Flow Meters New Flow Meter Delivers Accuracy, Stability for Demanding Hydrogen Applications
With an available gas flow accuracy rating of 0.5 % and pressures up to 1,060 bar, the Micro Motion HPC015 from Emerson is ideal for high-pressure hydrogen dispensing.
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, a significant improvement over existing meters, states the company.
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, saving time and money, adds the firm.
The demand for hydrogen, an abundant and renewable energy source, is growing due to its use in fuel cells for low-emission vehicles, fertilisers, glass and metal production, as well as the energy sector. Hydrogen is stored at very high pressure – usually at around 963 bar (13,960 psi) – which creates challenges to find equipment to aid in producing, storing and dispensing the gas safely and effectively.
The new flow meter is an extremely accurate, safe and reliable solution to measure flow at high pressures. It was designed specifically to meet the challenges that the customers face in the hydrogen fuel and chemical injection spaces, mentions the firm.
One of the main application uses for the flow meter 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 for the flow meter 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 new flow meter is designed to accurately and reliably dose chemicals at pressures up to 1,060 bar (15,374 psi) to ensure pipeline integrity and avoid events like plugging, which can halt production, opines the company.
In addition to safety concerns, offshore platforms cannot afford to stand idle while waiting for a service call to troubleshoot an instrumentation problem, which in many instances requires an onsite visit by a technician. Space is at a premium on offshore platforms, which makes the small footprint of the flow meter ideally suited, and when combined with the Smart Meter Verification capability of the flow meter, a facility can run meter diagnostics and meet regulatory standards without needing to remove the meter from the process line.
The new flow meter is offered in three pressure tiers – 482 bar (6,991 psi), 963 bar (13,960 psi), and 1,060 bar (15,374 psi), which offers added flexibility to setting the correct pressure range for each application.
