Accurate low flow metering for chemical
injection
UK offshore chemical injection applications frequently specify Litre Meter rotary piston meters for measuring low flows at high pressures: more have been recently supplied to the BP Clair project
Litre Meter has supplied 2 x VFFMF15 and 4 x VFFLF10 rotary piston meters to Italian contractor Bennelli Ravenna as part of the BP Clair project The VFF series meter has been in use since 1989 for a number of UK offshore chemical injection applications where they are specified for their capabilities in measuring low flow and high pressure

Thermal mass flow regulators and mass flowmeters for gases are now among the standard instruments used in industrial laboratory and production processes: these units measure the mass flow directly
Litre Meter are proud to introduce the LMX range
The LMX range of Pelton wheel flow meters offer the low flow performance and reliability of the existing LM/MM range, with increased pressure and temperature rating at a competitive price
Applications for flowrates as low as 0.0004 l/min (0.5 litres/day on high viscosity fluid) and 1.2 l/day on 11cSt have been metered within the offshore oil industry.
These ATEX approved meters exhibit exceptional rangeability with a turndown of 3000:1 for just moderately viscous engine oil and 500:1 for 11cSt.
The rotor size determines the meter flowrange.
The smallest standard stock size offers 0 to 0.25 l/m and the largest up to 45 l/min.
For the BP Clair project pressure was 110 bar, but ratings of 345, 690, 1380 up to 2000 can be specified.
Meter bodies are produced at the Litre Meter manufacturing facility in Aylesbury, Buckinghamshire and fabricated in 316 stainless steel offering good chemical and environmental resistance.
There is also the option for manufacture in other materials such as duplex.
Standard digital display is top mounted and battery operated with a 4-20 mA loop version available.
Litre Meter has recently established agents in Brazil and Norway to supply their VFF series to meet the increase in demand for low flow/high pressure metering capabilities.
