Globe Type Flow Switches (Plug Type)
  
DAG Flow switches are Globe Body Design used to detect Flow / No-Flow condition in a flow line. With sufficient Differential Pressure upstream and downstream of a calibrated Flow Plug; fluid flow is established. Increase in fluid flow moves the Flow Plug upwards which carries a Magnetic Sleeve attached through a Connecting Link, upwards inside a process seal pipe. When this Magnetic Sleeve enters the Flux zone, a permanent magnet swings towards the seal pipe. This movement actuates a Microswitch (NO-NC-COM) change-over contacts and vice-versa. (Calibration has to be done against a Rotameter in work shop and is slightly settable). Mainly Flow-No Flow detection is achieved.

 
 
Vane Type Flow Switches
  
DAG Flow switches are Vane / Paddle Design used to detect Flow / No-Flow condition in a flow line. With sufficient Differential Pressure upstream and downstream of a Flow Vane; fluid flow is established. Increase in fluid flow moves Paddle towards a side which in turn moves a Magnetic Sleeve, attached through a Connecting Link, upwards inside a Process Seal Pipe. When this Magnetic Sleeve enters the Flux zone, a permanent magnet swings towards the seal pipe. This movement actuates a Microswitch (NO-NC-COM) change-over contacts and vice-versa. (Calibration has to be done against a Rotameter in work shop and is slightly settable). Mainly Flow-No Flow detection is achieved.
