The ST100 Series Thermal Mass Flowmeter from Fluid Components International (FCI) is now available with FCI’s VeriCal In-Situ Calibration Verification System, combining measurement capability with in-situ calibration verification. The VeriCal In-Situ Calibration System allows for the verification of flowmeter calibration in minutes without removing the meter from the pipe or process and is intended to help meet process validation more effectively and comply with environmental regulation requirements. The VeriCal In-Situ Calibration System and the ST100 Flowmeter Series are designed to comply with the U.S. Minerals Management Service (MMS) mandate that stipulates that all domestic U.S. offshore rigs processing more than an average of 2,000 bopd must install flare/vent gas flowmeters.
