1 General Information

1.1 Description

The D-series Eletta Flow Monitor are used to measure and control flows of liquids and gases in

threaded pipes with sizes DN15-DN40 and flange fitted pipe sizes DN15 to DN500.

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. 500-2000 mmH2O (49-196 mbar) for the D2 and 220-

5500 mmH2O (22-539 mbar) for the D5, depending on the desired and ordered flow range and the

same goes for our models; V1 and V15, S2 and S25 and R2 and R5. Due to the working principle of

the instrument, it is of utmost importance that the installation instructions are followed carefully in

order to get the proper function of the instrument.

The Instrument mainly consists of two parts 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.

D-series is available with four different types of pipes; Threaded GL/GSS and FA/FSS for flanged

fitting.

1.2 Overview Control Unit

The Control Unit mainly contains the diaphragm housing and two circuit boards (the display circuit

board and the power circuit board). The mechanical movement on the diaphragm lever created by

the differential pressure in the pipe is acting on the rubber diaphragm in the same way as our other

mechanical Flow Monitors. The lever connected to the diaphragm is acting on a linear potentiometer

placed on the power circuit board in the Control Unit. As our Monitors have a linear function

between the differential pressure and the flow, the circuit board will give you a linear flow output of

4-20 mA, HART protocol, pulse or 200-1000 Hz frequency. The difference to our mechanical V and S-

series is that in the D-series there is no mechanical linkage acting on micro switches, as the unit lacks

them, only the potentiometer giving infor-

mation to the circuit board. Since there

are fewer moving parts and less

mechanical linkage in the Control Unit,

the D-series will give you a higher

accuracy than V and S-series.

In order to get the unit to work properly with good accuracy, it is very important that the unit is

installed correctly according to the installation instruction, see chapter 2 “Installation”.

1.3 Overview Pipe Section

The Pipe Section is assembled in-line with the process pipe and the Control Unit is fitted on top of

the Pipe Section. It is also possible, for example when measuring a too hot media, to install the

Control Unit separated (using either steel pipes or tubes) from the Pipe Section, see chapter 2.5.

There are four different types of Pipe Sections; GL, GSS, FA and FSS. All Pipe Sections except FSS

contains an exchangeable Orifice Plate. The FSS Pipe Section do not contain an exchangeable Orifice

Plate since the shaft and orifice makes one integrated unit.

1.7 Type Plate

Each Eletta Flow Monitor wear a Type Plate with technical data and specifications for the specific

Flow Monitor. The Type Plate is located on the top of the Control Unit shown as below.

Always check that the information on the Type Plate corresponds to what you have ordered.

The Type Plate states the following:

•Type: Model type of the Flow Monitor.

For example: D5-GL15.

•Range: Flow range of which the Flow

Monitor has been manufactured.

i.e. what the Orifice Bore has been

calculated for.

•Liquid: The media of which the Flow

Monitor has been manufactured.

For example: Water, Oil, Air, etc.

•Model: The article number of the Flow

Monitor.

•No: The serial number of the Flow

Monitor.

•Temp: The operating temperature range

allowed for the Flow Monitor.

•Max Pressure: The maximum operating

pressure allowed for the Flow Monitor.

•Protection Class: IP-classification of the

Flow Monitor (International Protection

Marking).

•Std: Pipe standard of the Pipe Section.

For example: DIN PN16/ANSI, BSP/NTP.

•CE marking and year of manufacturing.

1.8 Specifications

Flow range

Liquids: 0,4-25 000 l/min, depending on pipe size

See chapter 8 “Measuring Ranges” for a table of our standard flow

ranges for water and oil

Gases: will be calculated according to application

Flow measuring range

(Turn Down)

D2-model: TD of 1:2 (50-100% Flow Range)

D5-model: TD of 1:5 (20-100% Flow Range)

Accuracy

±2% F.S. (Full scale)

Accuracy is stated as per reference and under ideal conditions i.e.

straight runs, temperature, pressure, viscosity and density. It is

recommended that you always chose the flow range of the Flow

Monitor so that the normal process flow is in the middle of the

Monitor Flow Range. For example: If you have a flow of 110 l/min

maximum and the normal flow is at 90 l/min, choose the Eletta Flow

Monitor D2 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 will also give you a lower pressure loss

Pressure

Pressure class: PN16 / ANSI 150 lbs

Max static pressure: 16 bar (232 PSI)

Min static pressure: Line pressure of approximately 1 bar (14 PSI) is

required for proper operation

2 Installation

2.1 Unpacking

Before installation, we kindly ask you to perform the following steps:

1) Check that there are no external damages to the outer packaging. If there are damages, check to

see if the Flow Monitor has been damaged. If there is a transportation damage on the Flow Monitor,

please contact your forwarder.

2) Check that the delivered parts correspond to the Packing list. Also check that the information on

the Type Plate corresponds to what you have ordered. The Type Plate is located on top of the

Control Unit, see chapter 1.7 “Type Plate”.

The packaging material is made of recycled environmental friendly material, and we kindly ask you

to deal with the material in a way that will have as little impact on the environment as possible.

2.2 Preparations

Before installation, we kindly ask you to perform the following steps:

1) Eletta recommends that you choose a correct position for installation of the Flow Monitor in your

pipe system. The following table serves as a guideline.

2) Check that the planned flow direction in your pipe system corresponds to the flow direction of the

Flow Monitor. The flow direction is indicated by a red arrow that is mounted on the GL/FA Pipe

Section. On the GSS/FSS version there will be an engraved arrow on the Pipe Section. If there is a

mismatch of the flow direction, we refer to chapter 3.2 “Change of Flow Direction” for instructions

on how to adjust the internal flow direction selector (GL/FA) to match the desired flow direction. It is

not possible to change the flow direction on the GSS/FSS version without ordering a new Pipe

Section, this is because the flow direction channels are fixed for the specific flow direction and

cannot be reversed.
