RITTER drum-type gas meters are universally applicable for measuring the volume of flowing gases and are particularly effective when measurements demand the highest precision.
The major advantage and the superiority of volumetric Gas Meters (like Drum-type Gas Meters) over other measurement principles, which determine gas volume using secondary measurable variables such as speed, heat capacity, hot-wire resistance or similar, is that the volume is directly measured. That means that the condition and the composition of the gas has no influence on the measurement accuracy.

Correcting factors which take into account gas type, temperature, humidity etc are therefore not necessary. It should be noted that with other, non-volumetric measurement processes, the measurement accuracy given for that process can only be achieved if the correcting factors for the immediate condition of the gas are exactly known.

The possibility of selecting the gas meter material from among 5 different excellent materials (polyvinyl chloride (PVC), polypropylene (PP), polyvinylide fluoride (PVDF), PE-el (polyethylene-electrically conductive) or 1.4571 (refined stainless steel) enables the user individually to meet measurement requirements even in case of highly aggressive gases.
For rugged, industrial applications, robust models with a stainless steel casing and plastic drum (three different materials) are available.
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
The VFF meter is selected for chemical injection service. The fluids are dosed at relatively low flowrates and they are generally viscous in nature. The positive displacement principle of metering provides high accuracy for these difficult measurement conditions. Alternatively, for higher flowrates a precision, positive displacement Helical Screw Flowmeter is used. Typical applications are: Scale inhibitor, Corrosion inhibitor, De- emulsifier, O 2 (Oxygen) Scavenger and Wax inhibitor.
VFF Rotary Meter
• 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 50 bar to 2,068 bar 30,000 psi and higher pressure designs can be provided.
Helical Screw Flowmeter
• Positive displacement meter Œ flowrange to 150 l/min.
• Unaffected by any line size change at flowmeter connections.
• Standard pressure ratings to 1034 bar Œ 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
• 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 0.5 ml/min
• Standard designs to 2,068 bar 30,000 psi at 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 0.01 l/min to 33 l/min for low viscosity fluids
• MM series orifice/by-pass designs from MM12.5, •" to MM300, 12" size for high flowrates
• 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
• Sensor Intrinsically Safe BASEEFA certified EEx ia IIc T5 to CENELEC standards
• Connections are screwed, flange fitting or hub connector types
