Page 6: Working Principle
WORKING PRINCIPLE The FLOMID electromagnetic flowmeters converter are based on Faraday’s induction law. When an electrically conductive liquid flows through a magnetic field, perpendicular to the flow direction, it induces a voltage V proportional to the liquid velocity. Two electrodes in contact with the liquid and positioned perpendicularly to the magnetic field, sense this voltage V. -
Page 7: Handling
HANDLING It should always be done with care and without knocks. The large diameter sensors have rings for holding the elevation elements. If the flowmeter is held using slings, these should hold on the sensor and not on the electronics housing (see drawing). -
Page 8: Sensor Position
Sensor position The most adequate position is with the electrodes in a horizontal plane. In this way, deposits of particles on the electrodes are avoided. Straight pipe sections They are necessary before and after the sensor. The minimum distances are the following: Upstream 5 DN Downstream... -
Page 9: Valves
Valves Control valves or shut-off valves should always be installed downstream from the sensor to assure that the pipe is always full of liquid. Pumps Pumps should be mounted upstream from the sensor to avoid the suction of the pump (vacuum) that could damage the sensor liner. -
Page 10: Reduction Of Dn
Reduction of DN In installations where, due to reasons of the flow rate to be measured, a sensor of a smaller DN than the pipe DN must be mounted, the reduction must be done with an angle smaller than 4º to avoid turbulences that can give false readings. If the angle cannot be so small, straight pipe sections indicated in 4.2 point must be kept. -
Page 11: Magnetic Fields
Magnetic fields Strong magnetic fields close to the sensor should be avoided. Temperature In open air installations it is recommended to install a protection to avoid direct sun light on the flowmeter. With thermally insulated pipes DO NOT insulate the sensor. High temperatures can damage NOTE: High o very low temperatures shorten the battery life. -
Page 12: Mounting
MOUNTING Parallelism The maximum parallelism error must be less than 0.5 mm (Lmax—Lmin ≤ 0.5 mm). Gasket position In the wafer sensors, to avoid leakage of liquid inside the sensor, it must be ensured that the rubber gasket (A) of the figure is well centered, so that it presses directly on the plastic of the sensor. -
Page 13: Sensor Earth Connection
Sensor earth connection To obtain correct operation the sensor should have its functional earth connected to a point that is in direct contact with the liquid whose flow rate wants to be measured. The earth cables should assure a good electrical contact. To obtain this, they should be well screwed down and with a good contact on both sides of the sensor. -
Page 14: Tightening
Earthing rings are supplied in two versions: Metallic, disk in stainless steel EN 1.4404 (SS 316L), for liquids compatible with this material. Plastic, with an electrode to make the contact with the liquid. The materials (plastic and metal) depend on the working liquid. Dimensions in mm Metallic Plastic... -
