3.1 Maintenance and Inspections
Preventative maintenance and periodic inspection is important to ensure long life and proper
functioning of the ultrasonic flowmeter.
3.1.1 Transducer and Main unit maintenance and inspection
Although maintenance of transducers or main unit is generally not required, be aware of the
following items.
(1) Cleaning
Do not use any chemical liquids like thinner to clean up flowmeter systems. Please use dry-soft
cloth for cleaning up the main unit or other items.
(2) Warning labels
Inspect and clean the warning labels to ensure readability. Contact representative in your area of
the manufacturer when warning labels have dirtied or peeled off.
(3) Avoid subjecting transducers to shocks or impacts.
Do not subject transducers to impact from hard objects, dropping, or other handle harshly in any
other manner.
(4) Transducers are designed considering to measure outside during the rain. But, please be noted
that avoiding the environment such as exposed to wind and rain for a long time would be highly
appreciated. Please wipe moisture off promptly after used in wet atmosphere.
In the following cases, the waterproof performance will not be retained. The connector is not
correctly connected. You can not use it in water (non-submergible).
(5) Although the transducers may be deteriorated in performance, outward will not be changed.
If you may doubt its performance, please contact the nearest representative. To compare
ultrasonic signals, deterioration will be identified.
(6) Transducers are designed considering to measure outside during the rain. But, please be noted
that avoiding the environment such as exposed to wind and rain for a long time would be highly
appreciated. Please wipe moisture off promptly after used in wet atmosphere.
In the following cases, the waterproof performance will not be retained. The connector is not
correctly connected. Rubber cover of the battery and USB (main unit right side) is not correctly
obtained. The screw is loose. You can not use it in water (non-submergible).
3.1.2 Life of components
Certain components of the main unit have operational life expectancies. Periodic check of these
components is recommended. Please contact the nearest representative in your area when any
component replacement is required.
(1) LCD
The contrast of the LCD may darken when this life is exceeded. (Contrast is adjustable. Please
refer to Chapter “
1.2.2 (2) LCD indication & key panel assignment
(p.1-12)”.)
Generally LCD
life may be shortened if it is exposed to direct sunlight, high temperature or high humidity.
(2) Lithium battery (for logging and date-time backup)
The lithium battery which is used for date-time and logged file backup, requires replacement
approximately every 5 years.
When battery is fully-discharged, logged file will be deleted, date-time back to default if power is
off.
In case of battery discharged, warning message comes up at start-up self-check.
