Description of the MASSFLOW gas flow controller

Attachment.png

The MASSFLOW is a new mass flow controller system especially designed for use with Lambda laboratory bioreactors and fermenters. For example, it allows control of the pH of a cell culture by the controlled addition of gaseous CO2, the control of dissolved oxygen, by regulation of the airflow or any other gas with a suitable controller. However, it can also be used independently, since all functions can be controlled from the front panel of the MASSFLOW.

The gas flow rate is measured by high quality laminar mass flow sensor tubes and is displayed on a digital display. The mass flow cell has a very low pressure drop (less than 1 cm of H2O) and a linearity error of less than 3 % reading (which is much better than the precision expressed as a percentage of full scale used by some manufacturers). The repeatability is better than 0.5 % per reading. The gas flow rate is regulated by a specially developed proportional needle valve controlled by a microprocessor.

The MASSFLOW gas flow controller can be operated manually with the buttons on the front panel or using remote control. The analogical remote control includes ON/OFF and 0 to 10 V full-scale control of the flow rate. A fully digital control uses RS485 connection.

Programming

Up to 50 pairs of flow rates and times can be programmed. This allows the flow to be switched on and off or the setting of any flow rate for a desired time interval.

Gas volume totaliser

The MASSFLOW gas flow controller generates impulsions after every 5 ml of gas flow. These impulsions can be totaled by a Flow Integrator (cat.no: 4803), measured as a voltage, recorded on a recorder or on a PC (fermentation program FNet). In this way exact volume information can be obtained.

Zero setting

The MASSFLOW gas flow cotroller is equipped with an automatic zero setting which further improves the precision of the gas flow rate reading.
