The In-situ calibration system

The easily-installed VeriCal in-situ calibration solution from AMS Instrumentation & Calibration can validate performance onsite in minutes and assist with compliance with ISO and local regulations.

The new system allows for speedy verification of flow meter calibration without removing the meter from the pipe or process, and makes it easy to meet process validation more effectively.

The system is available for the revolutionary ST100 Series Flow Meter, which sets a new industry benchmark in process and plant air/gas flow measurement instrumentation, offering some of the most feature-rich and function-rich electronics available today. The ST100’s flow sensing performance delivers increased adaptability and value to meet plant gas flow measurement applications.

Should a plant’s needs change over time, the ST100 Flow Meter adapts as necessary with a plug-in card replacement that can be changed by plant technicians in the field.

The ST100’s unique graphical, multi-variable, backlit LCD display/readout provides the industry’s most comprehensive information, with continuous display of all process measurements and alarm status, and the ability to interrogate for service diagnostics. The user-friendly ST100 stores up to five unique calibration groups to accommodate broad flow ranges, differing mixtures of the same gas and multiple gases, and obtains up to 1000:1 turndown.

The ST100 is the first thermal flow meter to offer three different types of flow sensors to best match user applications. The fast-response FPC-style features an integral flow conditioner and protective shroud optimised for compressed air and clean gas applications. For wet or dirty gases, or erratic flows, the unshrouded S-style facilitates easy cleaning and provides a smoothed response. The fast-response, general purpose FP-style features a protective shroud and is the sensor used with FCI’s VeriCal in-situ calibration option.

The ST100 Series is comprised of two core model families: ST and STP. ST meters measure both mass flow and temperature, and the exclusive STP family adds a third parameter-pressure-making the ST100 the world’s first triple-variable thermal flow meter. Both families include single-point and dual-element models as configurations outfitted with FCI’s exclusive in-situ calibration option, VeriCal.

The ST100 can be calibrated to measure any process gas. The basic insertion style air/gas meter features a thermal flow sensing element that measures flow from 0.07 network measurement policy system (NMPS) to 305 NMPS.

Designed for rugged industrial processes and plants, ST100 Flow Meters include service up to 454 degrees celsius and are available with both integral and remote 300 meters electronics versions. The ST100 is agency approved for hazardous environments, and instrument approvals include: FM and FMc: Class 1, Division 1, hazardous locations, Groups B, C, D, E, F, G; ATEX and IECEx: Zone 1, II 2 GD Ex d IIC T4.
