High-Pressure Flow Measurement for a Major NGL Processing Project

High pressure retractable averaging pitot tube assembly prepared in the workshop

Oil & Gas

Project overview

McMenon supplied 10 McMenon Averaging Pitot Tubes for a major natural gas liquids (NGL) processing project in Saudi Arabia.

The project included NGL fractionation, utilities, storage and export facilities, requiring reliable flow measurement solutions across a range of process applications.

The order comprised 1" Averaging Pitot Tubes for line sizes ranging from 18" to 56", providing a robust flow measurement solution for large-diameter process lines.

01 / The challenge

The Challenge

The project required a flow measurement solution capable of operating within high-pressure steam applications and across a range of large line sizes.

The instruments needed to provide reliable measurement while also allowing practical access for operation and maintenance. With the Averaging Pitot Tubes installed on lines ranging from 18" to 56", the solution needed to accommodate the requirements of large process systems while providing a suitable means of isolation and retraction.

The application also required measurement capability for both differential pressure and temperature, supporting comprehensive process measurement.

02 / McMenon's solution

McMenon's Solution

McMenon supplied 10 FPD350 H7 Series High Pressure Retractable Averaging Pitot Tubes, designed specifically for the application.

The 1" Averaging Pitot Tubes feature a dual-grade 316/316L Stainless Steel probe with a 2" Carbon Steel process connection. The gear-operated retractable assembly provides practical operation and maintenance, while a flanged Stainless Steel gate isolation valve provides isolation of the instrument.

The units are designed for connection to remote-mounted transmitters using tapping gate valves and incorporate an integrated temperature element, allowing the instruments to measure both differential pressure and temperature.

The solution was supplied for steam flow measurement across line sizes ranging from 18" to 56".
