We believe it is important for our clients and partners to have an active voice in the functionality and future development of the Flow-Cal applications. To ensure this industry accountability, Flow-Cal formed the Flow-Cal Advisory Board (FAB-8). The FAB-8 consists of eight respected industry leaders, each representing a critical link within the energy value chain. The FAB-8 represents Flow-Cal’s customers by providing application guidance and helping our product managers set priorities. The directors are elected by their peers and charged with gathering and sharing their group’s needs and best practices. The FAB-8′s role is to prioritize these needs in a way that satisfies all sectors of the industry.

Get Involved

The FAB-8 directors hold quarterly sector meetings to provide a forum for identifying and prioritizing technologies, best practices and strategies that are critical to each industry sector. We encourage participation and invite the user community to attend these meetings. You may sign up for any of the FAB-8 sector distribution lists by clicking the Join FAB-8 button. Prior to the meetings, you will receive an invitation via email with instructions. The meetings are held in a GoToMeeting format, which requires phone and internet connection.
