Product handling

Installation

Tighten to the specified tightening torque.
If the tightening torque is exceeded the mounting screws, brackets and the product can be broken. Insufficient
torque can cause displacement of the product from its proper position and the looseness of the mounting screws.
(Refer to "Mounting and Installation" on page
23 .)

Be sure to ground terminal FG when using a commercially available switch-mode power supply.

Do not use in a place subject to heavy vibration and/or shock.
Otherwise damage to the internal parts can result, causing malfunction.

Do not drop, hit or apply excessive shock to the product.
Otherwise damage to the internal parts can result, causing malfunction.

Do not pull the lead wire forcefully, not lift the product by pulling the lead wire.
(Tensile force 49 N or less)
Hold the product (plate of the main piping) by the body when handling to prevent damage.

For piping of the product, hold the piping with a spanner on the metal part of the piping (Piping
attachment).
Applying the spanner to other parts may lead to damage to the product.
In particular, do not let the spanner come into contact with the M8 connector.
The connector can be easily damaged.

Eliminate any dust left in the piping by air blow before connecting the piping to the product.
Otherwise it can cause damage or malfunction.

Refer to the flow direction of the fluid indicated on the model number plate or the body for installation
and piping.
Residual air can cause errors in measurement accuracy.

Avoid piping in which the piping size of the IN side of the switch changes suddenly.
If the piping size is reduced sharply or there is a restrictor such as a valve on the IN side, fluid velocity distribution in
the piping will be disturbed, leading to improper measurement.
Therefore, the above-mentioned piping should be connected on the OUT side.
If the OUT side is opened, or flow rate is excessive, cavitations may be generated, which may result in improper
measurement.
As a measure against this, it is possible to reduce the cavitations by increasing the fluid pressure.
Take action such as mounting an orifice on the OUT side of the switch, and confirm that there is no malfunction
before handling.
If the orifice of the OUT side is fully closed to operate the pump, the switch may malfunction due to the effect of
pulsation (pressure fluctuation). Ensure that there is no malfunction before usage.

Do not insert metal wires or other foreign objects into the flow path.
Such actions can damage the sensor causing failure or malfunction.

Never mount the product in a location that will be used as a scaffold.
The product may be damaged if excessive force is applied by stepping or climbing onto it.

If the fluid may contain foreign matter, install and connect a filter or mist separator to the inlet.
The adherence of foreign matter to the vortex generator or detector can cause errors in measurement accuracy.
A filter of approx. 40 mesh is recommended.

Design and install the application so that the fluid detection path is always full.

If the product is mounted vertically, let the liquid flow from bottom to top.
Trapped air bubbles can cause errors in measurement accuracy.
(If the fluid detection path is always filled with liquid, there will be no problem.)
Please be aware that water droplets may cause early deterioration/damage, particularly if the product is installed
vertically or upside-down.

Do not apply excessive rotation force to the flor switch monitor.
Rotating the display with excessive force will damage the end stop.

The manifold body is made from resin. Do not apply load directly to the product during installation or
piping.
This may cause damage, breakage and/or water leakage of the product.
