Mathematical Analysis of the Dynamic Flow Characteristic in a Damping Nozzle for a Pressure Transmitter

P D Howell, A A Lacey, J Vogler and A Vonsild


Abstract

We analyse the flow of a liquid along a pipe and through a small nozzle connecting the pipe to a pressure sensor. The aims are to predict the accuracy with which the pressure in the sensor reflects that in the pipe, and to determine whether or not cavitation occurs in the reservoir.
