

We have gas, air, or liquid matter that the device handles. It is your job to know in which field the apparatus will take care. 

By that, you will know what type to get for your house. Be aware that temperature conductivity, pressure, and even viscosity can tamper with the apparatus. 

Different types of gases and liquids behave differently at specific pressure ranges. By identifying which media, the device works on, it will be easy to predict the future movement. 

Will it be very accurate? 

Depending on its purpose, the device has to outlay the result. If the device is in an anesthesia machine, the outcome will determine the health of an individual. You ought to know just how efficient the apparatus is. Click here to read more insights.
