Page 6: Sensor Flomid-Fx
SENSOR FLOMID-FX 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 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: 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 level difference 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: Vibrations
Vibrations Vibrations of the pipes should be avoided by anchoring the pipe before and after the sensor. The vibration level should be less than 2.2 g in the range of 20 -150 Hz according to IEC 068 -2-34. Magnetic fields Strong magnetic fields close to the sensor should be avoided. -
Page 12: Temperature
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 point 14 of page 37. -
Page 13: Mounting
MOUNTING Parallelism The maximum parallelism error must be less than 0.5 mm (Lmax—Lmin ≤ 0.5 mm). Gaskets 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 14: 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 15: Tightening
Earthing rings are supplied in two versions: Dimensions in mm Metallic Plastic 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. -
Page 16: Xt5 Converter
XT5 CONVERTER INTRODUCTION The XT5 converter unit can be used with the different FLOMID and FLOMAT series of electromagnetic flow sensors. The electronic circuit is based on the most advanced technology, in order to obtain accurate and reliable measurements. The device provides the following features: •... -
Page 17: Remote Converter
2.1.2 Remote converter One of the ends of the cable has a header and two wires, to connect them to the sensor. The connection is as explained in point 2.1.1. The other end has to be connected to the converter, and has five wires. The cable must be passed through the cable gland and the connection for each wire is explained in chapter 3. -
Page 18: Power Supply Wiring
2.2.1 Power supply wiring Before connecting the converter, check that the supply voltage available is the same as marked on the label of the instrument. Terminal AC power supply DC power supply Earth Earth Neutral Phase 24 V (+) It is important to connect the mains earth to the instruments with AC power supply due to the presence of a mains filter inside that requires this connection. - Page 19 The analog output is galvanically isolated. It can be either active (that means the receptor must be passive) or passive (that means the receptor must supply the power for the current loop). It is recommended to use a receptor with an input resistance of less than 700 Ω to guarantee correct operation.

Page 20: Pulse Output Wiring
2.2.3 Pulse output wiring Terminal Emitter Collector The pulse output is opto-isolated. The terminals are the collector and emitter of an NPN bipolar transistor. In the case of using inductive loads, in order to protect the output transistor, the use of free wheeling diodes is required. -
Page 21: Remote Sensor
REMOTE SENSOR When an installation requires that the electromagnetic sensor is separated from the control unit, the union between these two elements must be made by means of an interconnection cable. Normally, these cables are supplied by Tecfluid S.A., already prepared for their direct connection to the sensor and the converter. -
Page 23: Cable Connection To The Sensor
Cable connection to the sensor For the sensor connection, first loosen the cable gland to allow the cable to slide in it. • Make sure that the two fixing screws of the cover do not protrude inside the cover (this avoids damaging the o-ring of the sensor neck). -

CONVERTER INTERFACE The XT5 converter has an LCD and a keyboard with 3 capacitive buttons to introduce the values of installation and programming. Two of these keys are used also as cursors. The following figure shows the functionality of the converter keys. (Left) To change to the digit on the left. -
Page 27: Installation Parameters
The equipment is normally delivered calibrated and configured with its sensor so that it indicates the true flow rate and volume. If any configuration parameter is to be changed, this can be done without having to remove the top cover. If the instrument has not been previously configured or, due to alteration of data in the memory the instrument recovers the default configuration, the word “PRESET”... -

Page 29: Converter Programming
CONVERTER PROGRAMMING By means of the converter programming, the visualization and the outputs of the instrument can be configured. □ Power on the electronic converter and touch the two keys (↑) y ( ) at the same time. The first programming screen is accessed for the visualization and output parameters. -
Page 30: Pulse Output
Pulse output In this screen, there are two options. a) Frequency output (Hz). This is meant for transmitting the instantaneous flow rate to a remote unit. The output pulse frequency for a flow velocity of 5 m/s is programmed here (see limits in point 14). - Page 31 Only the flow rate indication of the display and the analog output are affected by the filter. The pulse output and the totalizer act according to the instant flow rate. By selecting a filter with a longer or shorter integration time, responses to flow rate variations in more or less time can be obtained.

Page 32: Flow Direction
Flow rate direction In this screen the flow direction for which the flow rate indication will show a positive value can be programmed. Using the (↑) key we change the positive flow direction from left to right (R) to right to left (L). Note: In a FLOMID sensor the left and right of the sensor are when looking at the sensor in a horizontal pipe and with the earth connection stud at the back. -

In order to see the software version and return to the normal working screen, touch any key. EMPTY PIPE INDICATION When the XT5 converter detects that the pipe is empty the flow rate indication will disappear and in its place 4 dashes will be shown. -
Page 34: Changing The Position Of The Display
CHANGING THE POSITION OF THE DISPLAY To change the orientation of the display in order to adapt it to the instrument mounting position, first disconnect the equipment from the power supply and remove the front cover.
