Field of application
Promass O is designed for premium accuracy of liquids and gases at the highest process pressures in the oil and gas industry. The sensor is fully suitable for offshore conditions and resistant to stress corrosion cracking. Promass O 100 delivers full performance on the smallest footprint with its ultra-compact transmitter and thus enables seamless system integration. Heartbeat Technology ensures process safety at all times.
Measuring principle operates independently of physical fluid properties such as viscosity or density
For premium accuracy at highest process pressures, fully suitable for offshore conditions
