 Local indication, volume totalizer, 4-20 mA and pulse Working principle The measurement principle is based on Faraday’s induction law. A voltage V is induced between a pair of electrodes when a conductive liquid flows in a pipe of diameter D at an average velocity v, through a magnetic field B (which is perpendicular to the flow direction). This voltage, proportional to the average velocity of the liquid, is acquired by the electronic converter in order to be processed and converted to a flow rate measurement. V=B·v·D V = Voltage across the electrodes v = Liquid velocity  Alarms, empty...

Electromagnetic flowmeters Series FLOMAT Models In case of metallic or plastic pipe where Tecfluid insert pipe adaptor can be supplied (see p. 2), installation can be made by welding or gluing the adaptor as follows: In those cases where Tecfluid insert pipe adaptor cannot be used (FRP or similar pipes), installation should be made by means of a CLAMP-ON saddle (not supplied): CLAMP-ON saddle for non-metallic pipes CLAMP-ON saddle for plastic pipes Insert pipe adaptor Sensor body EN 1.4404 (AISI 316L), Hastelloy C, Titanium, Tantalum, Zirconium * Also available in EN 1.4404 (AISI 316L) on...

Sensor with compact converter * minimum dimension to remove the flowmeter from the pipe Insert pipe adaptor There are two different types of insert pipe adaptors. For pipe size DN40 ... DN65, insert pipe adaptor is supplied already welded to short length of pipe that must be just coupled to the pipe by welding or gluing (in the case of PVC). For pipe size of DN80 or bigger, insert pipe adaptor is directly welded (or glued) on the pipe. Insert pipe adaptor DN s: pipe thickness (depends on pipe material and pressure rating) C: penetration depth Sensor with remote converter (IP68 10 m H2O)

Electromagnetic flowmeters Series FLOMAT Flow ranges Sensor selection The diagram shows the correspondance between the liquid velocity and the flow rate for different sensor sizes. The sensor size should be chosen selecting a liquid velocity of about 3-4 m/s. The minimum liquid velocity should not be below 0.5 m/s. When the liquid has solids in suspension, it is better to work between 3 and 5 m/s in order to avoid sedimentation in the pipe and sensor. 1000 Accuracy curve (error vs velocity) ± e (%) 30 v ≥ 0.4 m/s v < 0.4 m/s e = ± 3.5% reading value e = ± [1.4 / v (m/s)] % reading value...

Electronic converters Different models of electronic control units are available to comply with the options of flow indication, maximum / minimum flow rate control, analog and pulse outputs. All of them are compatible with the different FLOMAT-FX sensor models. Time These converters can be supplied for compact mounting directly on top of the sensor or for remote mounting. Cable is supplied. HART protocol is available for both MX4 and XT5 converters. Modbus RTU protocol is available for MX4 converter. Pulsed coil excitation XT5 converter Remote mounted converter (model XT5M) Technical data...
