1 BASIC INFORMATION
1.1 Application
FLONET FH30xx is an electromagnetic flowmeter intended for measurement of volume flow rate of electrically conductive liquids in closed piping. The meter facilitates high-accuracy bi-directional flow rate measurements at flow velocities ranging from 0.025 to 10 m/s. The minimum required conductivity of the measured flui d is 10 μS/cm, for de-mineralised water it is 20 μS/cm.
1.2. Measurement principle
The function of electromagnetic flowmeter is based on the Faraday induction law. The meter sensor consists of a non-magnetic electrically non-conductive tube and two inbuilt electrodes that pick up the induced voltage in a plane perpendicular to the direction of the magnetic power lines. The magnetic field is generated by electric current flowing through two coils wound on the tube. The flow of the conductive l v
U
B liquid through the tube gives rise to induced voltage U proportional to the magnetic flux density B , flow velocity v and the length of the virtual conductor l :
U = B × l × v induced voltage flux density distance between the measuring electrodes flow velocity of the measured liquid
For the given sensor size, the values of flux density and distance between electrodes are constant.
Therefore, the voltage induced on the electrodes is proportional to the velocity of the liquid flowing through the sensor tube. The volume flow rate is then the product of the liquid flow velocity and the tube cross-section: Q = v × S .

Maximum permitted temperature TS (
°C)
Electromagnetic flowmeters FH30xx are intended for flow rate measurements with the fluid flow velocity within the range of 0.025 to 10 m/s. In practical situations it is recommended to limit the fluid flow velocity values to the range of 0.5 to 5 m/s. At low fluid flow velocities, the relative measurement error tends to increase, while at high velocities flow turbulences may occur.
If the inner sensor diameter is the same as those of the connecting piping, the pressure loss at the meter sensor is negligible.
If the operating fluid flow velocity is too low and the measurement error too high it is possible to increase the fluid velocity by using a meter sensor of a smaller size with the corresponding reduction of the inner diameters of the connecting pining. The disadvantage of this solution consists of a pressure loss at the pipe reduction area. Therefore, in practical situations, to reduce the pressure loss to a reasonable value, the pipe size reduction should be limited to a single degree.
Fluid flow velocity in a piping can be calculated using the formula: v =
0.

4.4 Installation conditions
4.4.1 General principles
Applicable to mechanical installation of the flowmeter are the following rules:
•
The protection covers and packaging shall only be removed immediately before the meter installation;
•
The arrow on the sensor housing shall point at the positive fluid flow direction;
•
In cases of sensor installation into vertical piping the fluid flow direction shall be upwards;
•
The piping flanges shall be parallel to one another;
•
The inner piping and seal diameters shall correspond to the inner sensor diameter;
•
The seals and grounding rings shall be correctly fitted between the flanges and not extend in the flow profile;
•
The piping supports before and after the flowmeter location shall minimise the mechanical stresses acting on the sensor (vibration, tension, bend and others);
•
No piping support shall be located under the meter sensor;
•
The transmitter shall be protected from direct sunshine;
•
The meter installation location shall be selected so as to ensure easy access for the operator to the transmitter and all meter rating plates;
•
The meter sensor shall always be fully flooded by the measured fluid to avoid aeration;
•
In cases of electrically non-conductive piping the measured fluid shall be grounded by means of grounding rings.
The sensor shall be inserted between the piping flanges by a shifting movement. With larger sensor sizes it is recommended to use installation inserts. It is also advisable, during the sensor insertion in the piping, to protect the sealing surfaces on the lining by a metal sheet or similar material.
Following the meter installation, no subsequent electric-arc welding operations shall be carried out on the piping at the sensor location. In particular, avoid welding on the piping flanges connected to the meter sensor.
4.4.2 Straight piping sections
To ensure correct functioning of an electromagnetic flowmeter, conditions shall be provided for continuous fluid flow and flow profile stability in the meter sensor.
Before and after the meter sensor there shall be straight piping sections the required lengths of which are specified as multiples of the inner piping diameter. In cases of bi-directional measurements, the same requirements concern straight piping sections before and after the sensor. If there are flowdisturbing elements (such as bend or fitting) in the piping near the sensor location, the required length of straight piping section shall be increased – multiplied by the number of such elements.
At the contact plane between the sensor and the attached piping there shall not be any protruding edges causing the flow turbulence. The inner diameter of the piping shall not be smaller or greater by more than 3% than that of the sensor.
Avoid sensor placement at locations where at the sensor input are chemicals (especially chloride compounds) injected or dosed in the measured fluid. Imperfect blending of the fluid components may cause errors in the flow rate measurements or, in extreme cases, reduction of the measured flow rate to nil.
Preferable are flowmeter sensor installation locations before any piping elements affecting the smooth flow of the measured fluid.
In cases of bi-directional flow measurement, the basic required length of straight piping sections in front of and behind the flowmeter is 5DN.

