Abstract

Flow rate has a direct influence on the liquid level in any given tank. It is essential to have information on the flow rate of various liquid flows through the pipe with adequate accuracy in the plant to calculate the tank's fluid level. The Computational Fluid Dynamics (CFD) tool is used in modeling and analyzing the setup. The model consists of a level tank with a constant outflow. Inlet to the tank is supplied through a pipe fitted with the orifice type flow meter, reading the inflow rate to the tank. The liquid level in the tank is computed by using the inflow and outflow values. The orifice flow meter is placed on the pipe to measure the flow rate. In this model, simulation readings are extracted for variation in inflow to the liquid level and the effect of parameters like sensors placement, the temperature of the liquid, and density of the liquid. The data is then used to find the liquid level in the tank. The liquid level is calculated for different densities, temperatures, and sensor positions. Inlet velocity and liquid level that are calculated are normalized and plotted versus time. Fluid level characteristics follow the characteristics of inlet velocity.
