hi every one
what is the most important parameter to test and verify when commisioning chilled water system
what is the most pratical way measuring the flow in each loop?

RE: chilled water system tests
Most practical way of cintinuously measuring loop flow is with a flow meter. Measuring differential pressure drop would be as important, or even more so, as it would go along with factory equipment safety interlock. If commissioning, the easiest way is to ask the TAB subcontractor.
RE: chilled water system tests
what type of flow meter(s) has to be installed?
is it common pracice to measure the flow to each fan coil unit?

For flow measurement, the balancer should set flow to design values at each balancing valve. For commissioning, you should spot check flow by running pumps at full speed (forcing open some loads), recording DP across pumps, and verifying flow approximates what is shown on the pump curves.
