2.1Intended Use
The volume flow sensor is used for measuring and displaying the flow rate or pressure and outputs it pro-
portionally as an electrical voltage from 1 to 5V on an analog output.
This device has been designed, developed and constructed solely for industrial and commercial use. Pri-
vate use is excluded.
The volume flow sensor is built in accordance with the latest standards of technology and is delivered in a
safe operating condition. However, hazards may occur during use.
Intended use includes observing the technical data and the installation and operating instructions in this
manual.
2.2Non-Intended Use
Schmalz accepts no liability for damages caused by the use of the product for purposes other than those
described under "Intended Use."
Non-intended use includes the following:
• Use in potentially explosive atmospheres
2.3Personnel Qualification
Unqualified personnel cannot recognize dangers and are therefore exposed to higher risks!
1. Only instruct qualified personnel to perform the tasks described in these operating instructions.
2. The product may only be operated by persons who have undergone appropriate training.
3. Electrical work and installations may only be carried out by qualified electrical specialists.
4. Assembly and maintenance work must only be carried out by qualified personnel.
2.4Warnings in This Document
Warnings warn against hazards that may occur when handling the product. The signal word indicates the
level of danger.

5.1Installation Instructions
• Do not use near a surge voltage generated area. Solenoid lifters, high fre-
quency Induction furnaces and motors, etc. can generate high surge volt-
ages, if using near the sensor will cause the internal circuit components to
deteriorate and cause damages.
• Sensors can not withstand lightning strikes. The product is CE compliant, but
can not resist surge voltage of lightning strikes, take measures to avoid
lightening strikes in the system.
• Do not use in an environment where sensors could be splashed by water or
oil. Enclosure rating is IP40, please avoid water or oil splashed environment
to prevent adversely effects.
• Do not use in an environment subject to large temperature cycling. Internal
components of the sensor will be affected adversely by large heating/cool-
ing cycles other than ordinary changes in temperature.
• Do not mount the product in locations where it is exposed to radiant heat.
This could result in damage and/or malfunction.
• Ensure the flow direction of the fluid. Follow the flow direction indicator
for installation and piping.
• Flush out all dirt and dust by air blow before connect the piping to the sen-
sor.
• When installation, do not drop, hit or apply excessive shock (100m/s2). Inter-
nal damage can cause malfunction even if the housing appears to be un-
damaged.
• Do not install multiple products in close proximity. The heat generated from
each product could cause the temperature to rise and change the character-
istics of product or deterioration of the plastic parts. Please position the
products 10mm apart from each other.
• Hold the sensor body when installing. The tensile strength of the cable is
24.5N and apply excessive pulling force can cause damage to the sensor.
NOTE
The pressure or flow rate exceeded the specified range
The sensing element may be damaged
4Check the regulator and flow adjustment valve before introducing the fluid.
The sensing element cannot measure properly if foreign matter adheres to it.
On the inlet side, be sure to install an air filter below the filtration level of 10µm.

When measuring the pressure of the inlet side, install a throttle valve or solenoid valve on
the outlet side.
When measuring the pressure of the outlet side, install a throttle valve or solenoid valve on
the inlet side.

Do not mount the sensor in a place that will be used as a foothold. The product may damage if sit or step
on it accidentally.
The LCD display may be difficult to see at certain angles.
The sensor can be installed horizontally or vertically, but the flow rates may change because of the instal-
lation way of the product or piping.
The tightening torque for screws should be under 0.5 ±0.1Nm.
