The CALDON LEFM 280Ci Ultrasonic Flow Meter can be used on crude oils and refined products in single- or multi-product pipelines. For maximum performance it is preferred to operate at Reynolds numbers larger than 10,000. For application with lower Reynolds numbers please contact our specialists for a review of your application (see also CALDON LEFM 280CiRN ultrasonic flowmeter).
The eight chordal path design of our CALDON LEFM 280Ci Flow Meter resists installation errors better than any other ultrasonic flowmeters. The cross-plane acoustic paths make the meter immune to the effects of swirl and eliminate the need for an upstream flow conditioner. The effects of swirl on the two paths in each individual chordal plane are equal and opposite to each other, any effects from swirl are cancelled out.
This flow meter's design also minimizes the requirement for upstream/downstream pipe runs. The elimination of a flow conditioner and the need for shorter lengths of upstream pipe reduce the installed cost for the CALDON LEFM 280Ci Flow Meter. This also results in lower overall pressure loss, which equates to annual savings in pumping costs.
