Introduction
The SITRANS F US SONOFLO
®
ultrasonic flowmeter type SONOKIT mounting set is used for
installing one set of ultrasonic transducers type SONO 3200 in existing pipes made of steel or
concrete.
This manual only describes the SONOKIT installation in empty unpressurized pipes. When
installing SONOKIT
in pressurized pipes (hot tapping), please contact Siemens Flow Instruments
for further instructions.
SONOKIT is designed for measuring the flow velocity of liquids in full pipes. Satisfactory function
of the ultrasonic flowmeter depends on a low attenuation of the medium and a well-defined and
stable flow profile.
The making of an ultrasonic flowmeter by means of the SONOKIT is divided into 4 steps:
1. Calculating and marking the transducer holder position
2. Installing the transducer holders
3. Marking the sensor geometry
4. Entering the sensor geometry into SONO 3000 (theoretical calibration)
To ensure optimum performance of the measuring equipment it is essential that the following
instructions are followed.
Location
The SONO 3200 sensor can be installed both
indoors and outdoors, even in exposed
surroundings.
The sensor is suitable for media and ambient
temperatures from –50°C to +100°C, the high-
temperature version from –40°C to +200°C. The
temperature range is stated on the data plate on
the transducer. The enclosure rating is IP 67 or
better. Optionally, the SONO 3200 is available
with IP 68.
In case of large temperature differences be-
tween the medium and the environment the
sensor must be isolated to avoid 2-phase flow
which will result in inaccurate measuring re-
sults.
The space requirements around the pipe for
retrofitting a SITRANS F US SONOFLO
®
ultra-
sonic flowmeter type SONOKIT are given be-
low:
Note:
The above dimensions are minimum values.
Different space requirements apply when retrofitting takes place in pressurized pipes or when the
transducers are exchanged under pressure.
1. Introduction
Potential Hazards
The ground wire must always be connected to the ground terminal in accordance with the
diagram.
