The BFC100 Bubbler Flow Calibrator provides the convenient and cost effective solution to the calibration of Bubbler flow controllers. In-situ calibration provides NIST traceability, minimal down-time, and cost savings. The Bubbler and the flow controller stay in place; therefore, the costs of down-time, Bubbler service technician time, calibration service, and shipping/handling are eliminated.

1. Experience in the design, fabrication, maintenance, and evaluation of Bubbler instruments since 1981
2. Evaluation of several designs and components over several years has established a knowledge base for quality and reliable construction
3. Well documented operating and maintenance procedures provide detailed information
4. Comprehensive Quality Assurance testing performed and documented on each production unit
5. Capabilities include calibration of mass flow devices, digital meters, and complete instrument operational evaluation
6. On-site, telephone, fax, and e-mail support are provided during and after the “front panel to back panel” one (1) year guarantee of materials and workmanship.

Calibration gas, typically ambient air, enters the instrument through the rear “IN” port and flows through a filter then a precision mass flow meter before leaving the instrument through the rear “OUT” port. The precision flow meter is calibrated with records traceable to NIST. A Bubbler flow controller/meter in series with this instrument receives a Transfer Calibration traceable to NIST. The BFC100 is re-certified at least annually to maintain this traceability.
