The Neptune TRU/FLO Compound water meter is an excellent choice for situations in which a wide range of flow occurs.  When larger supply lines are needed to meet the demand of high volume water users, a larger water meter is needed.  What sometimes gets overlooked is the low flow part of the equation.  Larger turbine water meters typically do not register low flow accurately, so much of the low flow is missed.  The compound water meter solves this problem by integrating two separate meters into one meter, so that both high volume and low volume water use are registered.  The TRU/FLO series meets or exceeds accuracy requirements set by the AWWA C702 standard.
