Flow sensors have been used throughout industry for many years.
However, Omron’s new E8FC series introduces dual parameter sensing, in which a single meter measures the temperature of a liquid, as well as its flow.
The simultaneous monitoring temperatures means many more abnormalities can be detected than when only flow is measured.
A typical application includes measuring cooling water used in moulding and welding. In order to be effective in these applications, the water must not only flow, it must also be below a certain temperature. Faulty or substandard products could result if either is incorrect.
Three different models are available, analogue only or analogue + IO Link (both with COM2 and COM3 baud rates). All models have a digital output for external alarm detection, which allows for easy replacement of existing units.
The meter uses its IO Link channel to return the flow rate, temperature and a host of configurable alarm bits, set by threshold values. This allows users to keep a close eye on proceedings and even perform preventative maintenance functions if required.
A four-digit high luminosity 7-segment display on the meter shows flow rate, temperature or percentages of what’s expected. It also has a large indicator that changes colour to alert users of potential flow and temperature problems.
As the meter often needs to be mounted into a small or awkward space, it can be rotated up to 330° on its mounting.
The display also has an “upside‑down” mode for when the meter needs to be mounted this way
