2. Installation suggestions for the front and rear straight pipe sections of the turbine flowmeter

Installation suggestions for the front and rear straight pipe sections of the turbine flowmeter The length of the front and rear straight pipe sections of the turbine flowmeter is crucial to ensure that the fluid forms a stable flow state before and after passing through the flowmeter, which directly affects the accuracy and reliability of the measurement. The following are installation suggestions for the front and rear straight pipe sections based on the specifications, manufacturer recommendations, and standard specifications of the turbine flowmeter:

1. The length of the front straight pipe section (upstream straight pipe section) is generally recommended to be 10 to 20 times the inner diameter of the pipeline (D). The setting of this length aims to ensure that the fluid is sufficiently stable before entering the turbine flowmeter and eliminate the possible impact of fluid turbulence or eddies on the measurement. Specifically, fluid stability: A sufficiently long straight pipe section can ensure that the fluid reaches a stable state before flowing into the flowmeter, reducing measurement errors caused by uneven fluid velocity distribution or eddies. Eliminating interference: By increasing the length of the front straight pipe section, it is possible to effectively eliminate the interference of bends, valves, and other components in the upstream pipeline on the fluid flow state, ensuring that the fluid enters the flowmeter in a stable state. Secondly, the length of the downstream straight pipe section is generally recommended to be 5 to 10 times the inner diameter of the pipeline (D). The setting of this length aims to ensure that the fluid can return to a stable state after flowing through
