INSTALLATION
3.1 GENERAL INSTALLATION GUIDELINES
Prior to the installation of the 8175 ultrasonic level transmitter, a clear mounting
location for the product must be determined.
●The level transmitter or sensor types 8175 / 8170 are designed for
liquid level measurement. It is the user responsability to test the
functionality of the device for any other material such as powders,
granuals etc.
●The 8175 ultrasonic level transmitter or sensor must be installed
perpendicular to the process medium.
●Ensure a minimum distance of 30 cm between the level of the fluid
and the sensor is respected.
The tank or vessel should be surveyed to locate potential obstructions which
may interfere with the beam cone. Such obstructions may include: fill pipes and
streams; mixers and agitators; tank side walls and rungs.
3.1.1 Beam cone diameter
The ultrasonic level transmitter type 8175 generates 8 pulses per second which is
emitted from the base of the transducer. As the pulses leave the transmitter, they
expand to an 8°beam angle until they are reflected back via the process medium.
To determine the maximum diameter of the beam cone for the application select the
maximum length (L) from the table below.

INSTALLATION
3.2 INSTALLATION
The ultrasonic transmitter or sensor may be installed through the tank top via a
standard G 2“ (NPT) fitting or equivalent tapped flange according to the type of level
transmitter.
Steps for successful installation:
●Before installation of the transmitter or sensor ensure that the fitting has
been tested for leaks and the threads are not damaged or worn. If a
damaged fitting is evident a new fitting should be installed.
●When installing the transmitter or sensor ensure that a proper seal is
obtained between the fitting and transmitter via the use of an appropriate
sealant or gasket.
●When securing the transmitter or sensor to the fitting, only
tighten by hand!
●Be careful not to overtighten the transmitter in the fitting.
Shaft mounting
If the transmitter or sensor 8175 is installed on a shaft, it
must not be higher than 400 mm for a diameter of 100 mm,
or 250 mm for a diameter of 80 mm.

3.2.1 PANEL VERSION INSTALLATION
For installation and insertion of the panel version follow the instructions on the
enclosed delivery film and as follows:
1. Put gasket on the cover and place the complete unit in the cut-away panel.
2. Screw the spacer bolts onto the panel fixing screws .
3. Insert the cable clips , to secure the various cables (power supply, outputs,
sensor) of the transmitter, onto the plate .
4. Fasten the plate with the screws onto the bolts , tightening the locking
washers .
The level transmitter in a wall-mounted version has 4 fixing holes at the corners of the
enclosure. Remove the white blanking strips and the cover to access to fixing holes .

●Use cables with a temperature limit of 80°C minimum.
●For normal operating conditions the measuring signal can be transmitted by a
simple cable of 0.75 mm2 cross section.
●The line must not be installed in combination with carrying lines with a higher
voltage or frequency.
●If a combined installation cannot be avoided, a minimum space of 30 cm (1 ft)
or shielded cables should be adopted.
●When using shielded cables observe faultless grounding of the shield.
●For EMC purposes the earth must be connected via the earth lug on the side of
the enclosure to a good local earthing point.
●The cable diameters for the PG versions must respect the following:
Compact: between 6-12mm and with a doubler 6mm
Wall mounted: between 4-8mm (PG‘s not used must be blanked off).
●In case of doubt, always use shielded cables.
●The power supply must be regulated - section 6.1.
●Do not open and wire the transmitter with the power supply
connected.
●It is obligatory to put security devices close to the transmitter, on :
Power supply : 18-32VDC - 250mA fuse and interrupter
115/230VAC - 5A fuse and interrupter
Relay : 10A fuse max. and a circuit breaker (depending
on the application).
