The Rosemount 3051CFA Annubar Flow meter combines the proven 3051C pressure transmitter and the latest primary element technology:
Better measurement begins by selecting the best flow technology for each application. Annubar® technology has been specified for over 35 years in applications requiring performance, flexibility, reliability and lower total cost of ownership. The innovative technology of the Annubar sensors offers more advantages that save time and money.
Multivariable capabilities allow for real time fully compensated mass and energy flow. The 3051CFA minimizes permanent pressure loss and saves energy with annubar technology. It reduces straight pipe requirements to two diameters upstream and downstream from flow disturbances with conditioning orifice plate technology. It improves accuracy and repeatability in small line sizes with a integral orifice plate technology.
Please consider these optional accessories.
This product can be used in the following applications:
The Background: Our customer is an oil refinery that is capturing and utilizing flammable gases from their flare stacks. They seek a means to accurately measure the amount of gas they recover.
The Problem: Flare stacks are used to burn-off flammable gases produced while refining crude oil. Our customer is recovering this gas for other uses. The gas is transported through a 2-inch line at flow rates of up to 4MMSCFD. The high flow makes it difficult to get an accurate measurement on the amount of gas travelling through the pipe.
The Solution: We recommended a Rosemount 3051CFA Annubar flow meter which uses differential pressure measurements capable of accurately measuring real-time mass and energy flow measurements in high flow applications. The 3051CFA is also available with a range of hazardous area approvals making it compatible for use with flammable gases.
The Background: Our customer is a power plant that uses seawater for cooling. They seek a means of measuring the flow of that seawater to ensure there is enough to meet their cooling requirements.
The Problem: This power plant uses steam turbines to generate electricity. A lot of the heat used to create the steam which drives the turbines cannot be converted into energy and must be removed to prevent expensive equipment from overheating which could lead to failure or expensive repairs. This plant uses a 72-inch pipe to bring seawater into the plant to remove the waste heat and they need to monitor the flow to ensure the flow rate is capable of meeting their cooling needs. A primary concern for the customer is the size of the pipe and the cost of installing the flow meter.
The Solution: We recommended the Rosemount 3051CFA Annubar flow meter, a full integrated differential pressure flow meter with reduced straight pipe requirements making it easy to install. Unlike many types of flow meters, the 3051CFA can be scaled for large pipe diameters at a reasonable cost.
