Description
The Eletta Flow Monitor is used to control and measure flow of liquids and
gases in pipes from size 15 mm to 500 mm (larger pipes as an option). They
have been manufactured for over 65 years and are well known for its reliabili-
ty. They are used where operational safety demands, efficient supervision and
rugged installation is needed, all over the world. Eletta Flow AB in Sweden is
certified according to ISO9001 and ISO14001.
The Eletta Flow Monitor is based on the proven and dependable differential
pressure principle, using interchangeable orifice plates for different measu-
ring ranges. The Flow Monitors are working with two different differential
pressure ranges, i.e. 50 – 200 mbar for the S2/S02 and 22 – 550 mbar for the
S25/S05, depending on the desired and ordered flow range. The same goes for
our models; V1 and V15, D2 and D5 and R2 and R5. Due to the working prin-
ciple of the instrument, it is of outmost importance that the installation instruc-
tions (chapter 2) are followed carefully in order to get the proper function of
the instrument.
The Eletta Flow Monitor models S2/S02 and S25/S05 will give you an accu-
racy of +/–5% F.S. (Full Scale) if installed in the right way. (See chapter 1.2
“Specifications”, for complete information)
The Instrument consists of two parts mainly i.e. the Pipe Section and the
Control Unit. The Pipe Section is the part that is to be mounted in the process
pipe and the Control Unit is mounted directly (standard) or remote on/to the
Pipe Section. The Control Unit is giving you the Flow information and also
contains all electrical connections for input and output.
The Pipe Sections are available in different process connections with the fol-
lowing standards;
Threaded connections in BSP or NPT from 15 mm (
1
/2”) to 40 mm (1
1
/2”)
depending on the chosen material of construction.
Flanged (wafer) connection from DN15 /PN16 (ANSI 1/2”/150 lbs) to DN
500/PN16 (ANSI 20”/150lbs ) depending on the chosen material of construc-
tion. The DIN-standard flanged units are colored blue, the ANSI-standard
units are colored green (>50 mm < 100 mm) for easy recognition in the field.
The Control Units S02 and S05 have a local readout and S2 and S25 are also
