HydroLogic 01N31GM Quick Manual

Flow Meter (High Capacity) for BIGboy™
Batteries included.

IMPORTANT NOTICE

Use this meter for water only. Do not use to meter fuel
or chemicals.
This meter is not legal for trade applications.
The meter is very sensitive to electrical "noise" and
may not operate correctly if located near some
electrical equipment.

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 or at the end of the hose adjacent to the
nozzle, if present. Installation to metal connections is
not recommended. Install as follows:
1. If necessary, remove nozzle from hose.
2. Apply pipe sealant to all threaded connections.
3. Attach meter to hose with arrow on outlet port
pointed in the direction of flow.
4. If necessary, attach nozzle to meter
5. Hand tighten the meter at the housing ends. Do not
use a wrench or similar tools to tighten the meter
housing. The plastic housing could be damaged.

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.
CAUTION: Blowing compressed air through
the turbine assembly could damage the rotor.
