●Product handling
Installation
Tighten to the specified tightening torque.
If the tightening torque is exceeded the mounting screws and brackets may damaged.
If the tightening torque is insufficient, the product may be displaced and the mounting screws may come loose
(Refer to page 14 ”Mounting and Installation”.)
Ensure that the FG terminal is connected to ground when using a commercially available switch-mode
power supply.
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, or lift the product by the lead wire. (Tensile force 49 N or less)
Hold the product body when handling, to prevent damage, failure or malfunction
When connecting the piping, hold the specified part of the body with a spanner.
Hold the product body when handling, to prevent damage, failure or malfunction
Any dust left in the piping should be flushed out 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 product label for installation and piping.
Do not mount the body with the bottom facing upwards.
Retention of air can cause inability to measure accurately.
Do not insert metal wires or other foreign matter into the piping port.
This can damage the sensor causing failure or malfunction.
Never mount a product in a location that will be used as a foothold.
The product may be damaged if excessive force is applied by stepping or climbing onto it.
If there is a risk of foreign matter entering the fluid, install and pipe a filter or the mist separator at the

Wiring
Do not pull the lead wires.
In particular, never lift a product equipped with fitting and piping by holding the lead wires.
Otherwise damage to the internal parts can result, causing malfunction.
Avoid repeatedly bending or stretching the lead wire, or placing heavy loads on it
Repeated bending stress or tensile stress can cause damage to the sheath, or breakage of the wires.
If the lead wire can move, fix it near the body of the product.
The recommended bend radius of the lead wire is 6 times the outside diameter of the sheath, or 33 times the
outside diameter of the wire insulation material, whichever is larger.
Replace any damaged lead wire with a new one.
Wire correctly.
Incorrect wiring can damage the product.
Do not perform wiring while the power is on.
Otherwise damage to the internal parts can result, causing malfunction.
Do not route wires and cables together with power or high voltage cables.
Otherwise the product can malfunction due to interference or noise and surge voltage from power and high voltage
cables.
Confirm proper insulation of wiring.
Poor insulation (interference from another circuit, poor insulation between terminals, etc.) can lead to excess
voltage or current being applied to the product, causing damage.
Keep wiring as short as possible to prevent interference from electromagnetic noise and surge voltage.
Do not use a cable longer than 30 m.
Wire the DC (-) line (blue) as close as possible to the power supply.
When analogue output is used, install a noise filter (line noise filter, ferrite element, etc.) between the
switch-mode power supply and this product.
