Thermal mass flow meter Installation position and requirement for pipeline
Thermal mass flow meter Installation position and requirement for pipeline
1.The installation of instrument should be far away from the elbow, obstacles, reducer, valves,
in order to assure a stable flow field, typically.Have a long straight pipe up and down, straight
long before more than 10 d, straight after long is greater than 5 d.
Often met in the figure below shows several ways of straight pipe required.
NO. | Pipeline In front of the pipe section | The back pipe section | |
(1) | straight pipe | 10 D | 5 D |
(2) | bent pipe | 10 D | 5 D |
(3) | flared tube | 15 D | 5 D |
(4) | downstream of the valve | 20 D | 5 D |
(5) | shrink tube | 20 D | 5 D |
(6) | Under the pump | 30 D | 5 D |
