Emerson Expands Ultrasonic Meter Family to Provide High-Accuracy Liquid Measurement for Non-Custody Transfer Applications

High performance Daniel(TM) 3812 Liquid Ultrasonic Flow Meter with integrated diagnostics package provides accurate flow measurement for a wide spectrum of applications

HOUSTON, TEXAS - Emerson Process Management announces the new Daniel(TM) 3812 Liquid Ultrasonic Flow Meter. Designed for reliable measurement, minimal maintenance and ease of operation, this meter is ideal for many applications in the petrochemical, oil, water and wastewater industries.

Innovative electronics combined with advanced digital signal processing make the Daniel 3812 Ultrasonic Flow Meter less sensitive to changes in the flow profile, solids or entrained air, which results in accurate, stable and reliable measurement. This meter can be used to measure liquid products with a high accuracy of ±0.3% and repeatability of ±0.1% due to sophisticated algorithms and the configuration of its measuring ultrasonic paths.

The 3812 utilizes two mid-radius, parallel-plane measurement paths to reduce the influence of flow disturbances and offers all the advantages of transit time and inline ultrasonic flow meters. Ultrasonic flow measurement is independent of conductivity, temperature, density and pressure.

Within the meter body are four non-wetted, intrinsically safe transducers that allow the meter to maintain high accuracy over widely varying flow conditions. These transducers are field replaceable without the need to empty or depressurize the meter, reducing maintenance costs and increasing uptime. The unobstructed ultrasonic flow tube with smooth surface finish inhibits material build-up. This combined with no internal moving parts to wear or drift provides for low pressure drop, increased energy savings, and many years of maintenance free service.

This full bore ultrasonic meter is easy to install and operate. Additional arrangements such as filters, flow strainers, supports, grounding or isolation against vibrations are not necessary. The results are minimal maintenance and substantial savings in cost of ownership.

"Emerson has pioneered ultrasonic flow metering for over 25 years," said Peter Syrnyk, vice president of engineering at Emerson Process Management, Daniel. "Today, we continue to develop and perfect a wide range of ultrasonic flow meters for liquid and gas measurement. The introduction of the 3812 Liquid Ultrasonic Meter addresses customer needs for not only improved accuracy and repeatability, but also the requirement for cost efficient flow metering."

An integrated, predictive diagnostics package provides an intuitive view of meter health and status, allows operators access to real-time process conditions and address maintenance alarms before they lead to failure. Advanced diagnostics continuously perform measurement reliability checks and calibrate the time measurement. The meter's Ethernet compatibility enables multiple users to remotely monitor and verify process information. The Smart Wireless THUM adapter allows wireless access to flow meter diagnostics without the need for any additional wiring.

Daniel liquid and gas ultrasonic meters are part of Emerson's broad range of intelligent, digital field devices that power the PlantWeb® digital plant architecture. Cost savings, enhanced safety, and environmental compliance are achieved when ultrasonic flow meters are integrated into the PlantWeb architecture.
