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.
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.
If the meter display becomes dim or blank, replace the batteries as follows:
1.
Remove the four Phillips-head screws from the face of the meter and lift the faceplate from
