Function Measuring Principle

According to Faraday's Law of MagneticInduction, a voltage is induced into aconductor which moves in a magneticfield. With the electromagnetic measur-ing principle, the flowing fluid is themoving conductor. The induced voltageis proportionally related to the flowvelocity and is fed to the measuringamplifier by a pair of electrodes. Usingthe pipe cross-sectional area, the flowvolume is calculated.

The DC magnetic field is generated bya switched direct current of alternatingpolarity. Together with the patented“Integrated Autozero Circuit”, this guar-antees a stable zero point, and makesthe measurement fluid-independent andinsensitive to entrained solid particles.Every meter is factory calibrated withthe most modern calibration rigs, trace-able to national standards.

Function of the Promag 33

The Promag transmitter converts themeasured values coming from thesensor into standardised output signals.The following outputs are available forthese signals:• Current output• Pulse / Frequency output• Alarm output (Relay 1)• Status output (Relay 2)

Promag 33 also has the followingfeatures:• Relay 1 and 2 are freely configurable• Auxiliary input (positive zero return,

totalizer reset, batching, dual rangemode)

• Empty Pipe Detection (EPD) detectsand indicates partially filled or emptymeasuring tubes.

• The special electrode cleaning cir-cuitry (EEC) ensures accurate flowmeasurement even with conductivebuild-up in the measuring tube(e.g. magnetite).

Three operating keys are used forselecting and setting all functions of theinstrument. The E+H operating matrixallows quick and easy access to allindividual functions.12 languages are selectable for thedisplay text. A help function (diagnosisfunction) is available during program-ming.

Communication

Depending on which module is fitted,Promag 33 has different interfaces forcommunication ability with higher levelsystems:• HART protocol (SMART technology)

is possible on the current output.• Direct communication to a personal

computer and the E+H Rackbus worldis possible via the RS 485 interface.

• The PROFIBUS-PA version providesan indirect connection to processcontrol systems via segment couplers.

• Promag 33 is also available as aPROFIBUS-DP version for connectingto a PROFIBUS-DP network.

Diameter Selection As a rule, the pipe diameter determinesthe sensor nominal diameter.

A necessary increase in velocity can beachieved through a reduction of thesensor diameter (see page 8).The higher installation expense isnormally balanced by the lower sensorcost.

The flow velocity (v) is also to be deter-mined by the fluid's physical properties:• v < 2 m/s: with abrasive fluids, e.g.

potter's clay, lime milk, ore slurry• v > 2 m/s: with fluids causing build up,

e.g. wastewater slurry etc.

Mounting

Mounting Position

Vertical mounting:This is the recommended position withthe flow upwards. Entrained solidparticles sink and fatty components inthe stationary fluid rise away from themeasuring electrodes. This is theoptimal position in empty pipe systemand when using Empty Pipe Detection.

Horizontal mounting:The axis of the electrodes must behorizontal, thus preventing brief insula-tion of the electrodes by entrained airbubbles.

Electrode axis:The plane in which the electrode axislies with regard to the transmitter isidentical for the Promag A, H and Fsensors.

Inlet and Outlet Sections

The sensor should be mounted awayfrom fittings such as valves, T-pieces,elbows, etc.

Inlet section: ≥ 5 x DNOutlet section: ≥ 2 x DN

The inlet and outlet sections must beobserved in order to maintain accuracy.

Vibration

The piping before and after the sensorshould be securely fastened if thereis excessive vibration. Information onshock and vibration resistance is foundon page 25.Excessive vibration necessitatesseparate mounting of the sensor andtransmitter.

Mechanical support of the sensor isrecommended for free runs of pipingover 10 m long.

In order to measure correctly and to prevent damage, please observe the followinginstallation instructions.

Mounting Location

Correct measurement is only possiblewhen the pipe is full. The followinglocations should therefore be avoided:

• No installation at the highest point(air accumulation).

• No installation immediately beforean open pipe outlet in a downwardline.

The alternative installation, however,permits a correct measurement.

