6. CHECK AND MAINTENANCE

Visually check the following items.
・ Whether flow transmitter cover screws are loose.  Tighten.
・ Whether cable glands are loose.
・ Whether the detector stainless steel belt is loose. ⇒ Tighten.
・ Whether received wave is abnormal (LED lit red). ⇒ Check whether piping is filled or not. Remove bubbles or foreign
・ Whether temperature is abnormal (LED lit red).
・Is there any dirt or dust on the main unit?

Reapplying grease

If using high-temperature grease as an acoustic coupler, reapply the high-temperature grease to the noise damping frame
and sensor unit transmission surface approximately every 6 months for a short-term type and approximately every 2 years
for a long-term type.
Note) When using high-temperature grease (long-term type), pay attention to the following:
・Use the gloves attached to the product to apply the grease. If the grease gets on your skin, wash it off with plenty
of soap and water.
・Before using the product, refer to the grease precautions and safety data sheet attached to the product.
・Reapply the grease if the pipe temperature drops below -15°C when the equipment is shut off for a long time.
Note) Perform the work while making sure that water does not splash on the acoustic coupler.
Note) Store the acoustic coupler indoors in a cool and dark place. Since ultraviolet rays and foreign object contamination
may cause deterioration, store it after securely closing the lid.

6.1. Daily Check

 Tighten.
matters, if mixed in measurement pipe. Also check if detector
mounting and wiring are set up properly.
Check at "6.3.1.2 Checking the LED lit in red (1)".
⇒ Check whether the resistance temperature detector is broken, or
whether the temperature exceeds the input range.
Check at "6.3.1.2 Checking the LED lit in red (2)".
⇒ Dampen a soft cloth with water and wipe it off. The display of the
main unit scratches easily. Therefore, be careful when wiping it off.
Note) Do not clean using volatile substances such as benzine and
thinner. The paint may peel off.
