The Brooks Nrooks mass flow controller is used to measure flow rate for aerospace, pharmaceutical, and energy industries. Regardless of the application, Brooks E mass flow controller calibration is important to ensure accurate flow measurements.

These pieces need to be tested periodically to make sure that readings are valid. The tube directs the flow inside the controller. The flow is directed to pass an upstream temperature sensor, then a heater, and finally a downstream temperature sensor.


The heat is directed toward the center of the tube. During flow, heat is moved away from the upstream sensor towards the downstream sensor. The temperature difference between the sensors is proportional to the gas flow rate.

A frequently seen issue that impairs Brooks E mass flow controller calibration is damage to the internal tube. Cleanliness of the internal tube can also have an effect on the instruments calibration.

Through continual testing, the technicians at our Northeast Ohio calibration laboratory have noted issues that arise from a damaged or dirty tube. The severity brrooks vary from a slight bend to a fully collapsed tube.

A clogged or dirty tube will not provide accurate readings. Damage can impede or block flow. During the Brooks E mass flow brioks calibration process, a technician verifies that the instrument is performing correctly.

If a mass flow controller fails testing, the technician will investigate the cause of the issue. If the internal bfooks is found to be damaged, the technician can replace it.


If the tube is found to be dirty or clogged, the technician can clean the tube depending on the severity of the clog. Calibration testing will take place after tube replacement or cleaning. The owner also has the option of replacing the mass flow controller.
