6. Mechanical connection 

  Please ensure that the permitted values of maximum pressure and 

temperature are not exceeded. 

  The recommended filter size is 40µm. 

  The flowmeter should be installed vertically with flow from bottom to top. 

  Fibrous seals should be avoided as pieces can cause damage to the unit if 

they enter the flowmeter. Connection should only be made using a correct fit-
ting and appropriate seal. 

  We recommend that you pressure test the unit for leaks after installation. 

 
 
 

7. Electrical connection 

  When wiring the plug or making electrical connections to the flowmeter please 

ensure that the power supply is isolated. 

  Electrical connections should be made according to the diagram. 

 

Attention! Incorrect wiring may cause damage to the electronics. 
Check!
