General Information

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 reliability. 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 measuring 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 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 Eletta Flow Monitor models S2/S02 and S25/S05 will give you an accuracy 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 following standards;

Threaded connections in BSP or NPT from 15 mm (

/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 construction. 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

1.1

5041D2E18

equipped with two independent adjustable alarms (micro switches) which can be set for low and high flow alarm. The readout has a scale, which shows you the ordered flow range with a multiplier as a standard. The standard scales have the following designations; for S2/S02 the scale goes from the number 4 to 8 (1:2 turndown). This is the value that you have to multiply the small multiplier (sticker) figure at the bottom of the scale with, in order to read the actual flow in the values you have ordered i.e. liters/min, m3/hours, USGPM. etc. (also shown at the bottom of the scale) For the S25/S05, the scale goes from 1 to 5 and hence, this is the value you use together with the multiplier at the bottom of the scale, to read the actual Flow through the Monitor.

The Control Unit can also be fitted with a special ordered scale (direct reading scales) as an option, for example; l/min, m3/h, USG/min etc. for easy reading and then you have no multiplier at the bottom of the scale.

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).

Accuracy: <+/–5% F.S (full scale) within 20-80 % of the chosen Flow range

<+/–10% F.S.(full scale) within 100% of the chosen Flow range

The accuracy stated is achievable if the installation instruction is followed given in this manual. It is recommended that you always choose the Flow Range of the Flow Monitor so that the normal flow is in the middle of the Monitor Flow Range. Make sure that the expected alarm set points are within the chosen flow range. For example: If you have a flow of 110 l/min maximum and the normal Flow is at 90 l/min, chose the Eletta Flow Monitor S2 with a Flow Range of 60–120 l/min. This will give you the highest accuracy since your flow is in the middle of the Monitor Flow Range and give you a lower pressure loss.

Repeatability: < 2 %

Pressure: Max:16 bar, (232 PSI), higher test pressure as an option.

Min: A line pressure of apx.: 0,7 – 1,0 bar (10 – 14,5 PSI) is required for proper operation.

Temperature: Control Unit

–20°C to 120°C ( –4°F to 250°F), optional The lower temperature is not valid for Monitors equipped with FPM soft parts. FPM is limited to –5 °C (23 °F). Higher process temperature with remote installation of Control Unit (separate mounting, see section 2.4) These temperature limits are valid for models S2 and S25 (with micro switches) Temperature limit for S02 and S05 is –20°C to 120°C (–4°F to 250°F). Pls note the FPM soft part remark above, which is valid also for S02/S05 models.

Pipe Section: The pipe sections are equipped with spacers (holding the orifi-

ce plate) made of Polyamide plastic (PA) material and they can handle liquid/gas temperature up to 150 °C (300°F). For higher process temperature, we recommend to use the stainless steel pipe section, which has no spacers.

Installation

Unpacking

We appreciate that you have decided to purchase our Products and we would like to ask you to begin the installation by checking your delivery against the Packing List. Please make sure to check the box for external damages before opening. If you find external damages, which have also led to damages to the Flow Monitor inside, you should contact the forwarder/shipper to claim replacement (or the cost of replacement). Check the Monitors’ identification tag against your purchase order to make sure you have got the right parts with the right specifications.

All Monitors are individually packed in plastic bags and put into the box either two by two or individually in each box. The plastic bag is to prevent foreign particles to get inside the Pipe Section, which could prevent proper function of the Flow Monitor after the installation.

The box is made from recycled environmental friendly material and we kindly ask you to deal with the waste material in a way that will have as little impact on the environment as possible.

Procedures before Installation

Note!!! Before any installation or maintenance work, disconnect all electrical power!

Please check that you are going to mount the Monitor at the lowest point in the piping system if you are measuring liquids and at the highest point if you are measuring gases. Also check if the planned flow direction in the system matches the one indicated on the Monitor. There is a red flow direction arrow on the outside of the pipe section (not the Stainless Steelmodels which have a marking engraved on the side). If you find this to mismatch, we refer to section 3.4 ”Change of Flow Direction”, to adjust the internal flow director in order to match the desired flow direction. Change of the flow direction on the 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 representative 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.

If you are using the separate/remote execution i.e. Pipe Section and Control Unit installed in different locations, please check the plastic hoses for any da-

2.1

2.2

5041D2E18

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 that the piping is not under pressure from flow of liquid/gas!

The pipe section can be installed in any desired direction, vertically or horizontally or angular and the direction arrow on the pipe section denote the direction of the flow. It is very important that the pipe section is mounted with the correct direction, as the function of the Flow Monitor otherwise will be prevented. The piping shall be rigid and free from vibrations and hoses connected directly into the Monitors should be avoided as much as possible. If you have weak piping we advise you to use the M6 mounting holes (only on GL - series) on the backside of the pipe section, to fasten the pipe section to a wall or a rigid bracket. The straight runs before and after the Monitor should not be too short, in order to avoid disturbances, which can cause the Monitor to show incorrect values. We recommend giving at least 10 - 15 diameters upstream and 5 diameters downstream. (Please see Fig. 1)

The reasons for this procedure is to achieve a stable flow profile inside the pipe and by doing so, get a true reading. Please be aware of the fact that it is practically impossible to predict when the flow is stable after disturbances in the piping, so this must serve as a guideline only. The straight runs must be
