Mustang® Liquid Sample Pump

The Mustang® Liquid Sample Pump (MLSP®) enhances Analytically and repeatability of measurements of Natural Gas Liquids (NGL) extracted from a pipeline by a sample probe during sample analysis processing utilizing a metering pump up-stream of the sample conditioning equipment. The Mustang Liquid Sample Pump also reduces lag time of the pressurized fluid prior to introduction to the sample conditioning equipment. The system generates sufficient residual pressure to offset and overcome the takeoff vacuum (suction pressure) to promote unfiltered bypass flow for fluid reinjection into the pipeline.

The Mustang Liquid Sample Pump achieves accurate and repeatable measurements usable for process control for NGL product quality assurance and for energy audits, particularly, in the case of custody transfer operations involving storage or transmission vessels.
