Ultrasonic flowmeter line grows for general applications

High-performance Daniel flowmeters from Emerson Process Management integrate diagnostics with high-accuracy measurements.


High-performance Daniel flowmeters from Emerson Process Management integrate diagnostics with high-accuracy measurements.Emerson Process Management has announced its new Daniel 3812 ultrasonic flowmeter for liquids. 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.

The company says that using 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. This 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 flow tube inhibits material build-up and a moving part free design minimizes maintenance and pressure drop.

An integrated, predictive diagnostics package provides an intuitive view of meter health and status, allowing 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 monitor and verify process information remotely.
