Venturi Tubes
Venturi tubes are reliable, easy to use and maintenance-free flow meters. Venturi tubes are particularly well suited to the measurement of clean liquids and gases. Venturi tubes are preferred over other differential pressure flow meters as their design encourages a higher pressure recovery and reduced upstream and downstream pipe requirements. Also, Venturi tubes do not require the use of flow conditioning devices upstream of the high pressure tapping.
