    BRONKHORST® General Product Information 1.1 Introduction This user guide covers the EL-FLOW Base Series mass flow controllers for gasses as shown in the pictures below. Included herein is product information, installation instructions, operation, maintenance, troubleshooting and technical specifications. F-201CB F-201AB...
  • Page 6: Warranty

    BRONKHORST® 1.5 Warranty The products of Bronkhorst® are warranted against defects in material and workmanship for a period of three years from the date of shipment, provided they are used in accordance with the ordering specifications and the instructions in this manual and that they are not subjected to abuse, physical damage or contamination.
  • Page 7: Model Key

    The instrument is fitted with either Viton or Kalrez seals. Which sealing material is used is shown in the last character of the model key. Bronkhorst® has gathered a material compatibility chart from a number of sources believed to be reliable. However, it is a general guide only. Operating conditions may substantially change the accuracy of this guide.
  • Page 8: Calibration

    BRONKHORST® 1.6.4 Calibration EL-FLOW Base instruments are Air or N2 calibrated. Bronkhorst® certifies that all instruments meet the rated accuracy. They have been calibrated using measurement standards traceable to the standards of the Dutch Metrology Institute (VSL). The calibration is converted to the customer’s gas and conditions using a detailed conversion model.

  • Page 10: Solenoid Valve Principle

    1.7.3 Solenoid Valve Principle The control valve used in the EL-FLOW Base series is a standard, direct operated control valve. It is a normally closed solenoid valve. The plunger is lifted by the force of the magnetic field of the coil. The diameter of the orifice under the plunger is optimised for the customer’s application.
  • Page 11: Installation Instructions

    The preferred mounting position of EL-FLOW Base mass flow controllers is horizontal. Other mounting positions may introduce a zero shift and/or little gas and pressure dependency of the zero signal. When 9.17.061 EL-FLOW Base Series Mass Flow Controllers Page 11...
  • Page 12: Fluidic Connections

    Swagelok RS-type adapters combined with AS013 (70°Sh) o-rings for leak tight installation. Bronkhorst® highly recommends the use of Swagelok RS-type stainless steel adapters, e.g. part number SS-400-1-4RS. Adapters can be ordered separately to the instruments. Contact your local distributor for more information.
  • Page 13: Electrical Connections

    Refer to Hookup EL-FLOW Base, document nr. 9.16.091, for more details. Bronkhorst® recommends the use of their standard cables. These cables have the right connectors and if loose ends are used, these will be marked to prevent wrong connection.

    Setpoints below 2% of the full scale will be interpreted as 0% setpoint. When operating the instrument through the analog interface it is possible to connect the instrument simultaneously to RS232 or Modbus/RS485 for reading/changing parameters (e.g. controller response or other fluid selection). 9.17.061 EL-FLOW Base Series Mass Flow Controllers Page 15...

    BRONKHORST® 3.4 Basic RS232 Flowbus operation RS232 Flowbus communication can be used for operating your instrument using the Bronkhorst® FLowDDE server application. Physical layer and communication protocol are detected automatically upon reception of messages. These messages must be sent using the correct combination of physical layer and communication protocol.

  • Page 19: Slave Address, Baud Rate And Parity Setup

    Default instruments will be delivered to customers on address 1 and with a baud rate of 19200 baud and EVEN parity. The slave address, baud rate and parity of the Bronkhorst® meter/controller Modbus slave can be changed to fit the instrument in your existing Modbus network. Changing the slave address, baud rate and parity can be done in the following ways.
  • Page 20 “310: Fieldbus2 baudrate” must be selected. And to read/change the parity parameter “336: Fieldbus2 parity must be selected”. To change one of these parameters parameter “7: Initreset” has to be set to ‘64’ first. Page 20 EL-FLOW Base Series Mass Flow Controllers 9.17.061...
