Sensor Mounting - Fuji Electric FSJ Instruction Manual

Apply acoustic coupler to the sensor transmission surface.
Mount the sensor with "+" tag on the upstream side of the sensor mounting bracket, and mount the sensor with "-" tag on
the downstream side of the sensor mounting bracket.
After fitting the V-groove in the sensor to the sensor mounting bracket holder pin, tighten the screws, and press the sensors
against the pipe. After tightening the screws with torque of 2 Nꞏm using a hexagonal torque wrench (M6 screw, width across
flat of 5 mm), secure with the lock nuts.
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.
