Micro Motion High Pressure Coriolis Flow Meters HPC015 and HPC020

Coriolis metering for ultra-high-pressure injection and dispensing

The Micro Motion High Pressure Coriolis (HPC) meter is designed for ultra-high-pressure duty, up to 16,401 psi (1,131 bar) on the largest model. The datasheet names chemical injection in oil and gas and hydrogen dispensing as typical uses. It has no moving parts and needs no special mounting or flow conditioning, and it can be supplied with MVD Direct Connect technology that removes the need for an external transmitter where space and weight are limited.

Technical specifications

Transmitters and installation

HPC meters are offered with MVDSolo, 1500, 1700, 2200, 2400, 2500, 2700, 4200 and 5700 transmitters, giving single or multivariable outputs with milliamp, pulse, dual pulse or digital signals and an integral display. The rupture disk vents process fluid if a tube fails, so the sensor must be oriented and piped so that personnel and equipment are never exposed to the discharge path, and the disk must stay installed to keep the Ex-i certification and IP rating. See the Micro Motion 5700 for an advanced transmitter option.

Temperature and pressure effects are small. The datasheet gives a process temperature effect on mass flow of ±0.0009 percent of maximum flow per °C for HPC015M, N and P, ±0.00175 for HPC015H and ±0.002 for HPC020M and N. There is no process pressure effect on mass flow accuracy up to the maximum pressure rating, and the density pressure effect on the HPC015 is 0.000001 g/cm3 per psi (0.001 kg/m3 per bar).

What to confirm before ordering

• Maximum and normal operating pressure against the model rating, including pressure spikes
• Fluid, flow range and temperature, and whether hydrogen or injection chemical service applies
• Fitting adapter size (9/16 in or 3/8 in) and wetted material (XM-19 or nickel alloy)
• Transmitter, mounting and output type, and hazardous area approval
• Whether the rupture disk should be fitted or omitted

How the Micro Motion HPC works

The fluid flows through tubes that are made to vibrate. The mass flow bends the tubes slightly, and sensors read the twist. The twist gives the mass flow directly, and the tube frequency gives the density. The meter has no moving parts and needs no flow conditioning.

Installation, commissioning and maintenance notes for the Micro Motion HPC

Fit the sensor on the line with the 9/16 inch autoclave connections. Support the pipe so the sensor carries no stress. Connect the transmitter or the Direct Connect electronics. Zero the meter with the flow stopped and the tubes full. Check the zero at each service.
