Electronet series Venturi is the second most common differential pressure primary element. It is based on proven technology. It has no moving parts and is suitable for high temperature and pressure applications. Venturi tubes offer advantages including an extremely low pressure loss, a higher durability and a lower chance of catching a sludge media and sediment than other throttle elements. The Venturi tube is mostly used for measurements of flow wherever a minimal loss of pressure is important. The major advantage of the Venturi over orifice plates and flow nozzles is in the area of pressure recovery. Typically unrecovered pressure is in the region of 10 - 30% of measured DP as opposed to 40 - 90% for an orifice plate (depending onbeta ratio).
