Flow Cart: Flow Through Measurement Devices and Pumping System

Equipment Description

The FLPS (Flow Level Pressure System) consists of a portable rack with a main control panel and data logger, various flow meters, level & pressure instruments, piping, tanks and circulation pump. There are two large collecting tanks found below the cart. Two are needed depending on the orientation we are working in. During this experiment, we will manipulate the opening & closing of valves to achieve a certain orientation of flow. This is done to see any changes in the system when there is flow through specific equipment.

This lab is conducted in WB25A (Fluid Mechanics room), where other fluid mechanics experiments will be conducted, so make sure to be wary of other experiments.

4. Wait until green LED lamp goes out. Then remove Flash Drive. Note: The green lamp stays lit for a bit longer than it takes to copy the data, but please be patient and wait for it to go out before removing the Flash Drive or the data file may be corrupted or incomplete.

5. After the data is retrieved, turn the main switch to OFF. The POWER ON light should turn off as well.

6. Unplug the cable from the power source
