Applications

• Process gas measurement in food industry, chemical and petrochemical industries, in fermentation installations and in biotechnology
• Sample gas measurement in environmental analysis
• Gas consumption measurement for internal accounting
• Systems for environmental air sampling
• Hydrogen techniques
• Burner control
• Flow control in formic acid production
• Controlled supply of oxygen for iron removal in drinking water production

Digital Features and Fieldbus Interfaces

All models of the IN-FLOW series are equipped with a digital pc-board, featuring self-diagnostics, alarm and counter functions, digital communication and remotely adjustable control settings. These digital instruments from Bronkhorst offer great flexibility their instruments with an on-board interface with CANopen®, DeviceNet™, EtherCAT®, PROFIBUS DP, PROFINET, Modbus RTU, ASCII or TCP/IP, EtherNet/IP, POWERLINK, or FLOW-BUS protocol.

Approvals for Hazardous Locations

IN-FLOW Series mass flow meters and controllers can be configured for use in explosive environments with FM Class I Division 2 approval, up to a pressure rating of 400 bar (5800 psi).

Multi Gas / Multi Range Functionality

IN-FLOW instruments with Multi Gas / Multi Range (MG/MR) functionality offer greater flexibility for user selection of both flow ranges and gas types, maintaining high accuracy and turndown range for measurement and control. Thanks to this feature, mass flow meters / controllers can be rescaled on site, saving time (and money) for mounting and dismounting. For the convenience of the user, Bronkhorst has developed an easy-to-use software tool called “FlowTune” for changing the configuration of instruments with activated Multi Gas / Multi Range option (available up to 10 bar operating pressure; to be specified at the moment of ordering).
