ifm SA5000 Calorimetric Flow Sensor, M18 thread, IO-Link

The ifm SA5000 is a calorimetric flow sensor that measures flow velocity and medium temperature at the same time. It is optimised for water, glycol solutions, air and oils, can be used at up to 100 bar and from -20 to 90 degrees Celsius, and carries a probe that is 8 mm in diameter with 45 mm installation length. The process connection is an M18 x 1.5 internal thread, and the housing can be rotated for best display orientation.

Outputs include switching, analogue (4 to 20 mA), frequency and IO-Link. Seven Star LLC supplies the SA5000 in Oman and the GCC as an independent supplier.

SA5000 technical specifications

The table lists the values published by the manufacturer for the SA5000. Where a parameter has several operating modes, the headline value is shown; the full parameter list is in the manufacturer documentation.

How the SA5000 works

The SA5000 uses the calorimetric principle: one element in the probe tip is heated and a second element reads the medium temperature. The faster the medium flows past the probe, the more heat it carries away, and the electronics translate that difference into flow velocity. Because the sensor measures flow and temperature at the same time, one device can supply both a flow switch signal and a temperature value. The medium selection in the menu adapts the evaluation to water, glycol, oil or air, and the relative mode lets you tune the response to the actual installation.

Where the SA5000 fits and related parts

The SA5000 is a flow monitor rather than a metering device: it excels at proving that flow exists, or has dropped, in cooling water, lubrication or air circuits. For quantity measurement and totalising use the SM8000 (liquid) or SD6500 (compressed air). In relative mode the sensor needs no calibration to the pipe, which makes it quick to commission.

Selection and ordering checklist for the SA5000

Work through the points below before you confirm the order, so that the SA5000 you receive is the one your machine or plant needs.

• Confirm media: water, glycol, air or oil (low-viscosity oil up to 40 mm²/s at 40 degrees Celsius)
• Check the operating pressure up to 100 bar and medium temperature of -20 to 90 degrees Celsius
• Check the mating fitting for the M18 x 1.5 thread and probe length
• Decide on relative or absolute operating mode
• Select output usage: switching, analogue, frequency or IO-Link

The manufacturer lists this article under the type designation Flow sensor, SAD10XDBFRKG/US-100. The article number SA5000 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

Insert the probe into the pipe or fitting so that the tip sits in the middle of the flow with the stated installation length, orient it as the documentation describes, and tighten the process thread within the allowed torque. Allow a straight run before the sensor so the flow profile is stable. For commissioning, choose the medium, run the system at normal flow and teach the switch point, then confirm the response by throttling the flow. Deposits on the probe tip reduce sensitivity, so include it in cleaning rounds on dirty circuits, and re-check the setting after any change in medium temperature.

Install the probe so the sensor tip is in the flow, at the stated installation length of 45 mm, and keep a straight run of pipe. Establish the switch point in relative mode by running the system at normal flow and teaching the sensor, then verify by reducing the flow. Pay attention to the temperature gradient, since the sensor reads the medium temperature as well.

Typical applications in Oman and the GCC

Cooling water in compressors, gearboxes and heat exchangers, lubrication lines on rotating equipment, and compressed-air or process-air monitoring are the usual tasks. In the GCC, loss-of-flow protection on cooling circuits prevents costly overheating, and the high pressure rating allows the sensor in hydraulic and lube oil systems.

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.
