SMERI S-ROTA operating manual Information Metal Tube Rotameter may be used only for flow measurements of fluid and gaseous media. The manufacturer shall not be liable for damages that may result from unintended or inappropriate use. When dealing with an aggressive medium, clarify the material resistance of all wetted parts.
SMERI S-ROTA operating manual 2.2 Working Principle The flow meter consists of a measuring tube and a float inside it. The flow pushes the float to an equilibrium point. The area obtained between the float and the tube is proportional to the flow rate.
SMERI S-ROTA operating manual 7.For the digital LCD display type, the flow range of the instantaneous flow can be corrected on-site based on the different measuring medium. 8.It adopts advanced six level data backup technology, data of total flow can be saved automatically when power-off, (the total flow sending period is 0.3S).
