The Brooks 5850E mass flow controller is used to measure flow rate for aerospace, pharmaceutical, and energy industries. Regardless of the application, Brooks 5850E 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.
Mass Flow Controller Tube
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.
Tube Damage Effect on Brooks 5850E Mass Flow Controller Calibration
A frequently seen issue that impairs Brooks 5850E 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 can 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. In this instance, the mass flow controller will not function properly unless the tube is replaced or cleaned.
During the Brooks 5850E mass flow controller 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 tube 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.
