MKS® GV50A Digital Mass Flow Controller
Multi-gas/multi-range, elastomer sealed, digital mass flow controller for rates up to 50 slm with a incorporated shut-off valve
The GV50A digitally-controlled mass flow controller is available with either RS485, Profibus™, EtherCAT®, or DeviceNet™ I/O. The digital control electronics use the latest MKS control algorithms for fast and repeatable response to setpoint throughout the device control range. Typical response times are on the order of 600 to 800 milliseconds. Digital calibration yields 1% of setpoint accuracy on the calibration gas. I/O protocols are designed to allow the GV50A to easily replace RS485 and DeviceNet™ versions of the MKS 2179A MFC with minor coding.
GV50A incorporates a normally-closed, shut-off valve for closure to 4x10E-09 scc/sec of Helium. It incorporates few elastomers - only one external elastomer seal and elastomer valve plug. All wetted surfaces are metal. The GV50A comes standard with Viton® seals or optional Buna, Neoprene® or Kalrez® to support different gas requirements.
Features & Benefits
- Patented thermal sensor design for exceptional zero stability
- Percent of setpoint accuracy enables precise process control
- Embedded user interface - easily change device range & user gas, monitor & measure performance

* The Full Scale flow rate is designated by a 3 digit number. The first two digits represent the significant digits of the Full Scale flow rate separated by a decimal point. The third digit is the exponent of the power of ten.
** The user should consult with their gas supplier on the appropriate elastomer which is compatible with the selected gas.
Free, downloadable software that allows for simple monitoring and configurations of the MKS MFC.
