Oil Industry Flowmeters
Litre Meter Flowmeters Application Engineered
Litre Meter was founded in 1975 and is very well recognised and established flowmetering company. All the flowmeters are relatively simple in their primary element design and are extremely reliable. the keynote of our company is excellence in engineering, we are exceptionally flexible and can produce application engineered flowmeters to meet specific needs.
Chemical Injection with Viscous Fluids
Most VFF meters in operation are on chemical injection service. The fluids are dosed at relatively low flow rates and they are generally viscous in nature. The positive displacement principle of metering provides high accuracy for these difficult measurement conditions. Typical applications are: Scale inhibitor, Corrosion inhibitor, De-emulsifier, O2 Scavenger, Biocide, PPD (Pour point depressant), Hydrate inhibitor (LDHI) and Wax inhibitor.
VFF Rotary Meter
The positive displacement principle offers measurement where turbine type meters will not operate. For example a scale inhibitor of 90 cSt viscosity with a flow range of as little as 0.1 l/hr. The meter maintains metering accuracy for the varying viscosity of such a fluid with temperature changes.
Chemically resistant materials of construction.
Standard designs from 40 bar to 4,000 bar (60,000 psi).
Helical Screw Flowmeter
Positive displacement meter - flow range up to 150 l/min.
Unaffected by any line size change at flowmeter connections.
Standard pressure ratings to 1034 bar - higher ratings are available.
Hydraulic Line Monitoring for Well Control Valves & Leak Detection
Flowrates for this application are generally low requiring a suitable capacity flowmeter. A small size VFF Rotary Meter is ideal for this requirement and its Positive Displacement measurement principle provides major advantages for low flow service. VFF and Helical Screw flowmeters have wide rangeability and measure very low flows, which meet the requirements for leak detection service.
VFF Rotary Meter
Allows 'footprinting' of valve actuator movement and confirms opening/closing operation. The VFF Meter provides superior accuracy and:
Superior rangeability than ordinary turbine type meters, which are normally over-sized for the application
Leak detection: from as little as 5 ml/min for common hydraulic fluids
High viscosity fluids are measured from 0.1 ml/min
Standard designs to 2,068 bar (30,000 psi) and higher pressure designs can be provided.
Helical Screw Flowmeter
Leak detection but with high flowrate capability
Chemical Injection & General Metering of Low Viscosity Fluids
Pelton Wheel flowmeters offer exceptionally wide rangeability and low flow rate measurement for low viscosity fluids. Typical applications are methanol, biocide, ethyl-mercaptain and wash water. The LM Series measure low flows in six ranges. These are determined by internal 'jets' which can be interchanged in-situ. VFF Rotary and Helical Screw meters may also be used for low viscosity fluids for some applications.
Pelton Wheel Flowmeters LM and MM Series
LM flowmeters offer low flow rate and wide rangeability from 0.004 l/min to 33 l/min for low viscosity fluids
MM series orifice/by-pass designs from MM12.5, 1/2" to MM300, 12" size for high flow rates
Accurate and repeatable with wide metering range
Chemically resistant materials of construction
Standard designs from 10 bar to 2,068 bar 30,000 psi. Body designs include high pressure screwed, Grayloc hub connections or wafer types for flange fitting. The use of welds is avoided
