Page 6: Sensor Flomat-Fx
SENSOR FLOMAT-FX WORKING PRINCIPLE The FLOMAT 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. INSTALLATION This should be made in a straight pipe run that guarantees that the pipe is always completely full and where there is a fully developed turbulent flow profile (follow indications on point 4.2). Avoid high points of the pipes where air pockets usually form, or pipes with downwards flow where vacuums can occur. -
Page 8: Straight Pipe Sections
Straight pipe sections The point where the FLOMAT sensor will be installed must be a straight pipe section, separated from elements that can disturb the flow profile, such as elbows, diameter changes, etc. Depending on the element the minimum necessary distances upstream from the sensor are shown on the next page (BS 1042-2.2:1983 standard). - Page 9 Disturbing element Minimum distance between upstream the the sensor and the element sensor 90º elbow Several 90º coplanar bends Several 90º non- coplanar bends T accessory Total angle convergent 18 to Total angle divergent 14 to 28° Fully opened butterfly valve Fully opened plug valve...

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. 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. -
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 Pipe adaptor mounting The sensor is normally supplied mounted in its pipe adaptor. Before welding the adaptor to the pipe, the sensor must be removed to avoid irreparable damage due to excessive temperatures. There are two basic types of pipe adaptors: with threaded or with flanged connection. For the smallest pipe diameters (DN40, 50 &... - Page 13 As shown in the following table, to know the distance, the thickness of the pipe s must be known. In order to make the positioning of the pipe adaptor in the pipe easier, there is a label on one of its sides with markings indicating the position of the internal pipe diameter for each DN. Cut this label above the line corresponding to the DN of the pipe, at a distance equal to the pipe thickness.
-
Page 14: Sensor Mounting
Example: Suppose a pipe of 300 mm inner diameter (DN300) and 5.5 mm thick. In the chart we can see that the distance that the pipe adaptor must extend above the external wall is H = 60.5 - s = 60.5 - 5.5 = 55 mm. The values in the chart are calculated considering the gasket supplied with the instrument, which is 3 mm thick. -

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. -
