BIGboy™ Flow Meter
1
CALIBRATION
This meter has a permanent factory calibration for
measuring water. If installed and used correctly,
inaccuracies of no greater than ±5% will be obtained.
INSTALLATION
This meter may be installed in-line either horizontally
or vertically. Installation to metal connections is not
recommended. Install as follows:
1. Apply teflon tape to all fittings (customer supplied).
2. Install meter in the arrow direction of flow.
3. Hand-tighten fitting on both ends of the Flow Meter.
DO NOT
overtighten with tools, which will damage
the plastic housing.
OPERATION
Batch and Cumulative Totals
The meter maintains two totals. The batch total
may be reset to measure flow during a single use. The
cumulative total provides continuous measurement and
may not be manually reset. The batch total is labeled
as TTL1. The cumulative total is labeled TTL2.
When the cumulative total reaches a maximum reading
of 9999, it will automatically reset to zero.
Press the DISPLAY button briefly to switch between the
batch and cumulative total.
Activate the Meter
Turn the meter ON by starting water flow or briefly
pressing the DISPLAY button. The meter will display the
batch or cumulative total from last use.
Press DISPLAY briefly to display the batch total. Hold
the DISPLAY button down for three seconds to reset the
batch total to zero.
The meter is programmed to turn off automatically if
not used for about one minute.
MAINTENANCE
Proper handling and care will extend the life and
service of the meter.
Turbine Rotor
The meter is virtually maintenance-free. However, it is
important the rotor moves freely. Keep the meter clean
and free of contaminants.
If the rotor does not turn freely, apply a penetrating
lubricant on the rotor, shaft, and bearings. Remove any
debris or deposits from the rotor using a soft brush or
small probe. Be careful not to damage the turbine rotor
or supports.
Battery Replacement
The meter is powered by two AAA alkaline batteries
which may be replaced while the meter is installed.
When batteries are removed or lose power, the batch
and cumulative totals reset to zero but the factory
calibration is retained.
Batteries included.
