KOBOLD’s latest MIM electromagnetic flowmeters is capable of precise dosing of even the smallest batch quantities

KOBOLD’s latest MIM electromagnetic flowmeters is capable of precise dosing of even the smallest batch quantities, even with small nominal diameters, providing precise readings ​​in a minimum of space

Worldwide unique flowmeter combining IO-Link with remote version design                                                                                                                                    

Be in the pharmaceutical industry, in water treatment or in food production; if conductive media such as cooling water is added to a process, magnetic-inductive flow meters are usually installed for monitoring purposes, particularly in the context of dosing where the measuring flow meters must possess precise response times, and should also be easy to configure, otherwise incorrect dosing or insufficient repeatability will occur.

Although there are already many accurate devices for small and medium flow rates in the market place, they are often limited in functionality or lack flexibility at the instalation stage. KOBOLD  provides these features as standard with its flowmeter duo, models MIM and MIS.

Due to the extensive options for on-site programming, these instruments are suitable for cross-industry use, particularly for dosing applications. Configurable optical buttons can be used to display parameters such as flow rates or temperatures.  A changing colour system in the display also warns of limit violations. Since the MIM model is the first variant produced in a remote version, in which the display and electronics are not integrated in the sensor unit, the flow meter can be used for media temperatures up to +140 ° C.

For reference, `Magnetic-inductive‘ flow meters work without moving parts, unlike rotating vane flow meters, and for this reason they can be used in a wider range of applications, and are very resistant to wear. As a result, these devices have proven to be effective in measuring the flow of conductive media such as water, pulps and pastes, juices, and emulsions. However, this wide range of applications also leads to very different installations, since the measuring instruments are used in a variety of  industries and processes, for example; the nominal size of the connected pipes, possible orientation during installation and integration into certain process chains, such as dosing of media during the coating of tablets or during coolant supply, influence the choice of a suitable flow meter, particularly in the context of dosing processes where the measuring instruments must offer the possibility of programming intermediate values ​​in order to document the quantities, and to avoid inaccurate dosing. In addition, the display should be multi-line and clearly visible so that the plant engineers are warned in good time before exceeding a limit value. Often however, flowmeters only meet some of these requirements, and often at the expense of usability.

For this reason, KOBOLD  developed the products MIM and MIS with care and attention to the detail that industries have been calling for; universal flow meters incorporating IO-Link to meet Industry 4.0 requirements (if or when required), which are suitable for almost any measuring situation and guarantee high programming freedom in addition to good response times of sometimes less than 100 milliseconds. On the one hand, the numerous functions such as temperature measurement or dosing are performed accurately, which can be set in just a few steps in the program menu with the hot key buttons. On the other hand, the robust and flexible design enables simple and clear installation, even in tight-fitting pipe systems.

Installation in extreme conditions
The two models are made entirely of durable materials, the MIM in stainless steel. In addition to the temperature measurement function, which only MIM has, the devices differ mainly in relation to the pipe sizes at which they are used. While MIS has flanged process connections; suitable for sdtandard nominal sizes DN 80 (3“) and DN 100 (4“), the MIM has threaded process connections, though tri-clamp is available as an option, and can be used for very small nominal pipe sizes and covers an even larger measuring range; depending on the nominal size – upwards of 30 ml/min. The flow meters have two individually configurable outputs that can act as a pulse, alarm or analogue output, depending on the setting. This makes them much easier to integrate into different processes or auxiliary circuits. The colour multi-display can also rotate digitally in 90° increments, making them ideal for both vertical and horizontal installations – the display being independent of the position of the connections, so when purchasing there’s no need to specify the flow direction – a convenient  advantage.

The response time has now been improved to facilitate more precise dosing quantities. In addition, different subsets can be programmed via the menu in order not to have to navigate awkwardly with each new setting through the menu. The display has also been extended to so-called hotkeys.  With this feature, the desired dosage can be conveniently selected by optical buttons on the home screen. The desired dosing process can be started and stopped via an external control input, and, the quantity can also be changed via MIM /MIS at any time.

In a recent tablet coating application, precisely measured quantities with a very good response time were critical.  To ensure that this possibility is also available for hot media and also in temperature-controlled environments such as cooling water circuits, KOBOLD is offering for the first time a remote version. Unlike conventional devices, the media-contacting unit only contains the sensor.

The entire electronics, the control and display, are housed separately and connected via a cable at a safe distance to the sensor unit on the pipe. As a result, even temperatures up to +140 ° C are safe and the flow meter can work trouble-free because the electronics remain protected.

Basic building block for every measurement project
The flexibility of this flow meter family is also reflected in the user guide and the range of functions. Almost all settings can be comfortably done on the display via four optical buttons. Functions such as partial counter display, temperature measurement or maximum flow can also be applied to the mentioned hotkeys in order that you do not have to constantly navigate through multiple control levels in the menu. This can also be done with a glove, as the buttons have different sensitivity levels. The multi-line display offers a better overview than comparable compact devices and can also display the corresponding unit, or other information in addition to the measured value. This clarity is further enhanced by the multicolor of the display: For example, the color changes when a certain flow rate has been reached. As a result, the user also sees from a distance when for example, a certain amount has been dosed or a limit has been exceeded.
