Head tank calibrate system, literately, it has a 10 meters high water tank which provide a steady water head, and it is resulting a very steady water flow rate when calibrating. it’s also equipped temperature steady controller.
This system was composed by two systems:
1)Comparative system－compare with our standard flow meters, flow rate is form 5 to 1667 LPM.
headtank
2)Weighting system－it’s a primary calibrate system by weight-flow rate converting, flow rate is from 0.025 to 5 LPM. The smallest uncertainty is 0.5%.
This system was accredited by TAF recently.
