4220 Flow Meter
Section 3 Installation
3-7
Teledyne Isco offers a special optional connect cable to power the
flow meter from a separate battery. Mount the battery securely,
in an upright position, so it will not inadvertently tip over, or
be at risk of having its cable pulled off.
CAUTION
Be sure of proper polarity before attaching clips to the battery.
Never attach the flow meter to a source of unknown polarity or
voltage. If in doubt, check with a reliable DC voltmeter. Never
attach the flow meter directly to an AC power source of any
voltage under any circumstances. Charge the battery in accor-
dance with the manufacturer's instructions.

nently in other installations, such as treatment plants, at your
option.
3.3.1 Carrying Handle To help you carry and install the flow meter, a handle is provided
in the accessory package.
