Eletta’s differential pressure Flow Monitors are extremely well suited for rugged industrial environments.

Eletta Flow AB

The company started its operations in the late 1940s. Later a unique design of the mechanical lever enabled Eletta to obtain a patent for its products. This design is still today the foundation of the Eletta product range, with the exception of the newly developed M-series. 
Eletta Flow’s strong reputation is based on robust design, longevity and precise deliveries. The Flow Monitors are based on the well-established differential pressure principle and are extremely well suited for rugged industrial environments.

Eletta Flow’s customers require high quality products that provide accurate information. Over the years Eletta Flow has grown into a highly international company with an export share of over 85 percent. Production is exported all over the world and we have appointed distributors in most European countries, Australia, South Africa, USA, Japan, Brazil, China and India.
Eletta Flow produces a range of flow monitors with different characteristics due to their basic design: paddle, variable area or different kinds if differential pressure (DP) executions. 

The DP flow monitors and meters are the most important in the product range, making up approximately 90 percent of total production. All the mechanical and electro-mechanical flow monitors have the well proven Eletta proprietary design and robust construction.

Eletta Flow Monitors

The Eletta Flow Monitors type; V-, S-, R-, A- and D-series are based on the proven and reliable differential pressure principle, using interchangeable orifice plates for different measuring ranges. They are available for threaded connections DN 15 - 40 and flanged connections DN 15 - 400 and in different material of construction such as bronze, painted cast iron and stainless steel.
They come in two measuring ratios, 1:2 and 1:5, which is indicated by the designation of the models. Flow ranges are available from 0,4 l/min to 25 000 l/min.

The V1 and V15 are basic models without local indication and one micro switch set-point. It is adjustable within the  flow range of the monitor. They are very robust, e.g insensitive to magnetic fields, and well suited for rough industrial applications.
The S2 and S25 models have a large and easy readable dial of 130 mm which is clearly visible even in a harsh and dusty industrial environment. They have two micro switch setpoints. They are independently adjustable within the measuring range and they can be set for high- and lowflow alarms.

The S-series is also insensitive to magnetic fields.

The principle of measuring flow with an orifice plate,creating a differential pressure which corresponds to the flow, is combined with a new smart pressure sensor arrangement – The M-series.

The M-series is simple, rugged and reliable and shows the possibilities of differential pressure flow metering. The M3 is an expansion of the Eletta range, it is a compact, versatile and programmable electronic flow meter. All parameters are accessible through a standard computer interface and the flow rate remotely read via a standard 4 - 20 mA output.

The software enables you to choose between three possible modes of operation: Gas flow, liquid flow or differential pressure.
It is available in three pressure classes; 10, 25 and 50 bar in either brass or stainless steel. Pipe sizes from DN 15 - 500 and the turndown is 1:10

The A2 and A5 models have a local bargraph style indicator showing the flow as well as a 4 –20 mA signal output linear to the liquid flow. In addition to this, they are equipped with two independent adjustable set-point relays for setting alarms within the whole measuring range.This model is ideal for combining the rugged and reliable mechanical construction of the Eletta Flow Monitor with an analog signal output. This design gives a highly repeatable output signal and excludes the need to use more expensive accurate flow meters.

They use the same pipe sections as the R -, S- and V-series.

S-series

The S2 and S25 models have a large and easy readable dial of 120 mm which is clearly visible even in a harsh and dusty industrial environment. They have two micro switch set-points which are independently adjustable within the measuring range and they can be set for high and low flow alarms, for example.

D Series

The D2 and D5 Flow Monitor is the most recent model with microprocessor based electronics and back lit digital display. The display is possible to rotate 90 degrees (electronically) which makes it possible to install the monitor both vertically and horizontally in any piping system. The D2 and D5 is equipped with a 4 - 20 mA output signal as well as local alarms. A linearization possibility of the flow curve is built in and can be programmed by the user. Also included is a re-settable flow totalizer. In order to conveniently set up a flow system at dry conditions, a simulation mode for the analogue and frequency output signal can be activated.
