EL-FLOW Select F-201CV
These gas mass flow controllers & meters can be paired with your pressure reactor to allow accurate measurement and control of flow ranges between 0,16…8 mln/min and 0,5…25 ln/min at operating pressures between vacuum and 64 bar.
The mass flow controller consists of a thermal mass flow sensor, a precise control valve and a microprocessor based PC board with signal and fieldbus conversion. As a function of a setpoint value, the flow controller swiftly adjusts the desired flow rate.
Key features of these mass flow controllers include:
- High accuracy
- Fast response, excellent repeatability
- Optional Multi Fluid / Multi Range functionality
- Virtually pressure and temperature independent
- Compact design
The EL-FLOW Select series are equipped with a digital pc-board, offering high accuracy, excellent temperature stability and fast response. The main digital pc-board contains all of the general functions needed for measurement and control. In addition to the standard RS232 output the instruments also offer analog I/O.
As an option, an on-board interface can be mounted to provide CANopen®, DeviceNet™, EtherCAT®, PROFIBUS DP, PROFINET, Modbus RTU, ASCII or TCP/IP, EtherNet/IP, POWERLINK or FLOW-BUS protocols. The EL-FLOW® Select design features optional Multi Gas / Multi Range functionality, providing (OEM-) customers with optimal flexibility and process efficiency.
Other models/specifications are also available.
