Flexible approach to crude sampling S


tatiflo were approached by a major contractor working in the North Sea who encountered a problem where accurate


sampling for fiscal metering was required across turndown of 8:1 over the well life. The process could accept a maximum pressure drop of just 0.2 bar. Statiflo’s Engineers worked closely with the contractor and end user to develop an inline static mixer which could easily be adapted to achieve a C1/C2 ratio ratio of the distribution of water particles across the pipeline)in line with the requirements of ISO3171 over the complete flow range, without exceeding the maximum acceptable pressure drop.


the flow would need to be through 4-in, then 3-in and finally 2-inNB static mixers. To ensure there were no changes to the installed pipework, Statiflo developed a system using a single 6”NB spool with easily removable 4-in, 3-in and 2-inNB static mixer inserts. Each insert would include Statiflo static mixing elements, designed to fit within a machined seat within the 6-inNB spool. Statiflo received the contract for these and three further Duplex static mixers required within this project. ■

The existing pipework was 6-inNB and Statiflo’s Engineers determined that to meet the requirements


Industrial flowmeters U


K flowmeter specialist Litre Meter has introduced a range of industrial flowmeters from Swiss manufacturer


Vögtlin Instruments. The instruments measure the flow of liquids


and gases in a wide range of industrial and process


applications worldwide. Litre Meter is now able to supply the full Vögtlin range of thermal mass and variable area flowmeters to UK customers. For gas flow measurement applications,


Vögtlin thermal mass flowmeters use heat to measure flow. Heat is introduced to the flow stream and the instrument measures how much heat is dissipated using temperature sensors. The Vögtlin Red-y series has an accuracy of ±1 per cent of full scale and models have a measurement range of between 100 norm millilitres per minute (mln/min) and 5000mln/min. The compact series is battery powered and has an LCD display, manual valve and alarm function. Variable area flowmeters are robust and

customisable. They offer a measuring accuracy of ± 2 per cent to ± 5 per cent, even in long-term operation up to a temperature of up to 100°C. The pressure of a fluid moves an internal float inside a glass tube along a linear scale enabling the flow rate to be calculated.


The Vögtlin product line complements the


range of flowmeters built by Litre Meter in its own premises in Buckingham. The company offers a broad range of metering technologies suitable for virtually every liquid, gas or steam measurement application and has particular expertise in measuring low flow rates. Charles Wemyss of Litre Meter said: “Litre


Meter’s strength has traditionally been in flowmeters for particularly demanding situations, often with meters almost custom-designed and built for particular applications. Vögtlin gives our customers access to an off-the-shelf range of accurate and robust meters which meet the needs of a vast range of industrial and process applications.” ■
