Stainless steel electromagnetic flow meter with IO-Link up to 140 °C

Electromagnetic flow meter developed to measure and monitor small to medium flows of conductive liquids in pipelines. The stainless steel body and PEEK lining allow process temperatures up to 140 °C. The electronics provide two analogue outputs, pulse, frequency or alarm outputs, IO-Link and a control input, and are available in compact or remote versions.

Features

• Measuring ranges from 0.01…1 l/min up to 1.5…650 l/min
• Accuracy ±(0.8 % of reading + 0.5 % of full scale)
• Pressure up to 16 bar, temperature up to +140 °C
• Connections G ¼, G ½, G ¾, G 1, G 2 and 2" NPT, with various adapters
• Integrated PT1000, bidirectional measurement and grand, part and resettable totalisers
• Rotatable TFT display, operable with gloves
• Batching function: output 1 configured as NPN/PNP/PP switching output and output 2 as control input

Operating principle

According to Faraday's law, a conductive liquid passing through the sensor's magnetic field generates a voltage proportional to the flow velocity. Electrodes in contact with the medium transmit this voltage to the amplifier, which calculates the volumetric flow from the pipe cross-section. The measurement is independent of density, viscosity and temperature, provided the medium has a minimum conductivity.
