Mass flow controllers (MFCs) were originally designed to take the guess work out of precision gas flow control. Today, the demand for accurate and repeatable gas flow control has spanned dozens of industries. Demand for mass flow controllers is growing and customers are requiring that MFCs are easy to use, fast, reliable, accurate, cost effective and robust.
The Alicat MC series mass flow controller is designed to meet the above requirements:
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 and VC/VCP/VCR 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.
Versatility
MC series mass flow controllers are available in any flow range from 0.5SCCM through 1500SLPM. 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
There are currently over 22,000 Alicat products in service around the world. Alicat mass flow controllers 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.
