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. Robust high-pressure flowmeter, as remote version with up to 4 I/Os. For premium accuracy at highest process pressures, fully suitable for offshore conditions.
