COMPACT, robust, reliable and cost-effective – these are important characteristics of instrumentation in industrial automation.
That’s according to global instrumentation pioneer Krohne, which said its new AF-E 400 was specifically designed for industrial automation and is best in its class in terms of temperature range, accuracy, pressure drop and flow range.
“Its unique compact sensor design makes this electromagnetic flowmeter perfect for use in tight spaces and for parallel installations in a variety of conductive liquid applications e.g. in cooling lines of welding equipment, bending machines and robots or on chemical dosing skids,” the company said in a statement.
“The AF-E 400 features best-in-class accuracy in every flow range, allowing optimal processing in automation.”
It added that the round bore reduction of the sensor makes the flowmeter more resilient in terms of increased pressure, ensuring high accuracy over a wide pressure and temperature range. Its integrated temperature measurement also eliminates the need for an additional sensor.
“The AF-E 400 was developed with tight spaces in mind and guarantees maximum flexibility when it comes to installation. Due to the special design of its magnetic circuit, field strength and electronics, this mag meter can be positioned in extreme proximity to one another (as close as 2 mm / 0.08″). It can thus be mounted in parallel without interference.”
Krohne said it examined some of the common issues with products in this segment and translated them into improvements across the board. AF-E 400 features for example the highest temperature capability. The continuous use at +90°C/+194°F liquid temperature allows its operation in very demanding cooling and hot water applications.
“The latest insights at Krohne in magnetic field design and signal conversion enable the highest accuracy without adding costs. Furthermore, the combination of tight seals and laser welding guarantees high IP65 and IP67 ingress protection.”
The integrated temperature measurement eliminates the need for an additional sensor. This minimises the intrusion points in the pipe and provides more data from the process.
Self-diagnostics is another top feature, with the meter continuously monitoring potential issues like low supply voltage and incorrect parametrisation, as well as flow range exceedance or short circuit on any of its outputs.
“The factory settings of the device make plug-and-play installation possible. For easy connection the common M12 connector is used.”
