Tackling Low Flow Cutoff

 

Steam system operators may find themselves paying a steep price if product passes through a meter but doesn’t get measured. Commonly known as low flow cutoff, these losses typically happen because of a flow meter’s turndown ratio, which determines how wide a flow spectrum is able to be measured. If low flow cutoff is a risk in a steam system, operators should be aware of these risks, which include the possibility for missed revenue, erratic flows, and system overdesign.

Let’s take missed revenue, for instance. When an engineer is writing steam meter specifications, the focus is often on the potential maximum flow, even if a system is unable to produce such numbers. The engineer may choose to avoid a flow that’s too low, even if the option is wiser. The lack of metering at the lower end of production may result in a missed opportunity and therefore missed revenue.

Vortex meters have a shredder bar mounted across the diameter of a pipe which allows for low measurement flow. These meters are commonly used in measuring steam and they are also effective for higher flows.

Accurately Measure Fluid Density and Mass Flow with the Badger Coriolis RCT1000

The Badger Coriolis RCT1000 Flow Meter uses a measurement of fluid density and mass flow to identify flow rate, delivering an exceptional degree of accuracy. For homogenous fluids comprised of a pair of components such as sugar and water, the RCT1000 Badger Coriolis system can derive the component’s concentration and mass based on fluid properties … Continued
