Using proprietary technology, the Masterflex® flow controller measures, controls, and logs fluid path information. It receives input from a flow sensor and then responds by adjusting the speed of your Masterflex pump to maintain a set flow rate or dispense volume. On the 4.3” LED touch screen, simply select the size of the ultrasonic flow sensor connected to the controller, then choose either continuous mode or volume dispense mode.

In continuous mode, the controller will vary the output to the pump to automatically maintain the desired flow rate set point.
In volume dispense mode, the controller will run the pump at a selected flow rate until a selected volume set point has been pumped, then the flow controller will stop the pump operation. Repeat dispensing can be triggered through a footswitch or tapping the start icon.

Log date-and-time stamped entries of flow rate, flow set point, pump speed, and total flow onto a 32GB microSD card installed in the controller. The log file is in CSV format, easily imported into programs such as Microsoft® Excel® for further data analysis and plotting.

Levering: Includes 24 V power supply, USB microSD card reader, preprogrammed 32 GB SD memory card, RJ45 cable (6 ft), DB9 adapter, and DB25 adapter.
