Measuring System Fields of ApplicationWith the Promag 30 (Model '99) flow-meter most liquids can be measuredprovided they have a minimum conduc-tivity of 5 S/cm, e.g. acids, alkalis, pastes, pulps, drinking water, waste water,
sewage sludge, milk, beer, wine, mineral water,
yoghurt, molasses, etc.
A minimum conductivity of 20 S/cmis required for measuring demineralisedwater.

Promag 31 F PTB approval for custody transfer
with cold water and wastewater (eitherfor approval or approved for custodytransfer)
Heat measurement approval,Swiss certification to OIML R72/R75
Promag 31 H PTB approval to DIN 19217 (OIML 117)

Function Measuring PrincipleAccording 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 patentedIntegrated 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 30 (Model '99)The Promag transmitter converts themeasured values coming from thesensor into standardised output signals.The following outputs are available forthese signals: Current output
(full scale value freely selectable) Pulse output
(pulse value freely selectable) Status output:
Indication of system or processerrors
Indication of flow direction Auxiliary input:
Positive zero return Totalizer reset
Promag 30 also has the followingfeatures: Empty Pipe Detection (EPD) detects
and 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).
Ue = B L vQ = v A
Ue = induced voltageB = magnetic induction (magnetic field)L = distance between electrodesv = flow velocityQ = volume flowA = pipe cross-section

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). Thehigher installation expense is normallybalanced by the lower sensor cost.
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 re
