Learn how pins on our transmitter contact the electrodes of the flow tube and transfer the signal of the fluid to the electronics, providing a volumetric flow rate in the video above. There are no electronic parts in the flow tube itself in the video above.
Full Bore With No Obstruction
Our innovative Electromagnetic Flow Sensors can help to streamline your bioprocessing, allowing for minimal hold-up volume – full bore with no obstruction.
Overview
Our Krohne FLEXMAG 4050C Sensor consists of 3 parts, the transmitter, the gamma stable and autoclave stable flow tube, and the monitor. The flow path is designed to have minimal hold-up volume – full bore with no obstruction. Pins on the transmitter contact the electrodes of the flow tube and transfer the signal of the fluid to the electronics, providing a volumetric flow rate. There are no electronic parts in the flow tube itself.
The transmitter is the source of the magnetic field and signal conversion. The transmitter can accommodate two different flow tube sizes, which provides the flexibility of being able to handle two different flow ranges by simply exchanging the tube without having to re-calibrate. Our FLEXMAG 4050C Sensor also features a single barb fitting that meets biopharmaceutical requirements for adaptation to single-use systems.
