ifm SM8000 Magnetic-Inductive Flow Meter, G 1, 0.2-100 l/min

ifm SM8000 Magnetic-Inductive Flow Meter, G 1, 0.2-100 l/min

The ifm SM8000 is a magnetic-inductive flow meter for conductive liquids from 0.2 to 100 l/min (0.01 to 6 m³/h) with a G 1 external thread (DN25). Compared with the smaller SM6004, it adds a totaliser function, a preset counter and a wider choice of outputs: switching, analogue (4 to 20 mA or 0 to 10 V), pulse and IO-Link. Accuracy is ±(0.8 % of measured value + 0.5 % of final value).

It also measures medium temperature and can monitor it with its own switching point. Seven Star LLC supplies the SM8000 in Oman and the GCC as an independent supplier in Muscat.

SM8000 technical specifications

The table lists the values published by the manufacturer for the SM8000. Where a parameter has several operating modes, the headline value is shown; the full parameter list is in the manufacturer documentation.

How the SM8000 works

The SM8000 is a magnetic-inductive flow meter: a magnetic field is applied across the pipe, and a conductive liquid moving through the field induces a voltage proportional to its velocity. Because nothing protrudes into the flow, there are no moving parts to wear and the pressure loss is very small. A temperature sensor in the same unit adds medium temperature as a second measured value, shown on a four-digit LED display and available on the outputs. The liquid must be conductive; the conductivity and viscosity limits stated in the table must be respected.

Where the SM8000 fits and related parts

The SM8000 is the larger and more flexible sibling of the SM6004. Use it on main cooling branches, dosing lines or process water where batch quantities (totaliser or preset counter) are required, and where the PLC can read IO-Link process data. The similar housing dimensions (54 mm diameter, 110 mm length) make mechanical replacement simple, but the G 1 thread means the adapters differ.

Selection and ordering checklist for the SM8000

Work through the points below before you confirm the order, so that the SM8000 you receive is the one your machine or plant needs.

• Confirm flow range 0.2 to 100 l/min and pipe size to G 1 (DN25)
• Check conductivity of at least 20 µS/cm and viscosity below 70 mm²/s at 40 degrees Celsius
• Check the 16 bar rating and the 10.4 bar value for CRN applications
• Decide whether you use the totaliser, the preset counter or the pulse output
• Select the output type: current, voltage, switching or IO-Link

The manufacturer lists this article under the type designation Magnetic-inductive flow meter, SMR11GGXFRKG/US-100. The article number SM8000 is the reference to quote when ordering, and the type designation is useful for technicians who compare the label on an installed unit.

Installation, commissioning and maintenance

Install the meter with the inlet and outlet pipe lengths shown in the table so that the profile is stable, and keep the pipe full at all times; air pockets cause unstable readings. Flat seals are used on the thread, so make sure the sealing surfaces are clean and the adapters fit the pipe. In cooling circuits and process water loops place the meter where bubbles will not collect at the top. Commissioning involves setting the display unit, the analogue range and the damping value, and then comparing a reading against a reference flow if the application is critical. Keep the M12 connector dry and tight, and flush the line if scale or magnetic debris could build up.

Keep the same pipe-length rules as the smaller meter (3 x DN inlet, 1 x DN outlet) and make sure the pipe stays full. The counter reset input allows batch-wise operation from a PLC. Because the meter has several output modes, document the final parameter setting on the machine, so a replacement sensor can be set up identically.

Typical applications in Oman and the GCC

Typical duties in Oman and the GCC include cooling water circuits to process equipment, chemical dosing and water treatment skids, filling and batching, and monitoring of recirculation flow through heat exchangers. Temperature monitoring on the same device helps in chilled water loops.

Flow meters in the region often sit in cooling and utility circuits that run year-round at high ambient temperature. Scale, bubbles and dirt are the main sources of error, so strainers upstream and a full pipe at the measuring point matter more than any setting in the menu.

SM8000 compared with related ifm types

The table places the SM8000 next to neighbouring types in the same application group, so you can see whether a sibling would suit the job better.
