1.1 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 70 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 different differential
pressure ranges, i.e. 12,5 – 50 and 50 – 200 mbar for the S2/S02 / S2SS/S02SS
and 22 – 550 mbar for the S25/S05 / S25SS/S05SS, depending on the desired
and ordered flow range. The same goes for our models; V1/V1SS/D2/D2SS
and V15/V15SS/D5 and D5SS. Due to the working principle of the
instrument, it is of outmost importance that the installation instructions
(chapter 2) are followed carefully in order to get the proper function of the
instrument.
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 it also
contains all electrical connections for input and output.
The covers for the flow monitors are available in two materials. Powder
coated aluminum (S2 / S25 / S02 / S05) and stainless steel (S2SS / S25SS /
S02SS / S05SS).
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 Control Units S02, S05, S02SS and S05SS have a local readout and S2, S25,
S2SS and S25SS are also equipped with two independent adjustable alarms
