Micro Motion Gas Specific Gravity Meters
Micro Motion Gas Specific Gravity Meters use proven Ni-Span-C vibrating cylinder technology to provide fast-response, precision
gas specific gravity measurement over a wide operating range. These meters can be calibrated to directly measure specific gravity,
molecular weight, relative density, and base density; and, can be configured for hydrogen purity, calorific value/BTU and wobbe
index. No additional calculation using temperature and pressure compensation is required. The SGM can be used in applications
such as natural gas custody transfer, fuel gas combustion control and hydrogen purity monitoring.
