AMS Instrumentation & Calibration
offers the ST100 Series thermal mass air/gas flow meter from Fluid Components International. The meter has obtained full certification from the HART Foundation for its hardware and DD files, indicating full compliance with the HART Communication Protocol.
The flow meter was developed in response to discussions with instrument, process and plant engineers, who wanted comprehensive measurement information as well as the flexibility to adapt to future plant and process control technology.
It is available with 4-20 mA analogue, frequency/pulse, alarm relays and additional digital bus communications including Fieldbus, Profibus and Modbus.
The flow meter 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. An optional, patent-pending SpectraCal Gas Equivalency calibration method lets users select and switch between 10 common gases.
Also standard is an on-board data logger with an easily accessible, removable 2-GB micro-SD memory card capable of storing 21 million readings.
