Page 5: General Information
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;... -
Page 6: Specifications
The only flow difference between the S2/S02 and S25/S05 is the turn down of the flow range i.e. the S2/S02 has a 1:2 turn down (for example; 50 –100 l/min) and the S25/S05 has a turn down of 1:5 (for example; 20 – 100 l/min). - Page 7 ” – 20”) for FSS-models Alarm/ Contacts: S2 and S25 have 2 (two) micro switch SPDT contacts, inde- pendently adjustable within the ordered Flow range. S02 and S05 has no micro switch contacts included; only a dial for local indication of Flow.

Stainless Steel Pipe Sections (FSS/GSS) is not possible in the field without ordering a new Pipe Section and we kindly ask you to contact your local re- presentative or Eletta Flow AB, Sweden for help. Check that the pipe section has the right threads or the right flange standard to match your piping or counter flange. -

mages or holes that can prevent proper function. The plastic hoses should not be used in temperatures over 90ºC (194 ºF). If your application temperature exceeds this temperature/pressure, we recommend to use copper or stainless steel tubing, depending on the compatibility to the measured gas or liquid (see section 2.4) Installation of the Pipe Section Note!!! Before starting to install the Pipe Section, please make sure... -
Page 12: Separate Mounting Of The Pipe Section And Control Unit
Control Unit Sometimes separate mounting of the Pipe Section and the Control Unit is re- quested due to vibrations, high temperature or lack of space. As the Eletta Flow Monitor is using the differential pressure caused by the orifice plate... - Page 13 ports up to the Control Unit, it is also possible to separate the Monitor (Fig. 2) from the Pipe Section -GL/FA into two parts. The pressure is then lead through either plastic hoses or metallic tubing depending on the liquid, pressure and temperature.

Page 14: Installation And Changing The Control Unit
Installation and changing of the Control Unit As all Eletta Flow Monitors are designed in sections to achieve a modular and versatile Flow Monitor, there is a possibility to upgrade/rebuild them and ad- ding other features to your already installed Monitor, by changing the Control Unit or Pipe Section. - Page 15 Pipe Section, without any on-site adjustments or calibration.

0.96 ∆ρ and 0.51 ∆ρ can be expected. Example: For the Eletta Flow Monitor S2-GL15 with a flow range of 10 - 20 l/min, the following example can be used for how to calculate the ∆ρ... - Page 17 10,2 mm 16,0 mm ⇒ This gives β = 10,2/16,00 β = 0,6375 and (1-β ) = 0.594 Furthermore, in order to use this β−value in the above formula, we need to de- termine the ∆ρ . We can either use the ”Actual Pressure Drop Graph” (fig. (apd) 4) for an approximate value or for intermediate values we can use the formula below the graph (fig.

Page 22: 3.4 Change Of Flow Direction
3.4 Change of Flow Direction Empty the pipe system so that it is un-pressurized and has no flow! At the time of ordering, you must specify in which direction the Flow Monitor shall be mounted i.e. from which side is the flow entering the Pipe Section and how you would like to read the scale. -

3.4.2 Flow Direction Selector (until December 2012) Change of Flow Direction For GL and FA models there are two flow direction selectors to choose from, the ”R” and the ”L” selector. For GL-models, first empty the pipe system so that it is un-pressurized and For mounting directions according to alternative A, C and F (see fig. -
Page 24: Change Of Dial Orientation
Change of Dial Orientation As the Eletta Flow Monitors are not limited to a certain mounting position in the piping system, the large visible dial can be mounted in several positions to suit the application. (please refer to fig. 7). If you need to change the orienta- tion in the field, please do as follows;... -
Page 25: Trouble Shooting
Eletta Flow Monitors work with two different ∆ρ’s i.e. on the V1 and S2 units the ∆ρ is always maximum 2000 mm H2O (196 mbar) and for the V15 and S25 units, the ∆ρ is always maximum 5500 mm H2O (539 mbar). -
Page 26: Electrical Connections
2000 mmH2O (196 mbar) on the S2/S02series with a blocked orifice, the pointer should reach the last digit (8 for the S2/S02) on the front scale and if you have a direct reading scale installed, the pointer should reach the end value. -
Page 27: Spares
We refer to section 7 where you can find an exploded drawing showing all replaceable components included in the Flow Monitor. If you have installed the Eletta S-series Flow Monitor in a very critical appli- cation, we recommend you to have a complete identically precalibrated Control Unit on stock, as it will only take removal of four bolts to change this. -
