AquaMaster 3 FET200
Electromagnetic flowmeter Transmitter 3 Electrical Installation
20 OI/FET200–EN Rev. I
3.3.6 Pressure Transducer (Optional)
Optional pressure transducer cables are available for a range of pressures and cable lengths.
3.3.7 Anti-tamper Protection
In some applications, such as those covered by the Measuring Instruments Directive (MID) 2004/22/EEC or
OIML R49 the flowmeter can be sealed to prevent unauthorized changes to the meter settings and
configuration. A read-only switch / link is used (see Fig. 3.12) to prevent login through any communication
means and modification of any parameters on the AquaMaster3.

Caution. Use only the pressure transducer supplied with the transmitter. Use of other pressure
transducers requires alteration of the pressure span and zero factors in the transmitter.