Partly Filled Pipes

For inclines a mounting similar to a drainshould be adopted. Added security isoffered by Empty Pipe Detection (EPD)in order to detect empty or partly filledpipes.

Note!Danger of solids accumulation!Do not mount the sensor at the lowestpoint of the drain. A cleaning valveshould also be installed.

Downward Pipe

With the installation suggested opposite,partial vacuum is avoided even with adownward pipe > 5 m long (siphon, ventvalve downstream of the sensor).

Installation of Pumps

Do not mount the sensors on thesuction side of pumps.This prevents low pressure and preventspossible damage to the lining of themeasuring tube.

Pulse dampers should be installedwhen using reciprocal, diaphragm orperistaltic pumps.

Mounting Adapters

The sensor can also be mounted in apipe with a larger nominal diameterwhen suitable adapters (reducers andexpanders) to DIN 28545 are fitted.The resultant increase in the rate of flowincreases the accuracy of measurementwith slowly moving fluids.

The adjacent nomogram can be used todetermine the pressure loss caused:

1. Determine the ratio of thediameter d/D.

2. From the nomogram read off thepressure loss at the flow velocityand d/D ratio.

Note!The nomogram applies to fluids with aviscosity similar to that of water.

Remote Version

Two different versions are available forthe remote version:

FS version• The permissible cable length greater

than 10 meters is governed by thefluid conductivity (see Figure).

• Permissible cable length of max.10 meters if the instrument is equippedwith an Empty Pipe Detection (EPD)electrode.

• The FS cable is recommended only fordistances smaller than 20 m.

FL version• All fluids with a minimum conductivity

of ≥ 5 µS/cm (demineralised water≥ 20 µS/cm) can be measuredindependent of the cable length.

• Empty Pipe Detection (EPD) is notavailable with this version.

Please also note the following:• Fasten the cable gland or lay it in a

conduit. When the fluid conductivity islow, cable movements can causeserious changes in capacitance andthereby falsify the measuring signal.

• Do not run the cable in the vicinity ofelectrical machines or switchingelements.

• Ensure potential equalisation betweenthe transmitter and the sensor.

Operation in Areas with Severe Electrical Interference

The Promag 33 measuring system fulfils all general safety requirements accordingto EN 61010 and electromagnetic compatibility (EMC) according to EN 50081 Part 1and 2 / EN 50082 Part 1 and 2 when installed in accordance with the NAMURrecommendations.

Note!• To comply with the certificate of conformity, the signal and coil cables between

the sensor and transmitter of the remote version must always be screened andgrounded at both ends. Grounding is made using the ground terminals especiallyfor this purpose on the inside of the connection housings. Keep stripped andtwisted cable shield section to the ground terminal as short as possible.

• The cable must be resistant to an ambient temperature of max. +80 °C if thePromag H sensor is operated at a process temperature of +150 °C.

12

Potential Equalisation The sensor and the fluid must haveroughly the same electrical potential toensure that measurement is accurateand no galvanic corrosion takes placeat the electrode.

Normally the reference electrode in thesensor or the metal pipe ensures thatthe potentials are equalised.

Reference electrodes:

Promag A:Always with reference electrode

Promag F:Optional, depending on material

Promag H:No reference electrode, as there isalways a metallic connection to thefluid.

If the reference electrode is correctlygrounded and the fluid flows throughmetallic, non-lined and groundedpiping, then it is sufficient to connect thegrounding terminal of the Promag 33transmitter housing to the potentialequalisation line in order to preventcorrosion. The connection with theremote-mounted version is made atthe ground terminal of the connectionhousing.

Caution!Danger of permanent damage tothe instrument! If the fluid cannot begrounded for operational reasons,ground disks are to be used.

Potential Equalisation for Lined

Pipes with Cathodic Protection

When the fluid cannot be grounded foroperational reasons, the measuring unitmust be installed that it is potential-free.Ensure that components of the pipingare connected to one another (copperwire, 6 mm2).

