DANGER!
The device must be grounded in accordance with regulations in order to protect personnel
against electric shocks.
• A shielded 2-wire copper cable is used as the field current cable. The shielding MUST be
connected in the housing of the flow tube and transmitter.
• The outer shield (60) is connected in the terminal compartment of the flow tube directly via
the shield and a clip.
• Bending radius of signal and field current cable: ≥ 50 mm / 2"

4.6 Grounding the flow tube
CAUTION!
There should be no difference in potential between the flow tube and the housing or protective
earth of the transmitter!
• The flow tube must be properly grounded.
• The grounding cable should not transmit any interference voltages.
• Do not use the grounding cable to connect any other electrical devices to ground at the same
time.
• The flow tubes are connected to ground by means of a functional grounding conductor FE.
• Special grounding instructions for the various flow tubes are provided in the separate
documentation for the flow tube.
• The documentation for the flow tube also contain descriptions on how to use grounding rings
and how to install the flow tube in metal or plastic pipes or in pipes which are coated on the
inside.
4.7 Connecting the power supply
DANGER!
• To protect operators from electrical shock, during installation the cable for the power
supply must be run with sheathing insulation up to the mains cover. The insulated individual
wires have to be only below the mains cover!
• If there is no mains cover or if it has been lost, the 100...230 VAC device may only be
operated from the outside (with a magnet pencil) while closed!
• The housings of the devices, which are designed to protect the electronic equipment from
dust and moisture, should be kept well closed at all times. Creepage distances and
clearances are dimensioned to VDE 0110 and IEC 60664 for pollution severity 2.
Supply circuits are designed for overvoltage category III and the output circuits for
overvoltage category II.
• Fuse protection (IN ≤ 16 A) for the infeed power circuit, and also a separator (switch, circuit
breaker) to isolate the transmitter must be provided.

•
The device must be mechanically safe and mounted in compliance with the regulations.
Remove the magnet pencil and keep it on a save place (is only valid for the display version).
The power connections must have been made in compliance with the regulations.
The electrical terminal compartments must be secured and the covers have been screwed
on.
• Check that the electrical operating data of the power supply are correct.
• Switching on the power.
5.2 Starting the transmitter
The measuring device, consisting of the flow tube and the transmitter, is supplied ready for
operation. All operating data have been set at the factory in accordance with your order
specifications.
When the power is switched on, a self test is carried out. After that the device immediately
begins measuring, and the current values are displayed.

two times the "pulse width" values. This filter is called "median" filter.
This filter allows a better suppression of pulse shaped disturbances (particles or air
bubbles in very noisy environment).

8 TECHNICAL DATA
IMT30A
8.1 Measuring principle
An electrically conductive fluid flows inside an electrically insulated pipe through a magnetic
field. This magnetic field is generated by a current, flowing through a pair of field coils.
Inside of the fluid, a voltage U is generated:
U=v*k*B*D
in which:
v = mean flow velocity
k = factor correcting for geometry
B = magnetic field strength
D = inner diameter of flowmeter
The signal voltage U is picked off by electrodes and is proportional to the mean flow velocity v
and thus the flow rate Q. A signal transmitter is used to amplify the signal voltage, filter it and
convert it into signals for totalizing, recording and output processing.

8.5 Measuring accuracy
Every electromagnetic flowmeter is calibrated by direct volume comparison. The wet calibration
validates the performance of the flowmeter under reference conditions against accuracy limits.
The accuracy limits of electromagnetic flowmeters are typically the result of the combined effect
of linearity, zero point stability and calibration uncertainty.
