PRODUCT RANGE The MJK product range covers a comprehensive pallet within instrumentation and monitoring of processes for aquaculture and wastewater, drinking water and process water. To create an overview of our product range, we have divided our products into categories. Each product category has its own color code and symbol. The color codes are used throughout the catalog to indicate, which products can be combined.

LOGICAL OPERATION AND NETWORK Many of our products now have PC software for configuration, control and updating purposes. The software widens the scope and applications of our products. Many of our products can communicate with other instruments or SCADA systems to make it faster, simpler and safer for you to configure from a PC. The products in the MJK instrument range communicate with each other and share a display via a network connection. For example, the display can be set up to show the individual measured values from up to four different instruments in the network or show all measurement...

RTU & CONTROLLERS [ Today, we store and log data from most processes. The quality and volume of discharged water, especially from inlets to waterworks, pump wells, aquaculture and water treatment plants are logged. We use the data to document and control processes with the aim of ensuring operating profitability yet at the same time preserving our nature for future generations. ]

CONTROLLING PUMP STATIONS CONTROLLING WATERWORKS In Scandinavia alone, more than 10,000 pump stations in operation use an MJK product to control and monitor the process. One of the major benefits of using MJK products is that the equipment always has backward compatibility. MJK controllers can be used everywhere in modern waterworks, from the raw water intake, with the filters and in pump stations. Intelligent communication solutions make it possible to link the controllers and gather data from meters all over the plant. TRIED AND TESTED TECHNOLOGY MJK supplies some of the market’s most sophisticated...

ALL-ROUND COMMUNICATION MONITOR LINK MJK controllers offer versatile communication options. You can read values on the installation site itself or via communication with a SCADA system. Monitor Link is a server-based SCADA system ideal for smaller and medium-sized applications. Many MJK instruments are supplied with Modbus, Profibus, RS232 and RS485 communication modules. The software is created to provide a simple overview, also of more complicated networks e.g. from the catchment area to a waterworks, or to a water treatment plant. Several of our control and data-logging units have PC communication,...

CONTROLLERS WITH COMMUNICATION CONTROLLERS WITHOUT COMMUNICATION In practice, there is often a need for local controllers, which have no communication or remote control functions. MJK controllers are well-known for their reliability, flexible connection and simple, logical control system.

DATABASE Chatter can send data in a text message directly to a mobile phone combined with communication from the Chatter in 3 ways: to a database, using a standard RTU protocol directly to a SCADA system or by sending e-mail. The unit can also send a text message simply to notify of an alarm. Chatter sends data to a database. From here, measurements and alarm signals can be uploaded for further processing or transmitted to a SCADA system. The database solution is ideal for systems, which have many Chatter units because an individual or several Chatter units can be reconfigured from the server....

MONITORING GROUNDWATER LEVELS CONSTRUCTION SITE MONITORING In water supply systems, Chatter is used to measure and monitor the water level in monitoring wells. Chatter is used in major construction projects to monitor the groundwater level. The example shown here is from a tunnel construction project in Malmö, Sweden. MJK supplied monitoring equipment to measure groundwater lowering at 120 water wells during the construction phase. On delivery, Chatter is built with an aluminium pipe with an impact-resistant plastic cover, into which the data logger, modem, antenna and battery are packed to form...