All national regulations regardingpotential free installation are to beobserved (e.g. VDE 0100).Ensure that the mounting material useddoes not result in a conductive bondwith the measuring unit and that thematerial can withstand the tighteningtorque used.

Potential Equalisation Plastic or Lined Piping

Ground disks must always be usedwith non-conductive piping materials ifcompensation currents flow through thefluid. They can irreparably damage thereference electrode within a short timedue to electrochemical corrosion.

Such conditions occur especially if:• the piping is insulated with electrically

non-conductive materials and• the piping is made of fibreglass or

PVC through which flow highly concen-trated acids and alkalis.

Equalising Currents in Ungrounded

Metal Pipes / Grounding in an Area

Technical Data Application

Instrument name Flow measuring system “Promag 33”

Instrumentfunction

Flow measurement of liquids in closed piping.Applications in measurement, control and regulation processes,for e.g. batching and dosing (> 10 s), etc.

Function and system design

Measuringprinciple

Electromagnetic flow measurement according to Faraday’s law(generation of a voltage by induction in a magnetic field).

Measuring system Instrument family “Promag 33” consisting of:• Transmitter: Promag 33 (with electronics versions HART,

PROFIBUS-PA, PROFIBUS-DP, Rackbus RS 485or EEx i)

• Sensor: Promag A (DN 2, 4, 8, 15, 25)Promag H (DN 25, 40, 50, 65, 80, 100)Promag F (DN 15...2000)

Two versions are available:• Compact version• Remote version (FS or FL version)

Input variables

Measuringvariable

Flow velocity (proportional to induced voltage, measured by twoelectrodes in the measuring tube)

Measuring range Measuring range of electronics within v = 0...12.5 m/s

The full scale value for the current output can be selected withinthe following limits (see also page 5):– Minimum full scale value at v = 0.3 m/s– Maximum full scale value at v = 10 m/s

Operable flowrange

Over 1000 : 1When the flow is pulsating, the amplifier is not overloaded above itsset full scale value even with peak velocities of 12.5 m/s.Flow is measured between 0.01...>10 m/s at the stated accuracy.

Auxiliary input The auxiliary input is only available with a “RS 485” communicationsmodule.

U = 3...30 V DC, Ri = 1.8 kΩ, galvanically isolatedConfigurable for: Positive zero return, totalizer reset, starting a batchcycle or dual range mode.

Output variables

Output signal • Current output:active, 0/4...20 mA, galvanically isolated, RL (see page 23),time constant selectable (0.01...100 s),full scale value freely selectable, temperature coefficient:typical 0.005% o.r./°C; resolution: 10 µA

• Pulse / frequency output:active/passive selectable, galvanically isolatedactive: 24 V DC, 25 mA (max. 250 mA during 20 ms), RL > 100 Ωpassive: Open Collector, 30 V DC, 250 mA

Frequency output:full scale frequency 2...10000 Hz, pulse/pause ratio 1:1,pulse width max. 2 s

Pulse output:pulse value and pulse polarity selectable,pulse width adjustable (0.05...2 s)above a frequency of 1 / (2 x pulse width) the pulse/pauseratio is 1:1

(continued on next page)

22

Output variables (continued)

Output signal(continued)

• Alarm output (Relay 1):Either NC or NO via a jumper available (factory setting: NO contact)max. 60 V AC / 30 V DC; max. 0.5 A AC / 0.1 A DC, galvanicallyisolated. Configurable for: error message (failure), empty pipedetection (EPD), failure + EPD, full scale switching, batch precontact,direction of flow, limit value 1 and overflow (v > 12.5 m/s)

• Status output (Relay 2):Either NC or NO via a jumper available (factory setting: NC contact)max. 60 V AC / 30 V DC; max. 0.5 A AC / 0.1 A DC, galvanicallyisolated. Configurable for: empty pipe detection (EPD), full scaleswitching, batch contact, direction of flow, limit value 2 and overflow(v > 12.5 m/s)
