LITRE METER REVAMPS VFF RANGE

Litre Meter has re-designed its popular VFF (Viscous Fluid Flowmeter) range of positive displacement flowmeters. The innovations in VFF technology make it ideal for bespoke flow measurement.

Innovations include a new compact size and design with reduced weight using high strength material specifications for high pressure applications. The new range of meters is suitable for low and high viscosity liquids at pressure ratings from 414 bar right up to 4,000 bar (60,000 psi). The range covers the measurement of fluids from 0.3 centistokes (cSt) to 100,000 cSt and flow rates of 0.0008 l/hr to 16,200 l/hr.

Charles Wemyss, CEO of Litre Meter, said: “Litre Meter has 40 years’ experience in successfully designing and manufacturing bespoke flowmeters for extreme environments for the most demanding industries and applications.

“The VFF series developed by Litre Meter has been distilled into one series to meet the specific requirements of chemical injection flowmetering. The new 2015 VFF range uses the same ultra-reliable rotary/oscillating piston technology that Litre Meter has developed and refined over the past 30 years. With one moving part the flow meter is a robust and low maintenance component within a chemical injection system.”

The VFF range has a wide of standard options so Litre Meter can quickly respond to fulfill most chemical injection enquiries. A full drawing package is available detailing every option in either PDF or STEP formats.

Specifying the right meter for a system is now even easier to specify with a new VFF meter software, a step-by-step builder that takes the user through all the meter options available. When the meter has been selected the user can search the Litre Meter database of over 400 general arrangements and parts listing drawings. For more details the user can browse 3D STEP files for the correct meter to download and insert into the skid assembly.

Meters are constructed from 316L stainless steel, Duplex Super Duplex, titanium and 6Mo. Other materials are available on request. Standard connections include NPT, Autoclave, ANSI flanges, Grayloc hubs, Galperti hubs and Techlok hubs. Two wire Exia and 2/4 wire Exd versions are available and 4-20mA, HART7 communications is standard with new pickup sensor capabilities.

Other innovations in the 2015 VFF range include a new rotatable and positionable Exd approved display union, new sensing options with increased reliability, reverse flow detection and increased resolution.

Charles Wemyss added: “We are excited about the new range. The new compact and lightweight design has been developed specifically for integration within chemical injection skids. Its footprint is further reduced because positive displacement flowmeters don’t require straight lengths of pipe in the system before or after the meter.

“We have also responded to industry demands with regard to lifting requirements for offshore by adding lifting eyes manufactured from certified forged material to every meter that weighs 16 kg or more.”
