Application scenarios of turbine flowmeters

Thread Content

1. Turbine flowmeters are highly affected by the flow field distribution; therefore, for flowmeters without an inlet rectifier, straight pipe sections must be installed on both the upstream and downstream sides of the sensor as required. For flowmeters with an inlet rectifier, the length of these straight pipe sections should also be set in accordance with the instructions provided. 2. It is not suitable for use in situations with strong pulsating flows, nor is it appropriate for measuring multiphase flows. 3. High cleanliness requirements are imposed on the medium being tested, and filters must be installed as required; however, this also leads to an increase in pressure loss. 4. The flow characteristics of small-diameter turbine flowmeters are greatly affected by the properties of the fluid, which makes it difficult to improve their performance. For example, if the small diameter is DN25, its range ratio is only 10:1, with a precision of merely ±1.0%. 5. It is not allowed to be used in environments with rapid switching.
