The layout is based on the site layout diagram provided by the original customer, with two independent test rooms, 6 workstations for safety testing energy efficiency, and two test rooms with constant temperature and humidity testing structure. The constant temperature and pressure water supply system is located at the back of the room, and the safety testing energy testing share a set of constant temperature and pressure water supply system. Two sets of constant pressure pumps are used for independent constant pressure water supply for each workstation, one of which high pressure constant pressure water supply, suitable for high water pressure testing. Two of the workstations are equipped with 32 thermocouple temperature sensors. The flow collectionstation is 6 workstations (two of which are small flow collection, using brand Yokogawa flow sensors for independent collection) suitable for small flow functional testing. Constant water supply is provided to each workstation through a circulating return pipe. The water outlet is not higher than 80CM above the normal use height, and the lower part of water outlet is the position of the flow sensor for actual flow collection, which effectively improves the accuracy and stability of the flow meter.
