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. With its innovative remote transmitter
Promass O 500 maximizes installation flexibility and operational
safety in demanding environments. Heartbeat Technology enables safe
processes.
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