Installation of a flowmeter of a smaller size than that the attached piping requires the use of cone-shaped reduction pieces with the angle of inclination not exceeding 15°.
In cases of sensor installation in horizontal piping, to prevent generation of air bubbles in the fluid, it is recommended to use eccentric reduction pieces (see standard EN 6817).
Reduction pieces with angle of inclination up to º can be included in the straight piping length.
4.4.3 Suppression of the pump effects
To prevent creation of a low-pressure zone in the sensor and possible damage to the sensor lining, a pump shall always be placed before (at the input side of) the sensor. The length of the straight piping section between the pump and the sensor shall be at least 25 DN.
Placing the pump before the meter sensor reduces the cavitation effect and release of gases from the measured fluid. Increased pressure in the piping system will keep the fluid above the saturated vapour pressure and prevent cavitation effects.

ELIS PLZEŇ a. s.
The movement of the fluid in piping should be continuous and stable. If a pump generates fluid pressure pulses (e.g. pneumatic pump), a suitable pulse damping device should be included in the piping.
Correct pump position
4.4.4 Suppression of the effects of closing valves
To eliminate the disturbing effects on the fluid flow velocity profile in the sensor and prevent the action of the cavitation phenomenon, the closing and throttling valves shall always be located after (at the output side of) the sensor.
Correct valve position
4.4.5 Suppression of vibration effects
Mechanical stresses and vibrations acting on the meter sensor might be detrimental to its function or integrity. It is therefore necessary to fix the position (support) the attached piping as close to the sensor housing as possible. It is assumed that the number of events involving particularly large stresses on the piping, such as filling or draining the piping system, or major fluid pressure changes, does not exceed
1,000 over the meter lifetime.

4.4.6 Piping stacks
Electromagnetic flowmeter FLONET FH30xx
The nearest stack on the piping system on the sensor input side should be at the distance of at least
20DN from the sensor.
4.4.7 Sensor flooding
The meter sensor shall be completely filled with the measured fluid at all times. In cases where complete flooding of the whole cross-section of the connecting piping cannot be ensured, the meter sensor shall be located at such spot where this condition is always met
Permanent sensor flooding
4.4.8 Free discharge points
The sensor shall not be located at the highest piping section or in a vertical piping section with the flow direction downwards, especially in cases where a free discharge point is close by. Observation of this rule will prevent measuring errors due to a higher air bubble concentration within the sensor.
Free discharge Risk of fluid aeration
The sensor will work equally well in both horizontal and vertical positions. However, care shall be taken that the measuring electrode axis in the sensor be to the extent possible in a horizontal plane and the fluid flow direction be upwards.
The permitted deviation of the electrode axis from the horizontal plane is 15° in both fluid flow directions.
The free discharge point shall be higher by 2DN than the sensor output end.

4.5 Tightening torque
Electromagnetic flowmeters of the type series FH30xx are supplied without bolts, nuts and other fasteners or sealing elements.
The entity contracted to perform the meter installation work shall provide the necessary fasteners and seals and carry out the installation work in observance of the applicable standards, paying due attention to the given operational requirements and conditions.
Electromagnetic flowmeters with PTFE lining do not require any additional sealing. The sealing function is facilitated by the flared sensor lining. However, it is necessary for the sealing planes on the piping flanges to be free of any sharp edges. Due attention shall also be paid to observance of the recommended tightening torque.
Rubber and E-CTFE-lined sensors require the use of special sealing elements.
In cases where the meter sensor is to be attached to flanges made glass, ceramics, enamel or other smooth-surface materials, it is recommended to use additional sealing rings at the contact planes. The tightening torque shall be determined with respect to the specific material properties of the connecting flanges.
The sealing material shall not contain any electrically-conductive components that might get loose during the sensor operation, collect on the sensor lining and deteriorate its insulation properties.
Bolt tightening:
•
Tighten the flange bolts using a suitable torque wrench, never an impact wrench.
•
The connecting bolts shall be undamaged, preferable new, slightly greased.
•
Stop tightening the bolts as soon as the required tightness has been achieved.
•
Tighten the bolts along the flange perimeter in a crosswise manner, each in three steps: 50, 80 and
100% of the specified torque. Do not use torque in excess of the recommended/specified value.

