Ultrasonic Flowmeters Help Reduce Drug Production Costs
Titan Enterprises reports that its Atrato and MetraFlow ultrasonic inline flowmeters are used by drug manufacturers to streamline production and reduce costs. These devices measure a liquid’s rate of flow with extraordinary levels of accuracy, helping drug manufacturers control small details that make a big difference during production. Production of pharmaceutical drugs presents difficult ...

Significance of buoyancy in turbulence closure for computational fluid dynamics modelling of ultraviolet disinfection in maturation ponds
Buoyancy-driven turbulent dispersion in a maturation pond is studied using a combination of field measurements and computational fluid dynamics. Modelling flow in maturation ponds requires turbulent closure models because of the large physical size and the need to model on diurnal timescales. Simulation results are shown to be more sensitive to the inclusion of a buoyancy production term ...

Evaluation of CFD model predictions of local dispersion from an area source on a complex industrial site
The CFD model Fluidyn-Panache was configured to model atmospheric transport from an area source. Modelled flow and turbulence were evaluated by comparison with on-site meteorological measurements, whilst atmospheric dispersion was compared with wind tunnel measurements. The results showed that higher rates of vertical and lateral dispersion were modelled than were determined in the wind tunnel, ...

Study of hydraulics and mixing in roof tanks used in intermittent water supply
Roof tanks are common in low and middle income countries, due to the intermittent water supply. Their hydraulic and water mixing behaviour has not been studied. This paper presents the results of a study on mixing and water demand in roof tanks, based on physical and numerical models. Tracer tests were carried out on a real scale transparent wall laboratory model of a roof tank, and a ...

Six top factors to consider when selecting a flow meter
Water utilities rely on accurate and dependable flow measurement for critical process controls. Regulatory agencies also require flow monitoring and reporting, with specific accuracy limits. Flow metering technology is continually improving, and a variety of meter types and styles are available. Each flow meter application is unique, and flow meter selection should not be based on “low ...
