Flow meter offers stability for demanding hydrogen applications

15 September 2020

Emerson has introduced a new Micro Motion Coriolis flow meter designed for high-pressure hydrogen dispensing and chemical injection applications where measurement accuracy and safety are essential.

The Micro Motion Coriolis HPC015 flow meter is capable of a flow accuracy margin of 0.5% for gas and 0.1% for liquid mass flow measurement. The meter performs under wide pressure and temperature fluctuations, ensuring security and reliability, while onboard diagnostic tools eliminate the need for pre-inspections or interim maintenance checks.

One of the main application uses for the HPC015 in accurately measuring the flow of hydrogen gas is to effectively manage costs in large-scale custody transfer applications, such as public transportation systems, where hydrogen fuels are used to power hybrid bus engines.

A second, significant market is in other high-pressure applications such as injecting methanol, corrosion inhibitors and other chemicals downhole at high pressure; an application that poses particular challenges. The HPC015 is designed to accurately and reliably dose chemicals at pressures up to 1,060 bar to ensure pipeline integrity and avoid events like plugging, which can halt production.
