EC: Daniel 3812 Liquid Ultrasonic Flow Meter

Process control – Flowmeters: Daniel 3812 Liquid Ultrasonic Flow Meter provides high-accuracy measurement for many noncustody transfer applications in the petrochemical, oil, water, and wastewater industries. This is a Control Engineering 2012 Engineers’ Choice award winner.


Daniel 3812 Liquid Ultrasonic Flow Meter. Daniel 3812 Liquid Ultrasonic Flow Meter provides high-accuracy measurement for many noncustody transfer applications in the petrochemical, oil, water, and wastewater industries. This is a Control Engineering 2012 Engineers’ Choice finalist.Emerson’s Daniel 3812 Liquid Ultrasonic Flow Meter with integrated diagnostics package addresses customer needs for not only improved accuracy and repeatability, but also the requirement for cost-efficient flow measurement in noncustody transfer applications. 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.

Daniel 3812 is less sensitive to changes in the flow profile, solids, or entrained air, which results in accurate, stable, and reliable measurement. Operators don’t have to sacrifice accuracy for repeatability. 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.

Within the meter body are four nonwetted, 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 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 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.

A predictive diagnostics package provides an intuitive view of meter health, which allows operators to access real-time process conditions and to address maintenance alarms before they lead to failure. The meter’s Ethernet compatibility enables multiple users to remotely monitor process information. The Smart Wireless THUM adapter allows wireless access to flowmeter diagnostics without the need for any additional wiring.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
