With data on five British Standard flumes and weirs, and 10 Parshall flumes already in its memory, Liquiflex can easily give single button instantaneous readout of flow, head or total flow.
If the characteristics of your flow channel do not allow for any standard law then the 16 point linearisation facility will enable you to put your requirements into the memory.