4.6 Thermal insulation
When installed in thermally insulated piping, to prevent unnecessary heat loss, the meter sensor is usually provided with thermal insulation too.
In such cases, the following rules need be observed:
•
Insulation shall be applied onto the meter sensor only;
•
Maximum surface temperature of the sensor, whether thermally insulated or not, shall not exceed the values given in Section 3.4;
• The maximum insulation thickness shall not exceed 40mm (the thermal conductivity coefficient λ
0.045 (Wm -1 K -1 ) at 50
C; see standard EN 13787);
D
≤
•
In the cases of compact meter version, the part connecting the meter sensor and transmitter shall always remain bare;
•
The transmitter shall be protected from additional heating (by direct sunshine or heat emanating from nearby equipment).
4.7 Flowmeter heating
In measuring fluids with sub-zero operational temperatures, or at ambient temperatures close to the specified minimum fluid temperatures, it is permitted to provide the meter sensor with thermal insulation and auxiliary heating system.
•
The sensor heating can be facilitated by electricity or a suitable heat-carrying medium supplied through a special piping system;
•
In cases of electric heating, it is recommended to use a regulated AC power source with current switching at zero.

The other end of the cable is provided with a connector facilitating connection to the meter transmitter.
5.3 Power and information cables
In operating environments free of explosion risk, the power and information cable connections do not require any special arrangement. Applicable to the meter installation work are standard procedures known from conventional measurement and control systems. However, due attentional shall be paid to the applicable national regulations and standards.
The flowmeter does not include any integrated line circuit breaker. Unless the meter configuration includes a moveable power cord and plug, a separate power switch or circuit breaker shall be used (see the provisions of section 6.11.3.1 of standard EN 61010-1).
The protective conductor of the power supply cable to be connected to the PE terminal must be longer than the L and N conductors. The PE conductor must be disconnected as last if the power cable is removed from the bushing. This PE terminal is located at the bottom of the terminal box of the instrument box.

5.4 Cable placement
To minimise the effect of electromagnetic interference, the cables connecting the sensor and the meter transmitter shall be laid at least 25cm away from the power cables of other electric equipment.
In selecting cable routes, attention shall be paid to the risk of thermal degradation of the cable insulation due to nearby technological heat sources. All cables shall be laid outside the thermal insulation layers on piping.
The cable glands shall be properly sealed and tightened with suitable tooling. To prevent cables from being pulled out of the glands, their position shall be mechanically fixed no further than 0.3m away from each gland.
Outside the gland , the cable shall be bent to form a “dripping loop” the straight length of about 30mm of the cable is led horizontally from the gland and then bent down to form a loop).
5.5 Power supply specifications

The pulse length in cases of electronic determination of the fluid volume passed through the sensor is recommended to be set at P min
= 5ms, which meets the condition for f max
at the pulse output equal to 100Hz. In cases of electro-mechanical counters, P min
is usually set at 50ms, corresponding to the maximum frequency at the pulse output of 10Hz.
Example:
Assume that a user specified for their flowmeter of DN100 the maximum operating flow rate:
Q max

5.7 Grounding and potential equalising
To guarantee correct operation of the FH30xx electromagnetic flowmeter, it is necessary to ensure that the potential of the measured fluid before and after the flowmeter, the reference meter potential and the
PE protection conductor be equalised with the ground potential at the meter installation site. For the equipment grounding and potential equalising, use Cu conductor of cross-section 4mm 2 .
The external PE terminal on the transmitter box shall be internally connected to the reference meter potential.
Electrically conductive piping
Flanges on the conductive piping shall be connected to the PE terminals on the sensor and transmitter housings and to the ground potential.
The bolted connections between the piping and sensor flanges cannot be taken for a reliable and satisfactory conductive connection. It is recommended to provide threaded holes on the flanges for a reliable bolted connection of the grounding/equalising conductor.
It is not recommended to place the grounding or equalising conductors under the heads of the main flange bolts; such connection may be subject to corrosion and adversely affect the measurement accuracy.

