Why Select a Thermal Mass Flowmeter?

Thermal Mass Flowmeters are highly accurate and demonstrate high repeatability. This style of flowmeter is available in several different packages that range from basic analog to explosion proof indoor outdoor variations.

Your heavy duty flowmeters will likely have few or no moving parts which mean fewer things to break and maintain. Most offer an alarm system to notify you in the event of emergency which helps to eliminate any downtime which you might experience because of the alarm. This type of flowmeter can also be used with liquid or gas.

Elastomer seals provide excellent leak protection and wards off pressure drop. If you need a seal for a flow stream where contamination is unacceptable invest in a thermal mass flowmeter with metal seals or ultra-high purity seals which are great for use in clean environments such as the pharmaceutical industry.

If you are working with a configuration of pipes that does not offer straight sections of notable length invest in a thermal mass flowmeter that offers a conditioning element as an option. By taking advantage of a conditioning element you can eliminate issues with velocity and temperature distortions which will cause inaccurate readings from your gauge while maintaining little pressure drop.

Many companies are now offering a line of compact thermal mass flowmeters for use in those crammed areas where large flowmeters are impractical. While the size is compact the products still boast exceptional reliability and fast response times. Another type of flowmeter called an ultrasonic flow meter is also compact in size and is great when used as a backup for meters that are already in place!

Depending on which company you choose to purchase your thermal mass flowmeter from you will likely be able to customize your gauge exactly the way you need it. If your pipes are larger than normal or the gas you are measuring is specific, you should be able to find the right gauge for the job.

For flexibility, purchase a thermal mass flowmeter with an advanced electronics package. If you are in the field and need to adjust a setting this type of package will simplify the job on the fly. You can even password protect the package for increased security when utilizing the product in the field.

How Does a Thermal Mass Flowmeter Work?

Every molecule absorbs a certain amount of heat. By providing a heat source in your thermal mass flowmeter and then passing your flow stream through the heat source you can measure the amount of heat that has been dissipated from the heat source. If you increase the flow into the meter the heat will dissipate quicker and therefore you can calculate that the mass is larger.
