Stop pulling meters out for calibration verification with VeriCal system for FCI ST100 air/gas flow m

AMS Instrumentation and Calibration presents an efficient solution for oil
and gas engineers responsible for performing routine flow meter calibration
verifications on offshore platforms or any difficult-to-access production

Typically, these calibration verifications require the engineers to shut
down the line, pull out the flow meter, install a spare, return the meter to
the manufacturer or a calibration lab for testing and then have it shipped back
for re-installation, resulting in a costly, difficult and time-consuming
process. These problems can now be eliminated by using the VeriCal in-situ
calibration verification system with the ST100 Series thermal mass flow meters from
Fluid Components International (FCI). This unique system for the oil and gas
industry reduces flow meter operating costs in flare gas applications aboard offshore
platforms, at land-based oil/gas facilities and in petrochemical plants.

Designed for regulatory compliance, the ST100 flow meter with the
VeriCal in-situ calibration system meets the US Minerals Management Service
(MMS) Rule, 30 CFR Part 250, Subpart K, Section 250, stipulating that all
domestic US offshore rigs processing more than an average of 2000 bopd must
install flare/vent gas flow meters. These regulations are intended to protect
the environment through the monitoring of greenhouse gases.

The VeriCal in-situ calibration system verifies ST100 flow meter calibration
in minutes without the need to remove the meter from the pipe or process to
meet MMS regulations. The ST100 Series flow meter offers feature-rich and
function-rich electronics with its performance delivering excellent
adaptability and value to meet plant gas flow measurement applications now and
in the future.

The ST100 addresses a broad spectrum of requirements including 4-20 mA
analogue, frequency/pulse, alarm relays or digital bus communications such as
HART, Fieldbus, Profibus or Modbus. Should a plant’s needs change over time or
an upgrade is needed, the ST100 flow meter adapts as necessary with a plug-in
card replacement that can be changed out by plant technicians in the field.

Key features of ST100 flow meters include unique graphical,
multivariable, backlit LCD display/readout providing comprehensive information
with continuous display of all process measurements and alarm status, and the
ability to interrogate for service diagnostics; ease of use with ability to store
up to five unique calibration groups to accommodate broad flow ranges and
differing mixtures of the same gas and multiple gases, obtaining up to 1000:1
turndown; and on-board data logger with easily accessible, removable 2GB
micro-SD memory card capable of storing 21 million readings provided as standard.

Oil and gas engineers can choose from two multi-variable core model
families – the ST and STP families. ST meters measure both mass flow and
temperature, while the 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.

The ST100 can be calibrated to measure virtually any process gas,
including wet gas, mixed gases and dirty gases. The basic insertion style
air/gas meter features a thermal flow sensing element that measures flow from
0.25 to 1000 SFPS (0.07 NMPS to 305 NMPS) with accuracy of ±0.75 percent of
reading, ±0.5 percent of full scale.

Designed for rugged industrial processes and plants, ST100 flow meters include
service up to 850¡F (454¡C) and are available with both integral and remote (up
to 1000 feet or 300 metres) electronics versions. The ST100 is agency approved
for hazardous environments, including the entire instrument, the transmitter
and the rugged, NEMA 4X/IP67 rated enclosure. Instrument approvals in addition
to SIL-1 include ATEX, IECEx, FM and FMc.
