1.0 Description

The OMEGAMAG measures the fl ow rate in a full pipe by monitoring the voltage produced when the (conductive) fl uid moves through a
magnetic fi eld.
Output options include a traditional frequency signal and a 4-20 mA output.
The OMEGAMAG is available in two sizes that will accommodate pipes from ½ inch through 8 inch diameters.
Select from three different material combinations to match the magmeter to the application requirements.

3.1 Location of Fitting

The magmeter can only measure fl ow if the pipe is full.
If the piping system has entrained air pockets, take steps to locate the sensor so the air pockets will not contact the electrodes.

These confi gurations guarantee that the pipe is always
fi lled. The sensor cannot be exposed to air bubbles.

Avoid these situations unless you are certain that the
sensor will not be exposed to air bubbles.

In a gravity-fl ow system, the tank must be designed so the level
does not drop below the outlet.

This causes the pipe to draw air in from the tank.
If air bubbles pass across the Magmeter electrodes, the output
will become erratic.

If the pipe is not full, or the electrodes are not immersed, the
fl ow display will show zero and all output functions will behave
accordingly.

If the magmeter electrodes are exposed to fl ow transitions and air
bubbles, the measurement may be incorrect until the conditions
are stabilized.

4.0 Overview of Display Magmeter

Display Magmeters use a dual-sided electronics module and dual conduit ports. Unused ports must be sealed to prevent corrosion and
moisture from entering the circuitry.

1. The lower set of conduit ports provide access to the wiring terminals for:

• Loop Power

• Flow Output Signal, whether it is a current loop, a frequency or the Mirror Relay 1 output.

2. The upper set of conduit ports provide access to the wiring terminals for:

• Relay output wiring

• Auxiliary power for relay coils and display backlight

3. The sensor is marked with a directional arrow to indicate the direction identifi ed as forward fl ow.
An adhesive decal is also provided that can be affi xed to the pipe to indicate the direction of forward fl ow.
Flow in the opposite direction from the arrow will be identifi ed as reverse fl ow on the display by a "-" symbol.

4. The terminals in the magmeter are designed to accomodate 14 to 22 AWG conductors.

5. The display includes two LEDs that light when Relay 1 or Relay 2 are activated.

• All three relays can be monitored by scrolling to the Relay Status display located in the View

English >

menu.

• If the Language option has not been made, new magmeters will always open with the Select Language display.

6. The part number, serial number and output type are identifi ed on the electronics module.

• The 4-20 mA output can be spanned to any range, from -10
m/s to +10 m/s.

• AUX PWR must be connected to power the display
backlighting and to power to the relay coils if included.

5.5 Wiring Relays

Relay 1, Relay 2 Type: Mechanical SPDT
Rating: 5A @ 30 VDC max., 5 A @ 250 VAC max

Relays 1 and 2 are dry contact relays rated for 5 A maximum current.
Relays 1 and 2 are best suited for switching high voltage loads, such as AC
powered pumps and valves.

When used to switch inductive loads, dry contact relays may be damaged by
arcing. Omega recommends the installation of a fi lter device to prevent such
damage.
