Dwyer Series IEF insertion electromagnetic flow transmitter

Click2Contact

The Series IEF insertion electromagnetic flow transmitter is an adjustable insertion flowmeter featuring electromagnetic technology that measures fluid velocity in addition to providing several continuous signal outputs.

The series is specifically designed to offer high performance paired with simple installation and use. Each unit is adjustable to fit pipe sizes from 102 to 914 mm, and offers several output options including selectable BACnet MS/TP or Modbus RTU communications protocol over 2-wire RS-485 in addition to the standard analog, frequency and alarm outputs.

Outputs include analog: 4–20 mA, 0–5 V, 0–10 V or 2–10 V (display selectable); pulse/frequency: 0–15 V peak pulse, 0–500 Hz or scalable pulse output (display selectable); and two alarm outputs (empty pipe detection or minimum/maximum velocity, and reverse flow indication).

The measurement range of the series is 0–6 m/s with an accuracy of ±0.5% of reading at calibrated velocity, ±1% of reading from 0.6 to 6 m/s and ±0.006 m/s at <0.6 m/s.

The operating ambient temperature range is -29 to 71°C, while the process temperature is up to 121°C. Wetted parts are made from 316 stainless steel.
