The Micro Motion HPC020M is a precision-engineered 1/6-inch (DN3) Coriolis sensor designed to meet the extreme demands of the hydrogen economy. Capable of managing an extraordinary 12,168 psi (839 BAR) maximum operating pressure, this meter provides the accurate repeatable flow measurement required for high-stakes, high-pressure gas dispensing environments.
In the world of high-pressure gas, safety and precision are non-negotiable. The HPC020M delivers the best real-world Coriolis performance at a maximum operating pressure of 12,168 psi (839 BAR). This robust measurement solution is a single-device powerhouse, capable of providing reliable mass flow, volume flow, density, and temperature measurement simultaneously.
The HPC020M is the global benchmark for hydrogen gas applications, specifically tailored for 350 bar and 700 bar LDV/MDV/HDV refueling stations. Its compact design allows it to fit seamlessly into modern dispenser cabinets where space is limited, ensuring high-speed, high-accuracy filling for everything from light-duty vehicles to heavy-duty trucks.
Hydrogen molecules are notoriously difficult to contain at high pressures. The HPC020M utilizes an XM-19 stainless steel wetted pathway, which is specifically resistant to hydrogen embrittlement. This advanced metallurgy ensures the meter maintains its structural integrity and long-term reliability without the risk of hydrogen-induced cracking, which is common in lesser 316L-only sensors.
Maximize your station's uptime with integrated Smart Meter Verification (SMV). This technology allows operators to perform a comprehensive system integrity check without the need to pull the meter out of service. In a high-pressure 700 bar environment, being able to verify calibration and sensor health in minutes—rather than days—is a critical operational advantage.

To accommodate any installation requirement, the HPC020M offers versatile connectivity. You can choose from a two-wire, direct-connect architecture (where no transmitter is needed) or pair the sensor with the high-performance 5700 transmitter for advanced data logging and historian capabilities.
By design, the HPC020M has no moving parts to wear or replace, drastically reducing the need for routine maintenance compared to mechanical meters. This solid-state design is what enables its superior performance in high-vibration dispensing environments.
Q1: Can the Micro Motion HPC020M handle 700 bar hydrogen refueling?
A: Yes. The HPC020M is specifically designed for ultra-high pressure gas dispensing, with a maximum operating pressure of 12,168 psi (839 BAR), making it the industry standard for both 350 bar and 700 bar hydrogen applications.
Q2: What makes XM-19 stainless steel better for hydrogen applications?
A: XM-19 provides superior yield strength and, most importantly, extreme resistance to hydrogen embrittlement. This ensures the wetted pathway remains safe and reliable under high-pressure hydrogen exposure, where standard 316L might fail.
Q3: Does the HPC020M require a separate transmitter for operation?
A: No, the HPC020M offers a "direct-connect" option, allowing the sensor to communicate directly with your control system via a two-wire connection, though it can also be paired with advanced transmitters like the 5700 series.
