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.
