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

blob 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.

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.

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.
