Oil Refineries, well drilling operations (such as off shore oil rigs), waste water treatment plants chemical processing plants, natural gas plants, and landfills are but a sampling of applications where waste gases are flared. Flares are subject to stringent regulations, requiring operators to measure, record and report the amount of flared gases. Requirements to monitor the flow rate and consumption of flare gas may involve measurement at points within a complex series of feeder and header pipes, as well as the actual flare stack. In addition, monitoring of the flare output provides important information for process control.
Sage Insertion Style Thermal Mass Flow Meters provide the wide turndown required to cover both the extremely low flows (low velocities) associated with normal venting, as well as the extremely high flows (high velocities) associated with an upset condition. Their fast response to flow changes, low pressure drop, and reproducibility are significant characteristics for a flare application. In addition, Sage Flow Meters provide the customer with a unique procedure, the In-Situ calibration Check, at a “No Flow” (0 SCFM) condition. This important procedure, assures that the Flow Meter has retained the original NIST traceable calibration, verifies the meter’s accuracy, confirms that the sensors are clean, and that the Flow Meter hasn’t drifted or shifted. This is a tremendous benefit, since it eliminates the cost and inconvenience of annual calibrations on the flow meter, and also provides the data needed to comply with a number of Environmental protocols.
