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. With its compact transmitter Promass O 300 offers high flexibility in terms of operation and system integration: access from one side, remote display and improved connectivity options. 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
Device properties
Measuring tube in 25Cr Duplex, 1.4410 (UNS S32750)
Process pressure up to PN 250 (Class 1500)
Nominal diameter: DN 80 to 250 (3 to 10")
Compact dual-compartment housing with up to 3 I/Os
Backlit display with touch control and WLAN access
Remote display available
Benefits
Maximum safety – highest resistance to stress corrosion cracking
