WARNING! – Danger through improper usage!
1.6 Package contents
Please verify that all listed parts are undamaged included in
the delivery and check for consistency specified in your
order:
- digital pressure gauge
BAROLI
- mounting instructions
2. Product identification
The device can be identified by its manufacturing label. It
provides the most important data. By the ordering code, the
product can be clearly identified. For identification of the
firmware the program version will appear for about 1 second
in the display after starting up the device. Please hold it
ready for inquiry calls.

The manufacturing label must not be removed from the
device!
3. Mechanical installation
3.1 Mounting and safety instructions
WARNING!
Install the device only when depressurized
and currentless!
WARNING!
This device may only be installed by
qualified technical personnel who has read and
understood the operating manual!
!
Handle this electronic precision measuring device
carefully in packed as well as in unpacked condition!
!
The device must not be subject to any changes or
modifications.
!
The device may not be thrown!
!
To avoid damaging the diaphragm, remove packaging
and protective cap only directly before starting up the
device. A delivered protective cap must be stored!
!
Place the protective cap on the pressure port again
immediately after disassembling.
!
Handle the unprotected diaphragm very carefully - it is
very sensitive and may be easily damaged.
!
Do not use any force when installing the device to
prevent damage of the device and the plant!
!
The display and the plastic housing are equipped with
rotational limiters. Please do only rotate the display or
the housing within the limit.
Take note that no inadmissibly high mechanical
stresses occur at the pressure port as a result of the
installation, since this may cause a shifting of the
characteristic curve or the demage.
In hydraulic systems, position the device in such a way
that the pressure port points upward (venting).
Provide a cooling line when using the device in steam
lines.
3.2 General installation steps
- Carefully remove the pressure measuring device from
the package and dispose of the package properly.
- Then go ahead as detailed in the specific instructions
below.
3.3 Installation steps for DIN 3852
DO NOT USE ANY ADDITIONAL SEALING MATERI-
ALS, LIKE YARN, HEMP OR TEFLON TAPE!
- Check to ensure the proper groove fitting of the o-ring
and additionally to ensure no damage to the o-ring.
- Ensure that the sealing surface of the taking part is
perfectly smooth and clean. (R
Z
3.2)
- Screw the device into the corresponding thread by
hand.
- If you have a device with a knurled ring, the transmitter
has to be screwed in by hand only.
- Devices with a spanner flat have to be fully tightened
with an open-end Devices with a spanner flat have to
be tightened with an open-end wrench (G1/4": approx.
5 Nm; G1/2": approx. 10 Nm; G3/4": approx. 15 Nm;
G1": approx. 20 Nm; G1 1/2": approx. 25 Nm).
-
The indicated tightening torques must not be ex-
ceeded!
3.4 Installation steps for EN 837
- Use a suitable seal, corresponding to the medium and
the pressure input (e. g. a cooper gasket).
- Ensure that the sealing surface of the taking part is
perfectly smooth and clean. (R
Z
6.3)
- Screw the device into the corresponding thread by
hand.
- Tighten it with a wrench (for G1/4": approx. 20 Nm; for
G1/2": approx. 50 Nm).
-
The indicated tightening torques must not be ex-
ceeded!
3.5 Installation steps for NPT
- Use a suitable seal (e. g. a PTFE-strip).
- Screw the device into the corresponding thread by
hand.
- Tighten it with a wrench (for 1/4" NPT: approx. 30 Nm;
for 1/2" NPT: approx. 70 Nm).
-
The indicated tightening torques must not be ex-
ceeded!
3.6 Installation steps for dairy pipe
- Check to ensure that the O-ring fits properly into the
intended groove in the mounting part.
- Center the dairy pipe connection in the counterpart.
- Screw the cup nut onto the mounting part.
- Then tighten it with a hook wrench.
3.7 Installation steps for Clamp and Varivent
- Use a suitable seal corresponding to the medium and
the pressure input.
- Put the seal onto the corresponding mounting part.
- Center the Clamp or Varivent
connection on the fitting
counterpart with seal.
- Then fit the device with a suitable fastening element (e.
g. semi-ring or retractable ring clamp) according to the
supplier’s instructions.
3.8 Installation steps for connecting flanges
- Use a suitable seal corresponding to the medium and
pressure input. (e. g. a fiber gasket).
- Put the seal between connecting flange and counter
flange.
- Install the device with 4 resp. 8 screws (depending on
flange version) on the counter flange.
3.9 Positioning of the display module
The display module of the pressure gauge is rotatable so
that clear readability is guaranteed even on unusual
installation positions.
4. Supply / changing the batteries
The digital pressure gauge is supplied by two 3.6 V-lithium-
batteries (Type 1/2 AA). Stored values/parameters are also
kept after changing the batteries.
If the symbol for low batteries is indicated in the display, it is
necessary to replace them as soon as possible with two
new ones of the same type in order to ensure a good
readability of the values. This has only to be done in
switched-off condition.
The battery case is located under the black, circular plastic
cap on the top of the housing. To change the batteries go
ahead as follows:
