To overcome this problem MACE Flo series instruments include the maximum measurement count feature whereby if the instrument detects a state change i e flow has started or flow has stopped it stays on and takes X number of readings to confirm this situation If all X number of readings meet the criteria for a valid reading as set by peak threshold flow threshold minimum stream activity and stream activity percentage then the reading is accepted and the change of state confirmed If the readings do not all agree that there has been a change of state then the reading is discarded and the current flow state remains That is the unit continues to calculate zero flow or accepts the flow rate as calculated Furthermore the Flo series instrument also checks that the direction of flow has not changed within the X readings For example if there is zero flow and the unit detects a reading of positive flow and another of negative flow then the overall reading is discarded and the unit continues to register a zero flow The number of readings used for the maximum measurement count is configurable by the user Velocity calculation method Pump method Under normal conditions water flow that is provided by a pump is turbulent and contains a vast number of acoustically reflective particles particularly miniature air bubbles that are a result of cavitation events In monitoring sites that are pumped or where low signal strengths are uncommon
