The test setup of this complex, located at the company's office, has been designed and implemented to measure and verify the accuracy of meters. This setup includes the piping system, pump, hydraulic accumulator, rotameter, water storage tanks, accurate scale, electric shut-off valves, pressure and temperature sensors, and data collection and control boards. The most up-to-date standards are included in the design of this setup and the uncertainties of the calculation are kept to a minimum. In practice, the setup has the ability to test three different types of meters.
