  • Page 24 Instruction Manual HOW TO AVOID AIR POCKETS IN THE PIPELINES This paragraph is intended to help the designers and users of electromagnetic flowmeters to create the best installation layout that guarantees optimum performance of the meter, taking into particular consideration the problem of the presence of air pockets in the pipe.
  • Page 25 Instruction Manual Fig. 31 Air pockets inside the pipe The greater the diameter of the pipe, the higher the speed of the liquid will be required to move the air pockets away from the flowmeter. It is also important to understand what kind of effect the water pressure has on the nature of the air pocket inside the pipe.
  • Page 26 Instruction Manual Drawings are made with an exaggerated slope for clarity α = 0,15° α = 0,15° Fig. 34 Flowmeter with slight ascending slope with air vent at the top A second solution is to mount the flowmeter vertically with an upward flow stream, which ensures that the air always moves quickly past the meter.
  • Page 27 Instruction Manual The design of the vent valve is essential to ensure that the entrapped air pockets are released. Pneumatic valves or vacuum switches should be avoided. Instead, it is preferable to use combined pneumatic valves that incorporate an automatic orifice, as well as a large kinetic orifice. These valves ensure that the largest volumes of air are released quickly and effectively while filling the pipe.
