Air flow calibrators revolutionize high-grade air flow calibration. Designed to replace the error-prone, inflexible, large-volume piston transducer with a compact, easy-to-use, versatile digital mass flow standard. Whether your requirement is a manual calibration of a simple variable area flow meter or a fully automatic calibration of a mass flow controller, the ideal solution is provided. Combining a reference flow monitor with laminar flow elements, the gas flow calibrator provides true mass flow calibration and traceability without volume-to-volume conversion. quantity. Represents real-time mass flow for ranges of total uncertainty over a year. The air flow calibrator is feature-packed and easy to automate. The system has no moving parts and measures air flow continuously without oscillation from piston stroke. Kits contain everything needed although the modular design allows for simple upgrades and expansions.
