Mass Flow Controllers

OEM customers and system integrators have realized thousands of dollars in savings by switching to Alicat mass flow controllers.

With a 200:1 turndown ratio, Alicat MFCs are allowing OEM customers to replace 2, or sometimes even 3, MFCs with a single Alicat MFC. Machine builders and integrators are using Alicat MFCs to reduce up front tool costs and inventory requirements for their customers without sacrificing performance.

Mass flow controllers (MFCs) are becoming more common in applications which require the delivery of accurate gas flow. Alicat Scientific’s mass flow controller is a feature rich and customizable product that is designed to delivery maximum flexibility and performance. Alicat MFC’s can be ordered in flow ranges between 0.5SCCM and 3000SLPM with control speeds of 50ms to stabilize even the most unstable gas sources. Alicat MFCs also come standard with a fully functional push button display that allow users access to the majority of the controller’s settings without the need for specialized controls or software; 30 on board user selectable gas calibrations allow users to change process gases on the fly without the need for costly and time consuming recalibrations; 200:1 turndown ratio allowing the controller to flow as low as 1/200th of it’s full scale range; And, the industry’s only, lifetime warranty which can save hundreds of dollars in repair costs over the life of the controller.
The Alicat mass flow controllers are engineered to meet the following design criteria:

Simplicity

The MC series mass flow controller is very easy to use. With the local display, users can make changes to the configuration of the unit without the need for computers, complicated software or scripts.

Mass Flow Controller Accuracy

Alicat MC series mass flow controllers can be configured with an accuracy spec of up to +/-(0.4% of reading + 0.2% of full scale) with a high-accuracy calibration. Standard calibrations are rated at +/-(0.8% of reading + 0.2% of full scale)

Mass Flow Controller Repeatability

Alicat’s patented technology allow its mass flow controllers to have very few moving parts. All of the MFC’s internal components are fixed in place resulting in very little physical change inside the MFC. Little physical change in the flow cavity means higher rates of consistency and repeatability. Alicat MC series mass flow controllers have a repeatability of +/-0.2% of FS

Reduced Cost of Ownership

Alicat MC/MCP/MCR series flow controllers require very little power to run thereby reducing operating costs. MC and VC series flow controllers also have less pressure drop when compared to similar flow devices. Reduced pressure drop means more process fluids go into your process and not into your measurement devices. The MC series mass flow controllers also measure pressure, temperature and volumetric flow in addition to mass flow which means fewer instruments you will have to buy and install.

Control Speed

The Alicat MC/MCP/MCR series mass flow controller has a response time of less than 10ms and a control time of 100ms making it one of the fastest naturally responding mass flow controllers on the market today. Watch an Alicat mass flow controller responding to set point changes.

Versatility

MC series mass flow controllers are available in any flow range from 0.5SCCM through 2000SLPM. The MFCs are equipped with multiple analog outputs and inputs. Adding a totalizer allows users to see how much media has flowed through the MFC, making it a great way to monitor usage and identify waste.
Alicat MC/MCP/MCR series MFCs can also be used in applications where flow control into a vacuum is critical. The modular design of the Alicat MC/MCP/MCR series MFC allows it to be used in systems in which flow is driven by a vacuum.

Dependability

Alicat mass flow controllers around the world are being used in processes like pharmaceutical and semiconductor manufacturing, fuel cell research, auto paint application, and emissions compliance equipment.

Alicat Scientific mass flow controller calibrations are NIST traceable.
