Page 6: Working Principle
WORKING PRINCIPLE The FLOMID electromagnetic flowmeters 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 Vm 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: Mixtures
4.2.1 Mixtures If liquids of different conductivities are mixed it is necessary to install the sensor a minimum of 30 DN from the point of mixture in order to obtain a uniform conductivity of the liquid and stabilize the readings. If this distance is shorter, readings may be unstable. -
Page 10: Aeration
Aeration If there is a point where the difference in level is higher than 5 m an air inlet valve should be installed after the sensor to avoid a vacuum effect that could damage the sensor liner. 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... -
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 The maximum liquid temperatures are shown on page 53. -
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 mounted sensors, in order to avoid leakage of the liquid into the sensor, it is necessary to ensure that the rubber gasket (A) of the figure is well centered, so that it presses directly on the plastic liner. -
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 Torque
Earthing disks are supplied in two versions: Metallic, disk in stainless steel EN 1.4404 (AISI 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... -

Page 37: Offset
7.4.5 Offset In order to obtain a perfect linearization of the instrument, it is recommended to make an adjustment of the zero offset each time an installation is performed. The flow rate must be zero, that is, the liquid inside the pipe where the flowmeter is installed should be completely stopped. -
Page 38: 7.5.1.1 Alarm
7.5.1.1 Alarm If “Alarm” is selected, we have access to program the flow rate at which the relays will change its status and to the level of hysteresis. By level of hysteresis we understand the difference between activation and deactivation of the output. To avoid that an alarm output is continuously moving from activate to deactivate status, we must program the points of connection and disconnection. -
Page 39: 7.5.2.2 Units
If “Unidirectional” is chosen, the output will give pulses proportional to flow rate when the flow rate is positive, and will not give them when the flow rate is negative. If “Bidirectional” is chosen, the output will give pulses proportional to flow rate in both flow directions. -
