Electromagnetic Measurement

MAGFLUX ELECTROMAGNETIC FLOWMETERS DELIVER VERY STABLE AND ACCURATE FLOW MEASUREMENTS OF PRESSURISED, CLOSED PIPE SYSTEMS.

With MJK's MagFlux electromagnetic flowmeter, you can measure flow in electrically conductive liquids in closed, pressurized pipe systems with great precision. MagFlux measures full accuracy at a fluctuation of 0.25% down to a speed of 0.2 m/sec. This not only ensures a high accuracy at low flow, but it also expands the flowmeter's dynamic measurement range. This is why high precision is also obtained even when measurements large areas.

MagFlux for fully running pipes has no moving parts, which offers the advantage that the flowmeter does not affect the pressure conditions of the pipe system. The modern modular design is flexible and can be used to measure many types of flow in conductive fluids. Due to the high data reliability, the flow meter is used widely to eliminate water waste due to leakage and as flow measurement of wastewater.

MJK sensors are easy to install. They are designed according to installation lengths ISO standards. To obtain highly qualified measurements, you just need 3x diameter straight pipe in the inlet direction and 2x diameter in the outlet direction. The sensor meets this goal for many of the smaller dimensions, giving you flexible installation options.

MagFlux flowmeters, converters and displays are produced in stainless steel and fiberglass-reinforced polyester, and therefore provide maximum protection against the environmental challenges faced by the equipment. Our measuring instruments cover a wide range of installation types and are developed with competitive specifications, so they can be combined in different way to meet specific requirements.

To decide which MagFlux Electromagnetic Flow Meter is the correct one for your specific purposes, please use the MagFlux Configurator.

MagFlux is used for flow measurements within wastewater. From incoming liquids with a high content of sludge to outgoing water. In many places, our MagFlux flow sensors are used to keep track of the amounts of wastewater that is moved from urban districts to larger treatment plants. Large DN measurements are often used here, such as DN1000. MagFlux is also MID certified, which means that the flow meter can be used for documentation for invoicing deliveries to or from users, or between plants, as counters cannot be reset.

The MagFlux 7200 series comes with hard rubber lining. This is especially good for liquids that contain solid elements and a certain amount of chemicals such as for example wastewater. If you need to measure liquid with corrosive chemicals or very hot liquids, we recommend MagFlux 7100 with PTFE lining.

The Magflux converter has outputs for both 4-20 mA, ModBus and ProfiBus - depending on the configuration. From the sensor, the signal can be routed up to 1000m in cables. This is convenient in larger sewage pumping facilities. A Magflux display can show data from four converters and sensors.

MagFlux from MJK is used to measure flow from boreholes to the waterworks and document the water that the borehole has delivered. Magflux is also MID certified, which means that the counter cannot be reset. MagFlux is  widely used in the network from the waterworks to the end consumer. In many countries, MagFlux is used, among other things, to detect leaks when measuring night flow.

MagFlux 7200 is used for drinking water. This model has a WRAS certificate, which is an approval for drinking water measurements in i.a. England. Magflux 7200 is often used when two waterworks exchange water. As the Magflux sensor measures in both directions, you can easily calculate an overall net result.

MagFlux sensors work well in humid environments, as it can be IP68 secured without problems. You can also choose separate mounting of the converter - up to 50 meters away from the sensor. The sensor has three electrodes built-in and comes with three-point calibration, which gives a very accurate measurement with fluctuations of just 0.25% at as low a speed as 0.2 m/sec. A Magflux display can show data from four converters.

MagFlux can be used for measuring inlet and outlet water, and even for wastewater in sludge tanks. MagFlux flow meters provide accurate measurements of water entering the tanks or of the outlet water discharged via a filled pipe system. The sensor has three electrodes built-in and comes with three-point calibration. This gives a very accurate measurement with fluctuations of just 0.25% at as low a speed as 0.2 m/sec.

The Magflux converter has outputs for both 4-20 mA, ModBus and ProfiBus - depending on the configuration. The converter can be moved up to 50 meters from the sensor. Furthermore, the signal from the converter can be carried up to 1000m to the display - this is convenient for larger aquaculture facilities. The converter can be IP68 secured and thus withstand being constantly immersed in water (max. 10 meters VS) if it is to be mounted in a very humid environment. A Magflux display can show data from four converters and sensors.

If you need to measure flow in very heated water or wastewater with corrosive chemicals, we recommend MagFlux 7100 with TPFE lining. This liner is made especially for process fluidswater. MagFlux is even MID certified, and, since the counters cannot be reset, the flow meter can be used to document invoicing of deliveries to or from users, as well as between systems,.

Magflux is supplied with electrodes in stainless steel, Hastelloy, platinum or titanium - with which almost any requirements can be met. The Magflux converter has outputs for both 4-20 mA, ModBus and ProfiBus - depending on the configuration. The converter can be moved up to 50 meters from the sensor. Furthermore, the  converter signal can be carried up to 1000 meters to the display, which is convenient for larger facilities. A Magflux display can show data from four converters and sensors.


ELECTROMAGNETIC FLOW MEASUREMENT

For accurate measurement, an MJK MagFlux electromagnetic sensor must have a filled tube.

The reduction in diameter increases the speed of the water and ensures a credible and accurate measurement.

The coning on the pipes must be mounted at least 3xdiameter before and 2xdiameter after the MagFlux sensor.

FLOW MEASUREMENT OF WASTEWATER

At this inlet to a wastewater treatment plant, MagFlux is used to measure the quantity delivered from trucks.

The measurement is used for invoicing the amount of wastewater processed.

RELIABLE FLOW DATA

These two large MagFlux sensors are mounted to measure the volume of wastewater pumped on from an underground pumping station.

Flow data from the two converters is transferred via ModBus to a more conveniently located display that shows data from both sensors.


MJK MagFlux features

HIGH PRECISION

Accordion control

MagFlux is designed to eliminate water loss and measures with a deviation of as little as 0.25% at 0.2 m/sec. Even at low flow rates the precision is top notch - just as measurements are at high speed.

Build in lengths

Accordion control

MJK flow sensors are easy to install and meet ISO standards for installation lengths. All you need is 3xdiameter straight pipe inlet and 2xdiameter outlet to obtain highly qualified measurements. The sensor itself meets this requirement for many of the smaller dimensions
