Electromagnetic Measurement

MagFlux Flowmeters are developed for measurements in all types of conductive liquids, including measurement of flow in drinking water, waste water, sludge and process water.

MagFlux Electromagnetic Flow Meters deliver extremely stable and accurate flow measurements in pressurized closed pipe systems, thereby decreasing water waste and eliminating non-revenue water loss.

MagFlux Electromagnetic Flow Meters for pressurized closed pipe systems.
The modular design is versatile. MJK's sensors and converters cover a broad range of applications and can be combined to meet specific requirements.
Our instruments are designed for flexibility and can be used in many types of flow measuring in conductive liquid applications.

MagFlux Flowmeters, Converters and Displays include a technically advanced enclosure made of glass-reinforced polycarbonate, offering maximum protection against harsh industrial environments.
The multilingual and user-friendly display panel has multiple mounting options and provides all instructions in clear text - no symbols or codes are used. A single display can operate up to four flow converters and sensors.

MJK MagFlux Sensors are easy to install. They are build according to the ISO-standards for installation build in lengths.

You need a straight inflow pipe which is only 3 x the diameter and a straight outflow pipe which is only twice the diameter of the flow meter. For smaller dimensions, the sensor itself – to a great extent – meets all build in lengths

MagFlux is used to measure all kinds of waste water, from very slurry liquids to outlet water.
In many areas, the MagFlux sensors are used to keep track of the amounts of waste water pumped from an urban region to a greater plant. Often seen here are the large DN sizes.
MagFlux is MID certified. This means the flow meter can be used to invoice deliveries to and from clients – or in between plant as the counter cannot be reset.
The hard rubber lining of MagFlux 7200 is working well also with the rugged elements of the waste water as well as a certain amount of chemical. For very corrosive chemicals, use the 7100 PFTE lining.
The output from the converter is RS485, and the converter can be wall mounted up to 1000m from the sensor. This is very common in larger waste water pumping facilities.
One MagFlux Display can handle four converters and sensors.

Magflux is used for measuring the flow from borings to the plant. It logs and transfers the the amount of water the water boring has delivered.
For drinking water, use MagFlux 7200. This model also holds the WRAS certificate for UK drinking water purposes
Magflux is also widely used on the network, from drinking water facilities to end-users. MagFLux is MID certified. This means the flow meter can be used to invoice water deliveries for clients – or in between waterworks.
When two waterworks are exchanging water it comes in handy that one MagFlux can calculate flow in both directions. This means that a net figure can be counted easily.
The Sensor works in moist environments. If you want the converter nearby, this can be IP68 secured or you can have a wall mounted converter and display cable connected up to 1000m.
The sensor is constructed with three electrodes, and a 3-point calibration which provides an excellent precision of only +/- 0,25% and measures as low as 0,2 m/s.
In many countries, MagFlux is used to identify leaks in the pipes by logging the night flow. You can see the diversions in consumption and estimate if there are leaks in the system.
One MagFlux Display can handle four converters and sensors.

MagFlux measures inlet and outlet water or waste water for sludge tanks.
It provides exact measurements of the water going into the tanks or outlet water when the water leaves in filled piping systems.
The sensor is constructed with three electrodes, and a 3-point calibration, which provides an excellent precision of only +/- 0,25% and measures as low as 0,2 m/s.
The 4-20 mA signal transfers data for database usage. The output from the converter is RS485, and the converter can be wall mounted up to 1000m from the sensor. This is very common in larger waste water pumping facilities.
The converter can be IP68 secured when gel potting kit is used.
One MagFlux Display can handle four converters and sensors.
MID certification allows the counted volumes to be used for documentation or invoicing. Consider this way of doing exact measuring of the wastewater on a well boat – avoid corrosion by using hastelloy electrodes for sea water

For very heated water, highly corrosive water or water containing other aggressive elements, the 7100 lining PTFE is recommended. This lining is especially created for process fluids.

The electrodes created in steel, Hastelloy, titanium or platinum, will match almost any usage.

MagFLux is MID certified. This means the flow meter can be used to invoice deliveries to and from clients – or in between plant as the counter cannot be reset.

The output from the converter is RS485, and the converter can be wall mounted up to 1000m from the sensor. This is very common in larger waste water pumping facilities.

In order to obtain the most accurate flow measurement, the MagFlux sensor needs to be fully filled with water.

This MagFlux installation in Norway shows a MagFlux with a smaller DN size than the pipe system.

This reduction increases the velocity of water in the sensor, securing valid and accurate measurements.
The reducers and the MagFlux sensor must be mounted with a min. of three times the diameter before and two times the diameter after the MagFlux sensor.

In the inlet of a Danish waste water treatment plant, the MagFlux is used to measure the inlet flow and volume pumped from tank trucks.

The measurement is used for invoicing the customer based upon the volume delivered.

The two large MagFlux sensors are mounted to measure the volume of waste water pumped from an underground pumping station in Denmark.

The flow data from the converters are transferred via ModBus to a remotely mounted display, showing data from both converters.


Features

Accuracy

Accordion control

MagFlux Flow Meters set the gold standard for precision. MagFlux Meters offer full accuracy down to 0.25% at a speed of 0.2 m/sec. This ensures optimal accuracy to measure even low rates of flow but it also expands the flow meters dynamic measuring range whilst keeping the high accuracy.

Build in lengths

MJK Flow Sensors are easy to install. They have ISO-standard build-in installation lengths. You need a straight inflow pipe which is only 3 x the diameter and a straight outflow pipe which is only twice the diameter of the flow meter. For smaller dimensions, the sensor itself – to a great extent – meets all build in lengths requirements.
