2.6 SYSTEM STORAGE AND MAINTENANCE RECOMMENDATION
1. Always store the system in its carrying case when not in use.
2. Before long-term storage of the system, blow all excess water from the flow meter turbine
assembly and wipe the flow meter stem assembly dry with a clean cloth. Do not put any
lubricants on the turbine assembly. Oil based lubricants will damage the flow meter’s o-ring
seals.
3. If storing the system for long periods of time, remove the 9 volt battery from the Display
Module and store it separately.
4. The flow meter’s hot tap adapter should be pushed completely down over the turbine
assembly and locked so that the turbines are protected when moving the system to a new
location or when storing the system.
5. The flow meter turbines, bearings and shafts can be cleaned using a 30 percent white
vinegar to 70 percent tap water solution. An old toothbrush can be used to lightly brush
around the bearings. Rinse with clean water and blow off excess water before storing.
2.6 FLOW METER INFORMATION
ONICON’s D-1401 / D-1402 Insertion Turbine Flow Me-
ter measures the velocity of flowing liquids by counting
the frequency at which the blades of a rotating turbine
pass a fixed electrode. Circuitry within the flow meter
electronics enclosure then converts the rotational rate to
a frequency output.
