New calibration system for flow meters

Jon Lawson

The time-consuming and costly task of traditional flow meter calibrations, which requires shutting down the line, pulling the meter, installing a spare and paying a lab fee, is no longer a pain with the innovative VeriCal In-Situ Calibration Verification System.

This industry-unique calibration verification system reduces flow meter operating costs in flare gas applications aboard offshore platforms, and at land-based oil/gas facilities and in petrochemical plants.

The system is designed to meet 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 (GHG).

Setting a new industry benchmark in process and plant air/gas flow measurement, the ST100 Series Air/Gas Flow Meter offers the most feature-rich and function-rich electronics available. The ST100 meter’s performance delivers unsurpassed adaptability and value to meet plant gas flow measurement applications for today and tomorrow.

With a unique graphical, multivariable, backlit LCD display/readout, the ST100 meter brings new meaning to the term 'process information'. It provides continuous display of all process measurements and alarm status, and the ability to interrogate for service diagnostics.

The easy-to-use ST100 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. Also standard is an on-board data logger with an easily accessible, removable micro-SD memory card capable of storing 40 million readings.