Piping made of insulating materials or piping with insulating lining
In such cases, the requirement for the fluid potential equalisation shall be met by two grounding rings installed before and after the flowmeter. Each grounding ring shall be inserted between two sealing rings.
The grounding rings are not included among the standard meter accessories , but they can be ordered with the product. Regarding chemical stability and resistance with respect to the measured fluid, the grounding rings shall meet the same criteria as the measuring electrodes.
In the cases of remote meter version, the PE terminal on the meter sensor and the transmitter box shall be interconnected by a Cu conductor of cross-section 4mm 2 .
This connection shall not serve the purpose of potential equalisation with any other equipment or devices.

Piping with cathodic protection
If an electromagnetic flowmeter is to be installed into piping with cathodic protection, it is necessary to ensure that all flowmeter parts be electrically insulated from the piping. At the same time, the meter power source shall be insulated from the power grid. To ensure the overall piping conductivity, the installed meter shall be bypassed by Cu conductor of cross-section 6 mm 2 (connected to the piping flanges before and after the flowmeter).
The fluid potential shall be equalised with the reference meter potential (the PE terminal potential) by means of grounding rings. The grounding rings shall also be insulated from the piping.

9 CALIBRATION
9.1 General
The flowmeter is supplied verified as to its functions, calibrated and with parameters set according to the customer’s requirements.
The measurement accuracy of the flowmeter in its standard form and configuration is guaranteed to meet the provisions of the international standard EN ISO 4064-1 : Water meters for cold drinking water and hot water .
Unless agreed otherwise with the customer, the flowmeters are calibrated using the frequency output 0
– 10kHz.
Upon special requirement and agreement with the flowmeter manufacturer, the meter calibration may be carried out using alternative, i.e. pulse or current outputs.
The guaranteed measurement accuracy parameters shall always be related to the type of output which was used for the meter calibration. The remaining two types of output are recommended to be used for measurements with accuracy lower by 1 to 2% compared to that associated with the calibrated output.
For inspection or comparison measurements at the customer’s premises, or metrological verification of the meter parameters, the same type of electric output as that used for the initial calibration at the manufacturing plant shall be selected. Such measurements shall be performed under specified reference conditions.
At such measurements it is important to connect the hydraulic meter section (the sensor) into the hydraulic circuit on the test stand using connection elements (flanges, threaded fittings, fittings used in food-processing lines or others) of the same type, size and design as found on the meter sensor, to prevent occurrence of hydraulic disturbances that might significantly affect the meter measurement accuracy.

10 METER DESIGN DETAILS
10.1 Transmitter
Transmitter C14.00/C15.00 is fitted in a box made of aluminium alloy with removable front and rear covers.
Behind the window in the front cover there is a backlighted OLED display of 128x64 pixels. The flowmeter control is facilitated by optical buttons (optical reflex sensors) actuated by touching the respective spots on the front window.
The transmitter terminals can be accessed upon removal of the solid rear cover. When closed, the lid position is secured by means of an Allen bolt.
External cables can be brought into the terminal compartment via two glands accommodated in threaded holes M20 x 1.5. Should the meter configuration or higher number of output signals require so, inserted in the cable gland can be a sealing insert with more holes to hold the required number of cables.
This sealing insert is not included among the standard meter accessories.
Located at the top of the transmitter box is a grounding bolt and a flat area intended for the flowmeter rating plate. The transmitter plate is attached to the rear cover on the transmitter housing.
The surface finish of the housing consists of powder paint coating.
The connections of the transmitter terminals are described in Chapter 5 (ELECTRICAL CONNECTIONS).
The transmitter for the compact meter version (including a sensor of protection class
IP67) is supplied with the signal cable attached.
The transmitter for the remote meter version (used in combination with a sensor of protection class IP 68) is provided with a connector for the signal cable connection. The other end of the signal cable is attached to the sensor where the terminals inside the hermetic connection box are embedded in an insulating compound.
10.2 Sensor
The induction sensor consists of a measuring tube made of non-magnetic steel with insulation lining, two measuring electrodes and, in some cases, one grounding electrode. Located outside the measuring tube is a winding the function of which is to generate electromagnetic field perpendicular to the measuring electrode axis. The excitation winding and measuring electrodes are protected by the sensor housing made of carbon or stainless steel. In its standard design version, the sensor is provided with flanges according to EN 1092-1 or ANSI B16.5. Upon agreement with the manufacturer, other types of flanges can be provided.
The sensor can also be supplied in all-stainless-steel design.

