 Work characteristics 

 A wide temperature range, measured media; 

 At room temperature fluid conditions of the steam flow sensors continue to stream line repair. 

 3, simple structure and solid, no moving wear parts, long life; 

 4, the vortex steam flow measurement accuracy is high, loss of resistance; 

 5, easy installation, small amount of maintenance; 

 6, the steam flow meter long-distance transmission of traffic signal, to achieve centralized management.
