The UniMag series of magnetic flowmeters consists of a UniMag flow sensor and a 4411e Magnetic Flowmeter Transmitter.

4411e Overview

The UniMag series of magnetic flowmeters consists of a UniMag flow sensor and a 4411e transmitter.

The 4411e uses an innovative and patented Pulsed Hybrid method of coil excitation to create an ultra stable flow signal having a signal to media noise ratio up to 50 times higher than other magmeter technologies. As a result, the 4411e offers a clean and powerful bidirectional signal with unsurpassed fast response and the highest insensitivity to media noise from slurries, low conductivity media, pulps, greasy sewage, paper mill liquors and similar.

The 4411e is a most versatile and advanced magmeter transmitter. It features a user friendly keypad for programming, a 10-year memory, batch control, RS232 interfacing, two x 4 – 20mA outputs and a scalable pulse frequency output.

There are two x 4 - 20mA inputs with 2 – wire capability. One may be used as a level input for use with ChannelMag open channel and other partially filled flowmeter.

4411e Feature	Benefit
High excitation current (to 5.5A base to peak) and high exciter frequency (40 Hz or 33 Hz for all size UniMag Sensors	Suitable for problem media (mining, slurries, pulps, low conductivity media); Signal to media noise ratio up to 50x higher than other magmeters; Suitable for media that coat the inside of pipes.
4 lines of 20 character alphanumeric, backlit LCD display with sealed, tactile feedback and vandal resistant keyboard	Clear rate display, gross and net totals in forward and reverse directions, and batch control; Field configurable and user-friendly keypad.
Noise Countervailence and Auto-Zero Circuits, with RF and VFD filtration	Signal virtually immune to common noise effects, including eddy current drift, radio frequency, variable frequency drives and similar.
Bidirectional flow measurement	Accurately eliminates back flow from net totals.
Reference coils to compensate for media magnetic fields and media temperature	Allows accurate flow measurement of slurries with magnetite and wide media temperature variation.
Fast time constant of 0.30 seconds	Accurate measurement of pulsating pump flow; Suitable for high speed batch fill times to 1 second; Stable, fast acting proportional control.
Comprehensive alarm relays and setpoints	Control of min/max and batch control; Alarm relays for reverse flow; Non-full pipe alarm actuated by external switch or by uncovered electrodes.
