Frequently asked questions
What is fiscal gas measurement, and what equipment does a custody transfer system include?
Fiscal measurement is the determination of the quantity of gas, expressed as volume at reference conditions or as energy, on the basis of which a transaction between seller and buyer is invoiced. A complete system includes the meter, for example ultrasonic or turbine, the pressure and temperature transmitters, the flow computer that applies the corrections from the standards, and the gas composition analysis, performed with a chromatograph. All are calibrated traceably, and the metrological parameters are sealed so that the result can be verified by both parties. The difference between fiscal and process measurement is precisely this traceability and this possibility of audit.
What does a gas pressure regulating and metering station (SRM) consist of?
A pressure regulating and metering station takes gas from the transmission pipeline or the high-pressure network and delivers it to the consumer at the required pressure, measuring it. In the order of flow, it has the filter or separator, the preheater when the pressure drop requires it, the regulating lines with working regulator, monitor and slam-shut valve, the safety valve, the meter with flow computer and, on distribution networks, the odorisation unit. Usually two lines are built, one in service and one standby, so that maintenance work does not interrupt the supply to the consumer.
Why is natural gas odorised, and how is the odorant dosed?
Natural gas has no smell, so a leak would go unnoticed until an explosive mixture formed. An odorant is added, usually an organic sulphur compound, at a concentration that makes the gas perceptible well below the lower explosive limit. Modern units use a dosing pump controlled by the meter's flow signal, so that the dose, expressed in milligrams per cubic metre, remains constant even when the flow varies. The actual value is set by national regulations and by the contract with the network operator, and the concentration in the network is checked periodically by measurements at consumers.
What does API 6A / ISO 10423 mean for a wellhead valve or choke?
API 6A, also adopted as ISO 10423, is the standard that sets out the requirements for wellhead and Christmas tree equipment, that is dimensions, pressure ratings, temperature and material classes, tests and marking. The nameplate shows the rated pressure, the product specification level and the applicable classes. Before ordering, these data are compared with the pressure, temperature and composition of the well fluid, including the presence of hydrogen sulphide, which requires materials conforming to NACE MR0175 / ISO 15156. Spare parts are identified by the markings on the nameplate.
How do I choose between an ultrasonic meter and other types of gas meter?
The ultrasonic meter suits large pipelines and variable flows, because it has no moving parts, produces no significant pressure drop and provides continuous diagnostics. Turbine meters are widespread at medium stations with relatively stable flow, but they require bearing maintenance and are sensitive to pulsation. Diaphragm or rotary meters serve small consumers. The choice takes into account the flow range, pressure, gas cleanliness, space for the straight run and the metrological requirements of the application. For an existing station, the available length is also considered, and it may call for a flow conditioner.
What information do I send for a quotation, and how long does delivery of oil and gas equipment take?
For a correct quotation, send the product code or, if you do not have it, the application data: inlet and outlet pressure, minimum and maximum flow, nominal diameter, type of gas or fluid, temperature, Ex zone and any certification requirements, so that the quotation matches your request. Delivery takes 24–72 h when the item is available locally or at the supplier; equipment and systems made to order arrive, as a rule, in 1–4 weeks, and depending on the brand and the specifications it may take longer.
