Instrument SpecificationFor Model ST100 Insertion Thermal Mass Flow Meter

A. GeneralThe thermal dispersion type multivariable mass flow meter shall consist of an insertion type flow element.Electronics may be integral or remote mounted. The method of operation shall utilize a varying differentialtemperature signal, generated by a constant power source, between two RTDs. The flow meter shall produceoutput signals linear to the mass flow rate and temperature of the process air or gas. All calibrations shall beperformed on NIST traceable flow stands and be based on measuring the maximum velocity associated with afully developed flow profile. Electronics can store up to five (5) unique calibrations depending upon theapplication. Optional calibration for tab-type flow conditioners shall be available for applications withinadequate straight-run conditions. Flow elements that use a variable power operation principle, or fixed“Delta T” temperature sensing, or that are calibrated to the average velocity, or utilize a non-tab flowconditioner design shall not be considered an equal.
