Description

Application

The Promass O is engineered for exceptional accuracy in measuring liquids and gases, even under the highest process pressures, particularly in the oil and gas industry. This sensor is ideally suited for offshore environments, offering strong resistance to stress corrosion cracking. Featuring a compact transmitter, the Promass O 300 provides flexible operation and seamless system integration, with single-side access, a remote display option, and enhanced connectivity. The built-in Heartbeat Technology ensures reliable and safe processes. Its measuring principle remains unaffected by fluid properties such as viscosity and density, making it ideal for applications requiring precise measurements under extreme conditions, including offshore operations.
