WebDifferential Pressure Flowmeters. Differential pressure flowmeters are also known as Head type flowmeters. They are the most prevalent type of flowmeters in use today. It has been projected that more than 50 percent of all liquid flow measurement applications make use of this type of unit. The basic Working principle of differential pressure ... WebConnections that are not flush and/or have rough edges have different head losses depending on direction of flow in the connecting piping. This causes buildup or reduction of head in stilling wells compared to the actual head in the measurement device. The size of the stilling well depends on the method used to measure the head.
