Litre Meter VFF rotary piston positive displacement flowmeters have proven to be the foremost solution for chemical injection flow metering applications. They are able to handle the wide range of flows at pressures from a few bar up to 10,000 and 20,000 psi (690, 1,380 bar) and higher. The FlowPod instrument has been developed after feedback from many clients in the chemical injection arena, focussing on ease-of-use, compactness and functionality.

In many chemical injection applications the VFF is the sole answer because of it’s unique capabilities at the ‘margins of measurement’. This might include super low flow rates and low viscosity or awkward chemical compatibility and material requirements. The standard range of VFF meters, available from 2015, was also designed in response to user feedback. It provides a number of bespoke chemical injection features that are no longer specials. Since then, 80% of meters supplied have been from stock designs as opposed to 20% before. This also means that drawings are immediately available including STEP files, lifting diagrams and parts lists.
Since 2013, as standard, all VFF meters have a URL given on the name plate and a QR code that links to a website with specific calibration certificates, manuals, hydrostatic test certificates and material certificates.
- VFF positive displacement meters can measure accurately at any pressure and with a pulsing pump. The measurement accuracy is unaffected by working pressure or change due to the unique construction.
- VFF positive displacement meters can measure a range of chemicals at extreme low flows such as less than 100 ml per hour and at low or high viscosity. Particle size limits are a generous 40 or 100 microns.
- VFF positive displacement meters can measure a variety of chemicals requiring alternatives to 316L. Titanium rotors are standard with titanium, super duplex and Hastelloy options for body and cap.
- VFF positive displacement meters can be constructed using exotic materials and/or exotic material specifications. Litre Meter have developed their own material specification for 316L, duplex and super duplex. We have built meters from highly specified materials with extensive testing regimes to tight delivery times.
