Adds Micro Motion Coriolis Mass Flow Meters from Emerson
Superior Energy Systems has added Micro Motion Coriolis mass flow meters from to its line of PRO-Vend 1000, 2000 and Dual Hose propane autogas dispensers. The Emerson Process Management technology allows more accurate long-term fuel measurement compared with mechanical meters.
The anti-corrosive, stainless-steel meters help reduce fleet operators’ costs, SES says: “The devices require little to no maintenance compared with mechanical meters, and can be replaced less often since they have no moving parts.”
With mechanical meters, fuel is “given away” due to fuel slippage.
No More ‘Fuel Slippage’
“Mass flow meters virtually eliminate unaccounted fuel that slips through the worn moving parts of mechanical meters,” SES says, noting that some states require that dispensers be taken out of service for fuel slippage issues.
“Mass flow metering technology is heavily used in compressed natural gas dispensers, and is long overdue in the propane autogas market,” SES operations director Jim Bunsey said in a release.
“Our customers, particularly internationally, have requested this technology, and so we’re adding it to several of our top-selling dispensers while maintaining our competitive pricing,” he said.
No Volume Corrections Needed
Mass flow meters work by introducing Coriolis force into the flow stream of a fuel dispenser, then measuring liquid flow by detecting the resulting change in fluid momentum.
“Mass flow meters are ideal for measuring liquefied gases such as autogas due to the fuel’s inherent temperature and pressure fluctuations,” SES says: “By directly measuring the mass flow, no volume corrections are needed to account for fluid variables. This results in a much more reliable, error-free measurement reading.”
SES announced earlier this year that it had earned National Conference of Weights and Measures-NTEP/National Type Evaluation Program certificates for its propane autogas dispensers (F&F, February 19).
