【Discussion】On the issue of measuring the flow rate of materials in pipelines using instruments
Thread Content
Recently, I encountered a problem when selecting vortex flowmeters: in order to ensure measurement accuracy at low flow rates, the measurement pipeline was reduced in diameter. However, at the maximum flow rate, the flow velocity can reach 31.6 m/s (with the medium being saturated steam at 165°C). I would like to ask those of you who have experience with installing such instruments whether this setup meets the standard requirements.
A high flow rate affects the pressure loss. Steam at 165, flow rate slightly higher at 32. However, I think it’s necessary to verify the flow range on the user side; for conventional steam vortex flow meters, a range of 10:1 is usually sufficient. Is there a significant variation in the flow rate downstream? Vortex flow meters are widely used in applications involving 6-inch pipes and 3-inch flow meters.
