Flow Monitoring in Hazardous Locations

All  of Litre Meter’s VFF flowmeters are certified for use in Hazardous Areas.  They are supplied with certification as standard approved to ATEX, IECEx and CSA US standards.  Normal instrumentation is the Litre Meter FlowPod which can be mounted directly on the meter or remotely. Optionally, the Fluidwell range can be used with IS specification. … Read more

The Base Model, 4 standard meters at better prices

Introducing our ”Base Model” series of VFF meters. The most popular VFF meters are now available in standard configurations at keener prices and shorter delivery times. The Base Model Range These are the LF15, MF30, VFF4 and VFF8 sizes. 1/2″NPT threaded female connections, 316L stainless steel bodies and elastomer seals complete the specification. The internals … Read more

Rotary Piston versus Turbine Flow Meters – Application strengths

We’re often asked why we recommend our VFF Rotary Piston device for chemical injection and, in particular, against the traditional turbine flowmeter.  Here are 8 specific advantages of the VFF over turbine flowmeters: Low Flow The lowest flow measurable by a VFF rotary piston positive displacement flowmeter is two orders lower, especially if the viscosity … Read more

Six Degrees of customisation

Litre Meter supply a range of flow meters for Oil & Gas applications. They specialise in customising a range of flowmeters to meet specific customer requirements. A good example of this is flow meters for subsea use i.e. with the ability to work subsea and transmit a flow signal signal to the surface. The image … Read more

What Flowmeter calibration techniques do Litre Meter use?

Essentially, there are three separate calibration methods that Litre Meter have in-house to calibrate a range of flowmeters.  As the fluids can vary from water to thick oil and the flows range from a few millilitres per hour to 1,000 litres per minute, there are not only three calibration methods but 10 rigs in total, … Read more

Low Flow Calibration – limits

What’s the difference between LF03, LF05 and LF15 in the context of STD, LF and ULF calibrations?

Measuring Sodium Hypochlorite in Hazardous Areas

Sodium Hypochlorite can be difficult to measure as it requires specific wetted materials. Litre Meter have two technologies available for sodium hypochlorite flow measurement.

Flowmeters for Sodium Hypochlorite – Hazardous Area, too

Litre Meter can provide optimum solutions for a wide range of flow rates of Sodium Hypochlorite. Using a variety of materials, a flowmeter can be constructed that handles any specific concentration of NaOCl and provide a display and/or output for measurement and control.

Litre Meter VFF Range

The revamp of the VFF chemical injection flowmeter range in 2015 is described

LITRE METER REVAMPS VFF RANGE

We recently re-designed our 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 … Read more
