SENSOR EXCITATION
This voltage shall not be used to supply the flowmeter's electronics, converters
etc., as it will not provide adequate sustained power! All energy used by the
flowmeter's pick-up will directly influence the battery life-time. It is strongly ad-
vised to use a 'zero power' pickup such as a coil or reed-switch when operating
without external power. It is possible to use some low power NPN or PNP
output signals, but the battery life time will be significantly reduced (consult
your distributor).
NOTICE
8.2 V; Only available when external power is connected.
