Items with WELDED SOCKET

 

 

 

 

The welding socket is included in the delivery. Remove by loosening union nut (A). The 
dimensions shown in the drawing (right) must be adhered to strictly to. Drill a ridge less hole in 
the pipe. Weld the socket to the pipe. Mount the flow transmitter to the socket ensuring that 
the pendulum is not damaged during this procedure. Align the transmitter into the final desired 
position before tightening the union nut (A). Please do not forget to keep the flow direction in 
consideration before weld on the socket. (groove)

Torsional moment of the union nut

  

 

If the device shall be divided from the t-piece or the welding socket, the union nut has to be 
disconnected and the device carefully taken out of the housing. 

 

If both pieces are assembled, please take care that the nut is tightened with a torsional 
moment of 40Nm.
