Fluid Components has announced that its Model GF90 flare-gas flowmeter for use in offshore rigs now complies with the US Minerals Management Service (MMS) mandate.

A recently enacted US MMS mandate per final rule, 30 CFR Part 250, Subpart K, Section 250, stipulates that all domestic US offshore rigs processing more than an average 2,000 bopd must install flare-/vent-gas flowmeters.

Existing customers and others affected by the mandate can utilise the company’s special toll-free MMS regulation hotline that is now available to answer flare flowmeter questions.

The hotline will be answered by the FCI Flow Meter Applications Group, which includes specialists in flare- and vent-gas flow measurement.

After reviewing the new MMS regulation, engineers at Fluid Components have determined that the advanced GF90 flare-gas flowmeter complies with its specifications and is well suited to provide a low-cost and effective solution for offshore flare- and vent-gas flow measurement.

The GF90 is claimed to solve the problem of measuring widely varying flare-gas flows that can range from very low-flow leakage rates to upset event flows at very high-flow rates.

The instrument can deliver accurate flow measurement to as low as 0.25 SFPS to as high as 1600 SFPS ([0.08 NMPS to 487.7 NMPS).

Capable of storing flow calibrations for up to three ranges and linking them, the GF90 can achieve a turndown ratio of up to 1,000:1.

It is available for service in a range of application conditions, including temperature service from -100F to +850F (-73C to +454C) and pressures of up to 1,000psig (69bar[g]).

The GF90 is an insertion-style flowmeter that provides low installation costs, according to the company.

Its small size also means it is easily transported out to, and moved about on, offshore rigs.

The GF90’s transmitter features two independent, field-programmable, analogue signal outputs of 4-20mA, which can be assigned to any combination of flow and/or temperature.

Digital bus communications are available optionally.

It also includes dual alarm points with 2A relay outputs, which are user programmable to alarm at high, low or windowed and which can be assigned to flow and/or temperature readings.

In addition, the GF90 is available with the company’s patented Verical in-situ calibration verification system.

This optional configuration includes a specially plumbed flow sensor, added bench-marking calibrations and a portable flow/pressure regulator kit.

The system enables the user verification of the flowmeter’s calibration on site and while still installed within the pipe.

This feature can save money by avoiding unnecessary meter extraction and recalibration services and meets the regulating agency’s preferred in-situ methodology.

A Nema Type 4X, IP66-rated transmitter enclosure is standard.

Optional Class I and II, Division 1 and 2, Groups B, C, D, E, F and G (EEx d IIC) transmitter enclosures and stainless-steel enclosures as required by some offshore rigs are also available with agency approvals for Factory Mutual Research, Atex, CSA, GOST/RTN, IEC, CPA and Nepsi.
