MC & MCR Series Laminar Mass Flow Controller Products |
VC & VCR Series Laminar Volumetric Flow Controller Products |
 |
| The Alicat line of Laminar Mass Flow Controller products utilize a proportional valve coupled to a mass flow meter body. Measurements are taken within the laminar region of the mass flow meter and the integral PID controller positions the valve to maintain the user programmed set points. The mass flow controller and volumetric flow controller offer single or dual output signals of the same or different voltages and/or different parameters such as mass flow and temperature or flow and pressure. These robust, closed-loop devices can accept and transmit 0-5Vdc, 0-10Vdc, 4-20mA or RS232 control signals, depending on customer preferrence. Flow controllers range from 0.5 CCM full scale to 1,500 SLPM full scale and all flow control devices include a dynamic digital display that simultaneously shows all the process parameters being measured by the meter plus a push button operator interface for set point adjustments, gas select and tare. |

Mass Flow Controller and Volumetric Flow Controller Applications |
|
0-0.5 SCCM up to 0-50 SCCM Mass Flow Controller and Volumetric Flow Controller products
Accurate full scale flow ranges as small as 0.5SCCM allow customers to precisely control tiny quantities of gas. This nearly unique ability is commonly used in the emerging Micro Electro- Mechanical (MEMs) field, as well as pharmaceutical and semiconductor manufacturing. Laboratories and universities across the globe have also used these devices to control flows in a wide variety of research projects requiring precise, accurate, miniature process controls. |
|
0-100 SCCM up to 0-20 SLPM Mass Flow Controller and Volumetric Flow Controller products
Mass flow controller and volumetric flow controller products in this range are commonly used for small process control either in manufacturing or research. Many of these units have found their way into fuel cell research and development projects while commonly used in fuel cell test stations. Their fast and multiple simultaneous reporting of temperature, pressure and flow, as well as their excellent control characteristics make them ideal for research. Their reliability and multiple parameters also makes them ideal for process control and trouble shooting. |

0-50 SLPM up to 0-1500 SLPM Mass Flow Controller and Volumetric Flow Controller products
Mass flow controller and volumetric flow controller products in this range are often used in light industrial applications including control of weld gases, control and monitoring of shaping air paint applications (guns and bells), monitoring air in powder delivery systems, equipment for emissions regulations compliance (SKID benches) and quality testing of critical systems on the shop floor. The adjustable response time and user control over the terms of the P.I.D. is exceptionally helpful in these applications. |