11.4 Fault identification
Make sure to de-energise the meter prior to starting any actions related to fault identification and repair, such as opening the transmitter housing, checking the power cable connections, disconnecting the meter sensor or removing PC boards from the transmitter housing.
Nevertheless, some operations require that parts of the meter or its PC boards remain live. In such cases proceed with utmost care to minimise the risk of electric shock.
Operational/functional tests on the flowmeter can be performed using the RS-485 MODBUS RTU serial communication line and program FLOSET 4.0.
To carry out any on-site meter repair actions the user will need a set of spare PC boards tested and preset at the manufacturing company. Such repair actions consist of replacement of the defective PC boards. If the given type of defect is associated with a malfunction of any specific PC board, the user may try to replace such board upon opening the respective cover of the meter transmitter.
The flowmeter software includes internal control and diagnostic algorithms the purpose of which is to identify meter defects and show the corresponding error code on the meter display.
Should the error code displayed imply a sensor defect, the sensor can be substituted by the sensor simulator SF1.0 (applicable to the remote meter version only).

9. Loosen three bolts M4 and take away the terminal board. Unscrew distance columns M4 x 25 and remove the power supply board from the transmitter housing.
10. Connect both PC boards (the power-supply and terminal boards) removed from the transmitter housing. Bring the external power supply voltage (AC or DC, as the case may be) to the terminal board.
Warning: risk of electric shock
Check on the power supply board
AC power supply 95 to 250VAC
Connect loading resistor 47R to the connector terminals shown in the picture below. After five minutes, the voltage across this resistor shall be in the range of 14.7 to 15.3V. Should it not be so, the power supply board is defective and it shall be replaced.
DC power supply 19.2 to 28.8VDC
Connect loading resistor 47R to the connector terminals shown in the picture below. After five minutes, the voltage across this resistor shall be in the range of 14.7 to 15.3V. Should it not be so, the power supply board is defective and it shall be replaced.

If the power supply section is in order, the cause of the error should be sought in the meter circuits on the PC boards located under the front cover of the transmitter housing.
Procedure
1. Switch off the meter power source.
2. Release the Allen bolt securing the closed position of the front cover on the transmitter housing.
3. Remove the front cover on the transmitter housing.
4. Loosen four bolts M2.5 and take away the cover panel on the display. Remove the display board from the transmitter housing by carefully displacing it in the direction of the transmitter axis.
5. In cases of defective display, replace the display board and check its correct function.
6. Should the error condition continue even after the power circuit and display unit checks, proceed with replacement of the electronic unit. Unscrew four distance columns M4 x 10 and remove and replace the electronic unit (consisting of the processor, output and measuring PC boards mutually interconnected by the connector board). Verify the flowmeter functions.
Upon the meter re-installation, tighten the bolts on the transmitter and sensor covers using the torque not exceeding 8Nm.
Upon replacement of the electronic unit it is not necessary to repeat the meter calibration procedure.
Using the FLOSET 4.0 software, restore the original setting of the meter parameters.
Should you fail to rectify the meter defect using the above procedures, contact the authorised flowmeter service centre or directly the meter manufacturer.

12 MAINTENANCE
The FLONET FH30xx flowmeter does not require any special maintenance. During regular product inspections, apart from visual check on the mechanical integrity and absence of signs of damage to the external meter parts, it is recommended to check the tightness of cable glands and grounding terminals.
Transmitter
The transmitter housing exterior is coated with a layer of powder paint. For cleaning, use standard procedures applicable to maintenance of measuring devices.
Sensor
When cleaning the viewing window and rubber seals, avoid application of abrasive cleaning agents.
To clean the sensor surface, use standard procedures applicable to maintenance of measuring devices.
The PIGS method (mechanical cleaning) is not permitted for maintenance of the inner parts of the sensor as it implies a risk of damage to the sensor lining and measuring electrodes. The inner surfaces of a dismantled sensor should be cleaned using a piece of cloth or brush and a cleaning agent with degreasing and mild abrasive effects (for example a liquid cleaning cream).
