Omron E8FC series flow sensors

Omron’s E8FC series of flow sensors introduces dual parameter sensing, where a single meter measures the temperature of a liquid as well as its flow. The simultaneous monitoring of temperatures means more abnormalities can be detected than when only flow is measured.

Typical applications include measuring cooling water used in moulding and welding; here, the water must not only flow, it must also be below a certain temperature to be effective. Faulty or substandard products could result if either is incorrect.

The sensors are available as analog only or analog + IO Link, both with COM2 and COM3 baud rates. All models have a digital output for external alarm detection, which enables easy replacement of existing units.

The meter uses its IO Link channel to return the flow rate, temperature and a range of configurable alarm bits, set by threshold values. This allows users to monitor proceedings and perform preventive maintenance functions if needed.

A four-digit, high-luminosity, seven-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 features an ‘upside down’ mode for when the meter needs to be mounted this way.
