An Overview of Flow Computers and Their Function
Flow computers are essential components of large scale systems with multiple flows that need to be continuously analyzed and managed. They automate the data collection and data management processes so that operators can get a snapshot of the system status and make decisions quickly.
Flow computers also provide a means to calculate corrected values and interpret data from compensated flow meters. Compensated flow meters are those that need a certain amount of pressure to accurately measure flow rate. If the flow meter does not receive the required pressure, the flow rate reading can vary significantly from the actual flow rate within the pipe.
Uncompensated flow meters, also known as non-compensated flow meters, do not rely on specific pressure values and usually work within a defined pressure range. For applications where pressure is consistent, compensated flow meters work fine. For all other applications where pressure varies within a range, uncompensated flow meters should be used. Regardless, flow computers can collect data from compensated or uncompensated instruments and identify the actual flow rate by performing calculations.
