Series IEFS Insertion Electromagnetic Flow Sensor
Brand: Dwyer Instruments, LLCThe Series IEFS Insertion Electromagnetic Flow Sensor comes in brass or stainless steel allowing it to handle a wide range of pressures and temperatures, as well as a variety of available saddle fittings, Series SDF, to fit pipe sizes 3 to 24˝.
The IEFS-1XX has an isolation valve which allows hottap installation.
Additional options for this flow meter include adapter fittings and a reverse flow output. The Series IEFS is great for “dirty” water applications or any application where mov
ing parts may be an issue.
PRINCIPLE OF OPERATION
The IEFS is a liquid flow meter that uses a magnetic field to measure flow. As conductive fluids flow through the magnetic field, a voltage is generated which is measured and translated into a pulse frequency output signal.
This signal can then be used with the Series BAT to produce a 4 to 20 mA Analog signal, or the Series RTI to display rate and total.
Features- Long life cycle and less frequent maintenance with no moving parts to wear or break and electrodes that discourage fouling
- Unaffected by change in temperature, density, viscosity or concentration
- Pulse output for use with a variety of displays and controllers for remote reading
- Easy meter mount display and transmitter accessories for local indication and Analog 4 to 20 mA output
