Sierra   Litre Meter have manufactured the LM and MM range of pelton wheel turbine flowmeters since 1975. The VFF range of rotary piston positive displacement meters joined the line-up in 1985. Litre Meter specialise in low flow measurement. Many of the meters are customised to customers precise requirments particularly in the field of Oil & Gas.
