Emerson extends the operating range of Daniel® liquid ultrasonic meters to deliver accurate flow measurement for heated crude oil refining applications

New high temperature and high viscosity transducers make the Daniel® ultrasonic flow meter ideal for a wide variety of challenging refining applications

Emerson Process Management has launched new high temperature and high viscosity transducers for its Daniel® Model 3804 liquid ultrasonic flow meter. The high temperature transducers are designed for use from -50°C to +150°C and the high viscosity transducers extend the viscosity range of the Model 3804 up to 1,000 centistokes (cSt) with Reynolds numbers above 10,000, making it an ideal choice for a wide variety of challenging crude oil refining applications.

The highly accurate Daniel Model 3804 liquid ultrasonic flow meter is already the bedrock of tightly regulated custody transfer measurement applications, allocation measurement, and check metering applications in areas such as offshore platforms, crude and refined product pipelines, and marketing terminals. The addition of high temperature and high viscosity transducers will allow users the possibility of employing Daniel Model 3804 ultrasonic meters across a wide range of additional applications such as heavy vacuum oil, naphtha, and kerosene.

The high performance Daniel liquid ultrasonic meter has four ultrasonic paths in two different planes. Within the meter body are eight fully integrated, wetted ultrasonic transducers forming four crossed paths which allow measurement of cross-flow and other flow phenomena. In high temperature applications, the signal processing transmitter is remote mounted from the transducers.

The absence of obstructions or moving parts in the meter ensures no wear or pressure loss, reducing pumping requirements and generating significant energy savings. The placement of transducers at the pipe internal wall, outside the active flow, reduces the chance for localised flow disturbances, dirt build up, erosion on transducer faces, and hydrate build up in low dewpoint applications.
An advanced operation and predictive intelligence package allows users access to real-time diagnostics to detect flow disturbances that may affect measurement, in addition to addressing maintenance alarms before they lead to flow upsets. The need for periodic calibration is also reduced, drastically cutting cost for on-site proving and procedures, resulting in considerable cost savings in both capital and operation expenditure.
