Safety Warnings When installing, operating, and maintaining McCrometer equipment where hazards may be present, you must protect yourself by wearing Personal Protective Equipment (PPE) and be trained to enter confined spaces. Examples of confined spaces are manholes, pumping stations, pipelines, pits, septic tanks, sewage digesters, vaults, degreasers, storage tanks, boilers, and furnaces. -
Page 4: Introduction
2 .0 PRINCIPLE OF OPERATION The Mc Mag3000 uses Faraday's Law of Electromagnetic Induction to measure water velocity. Faraday's Law states that a conductor, moving through a magnetic field, produces a voltage. Charge carriers in the fluid produce a voltage when passing through a magnetic field. The magnitude of the voltage is directly proportional to the velocity at which the fluid moves through the magnetic field. -

3 .0 INSTALLATION 3 .1 Packaging Note When you unpack the Mc Mag3000, you will find a red plastic cap over the front push button. This can be discarded with the rest of the packing materials. 3 .2 General Installation Considerations Proper meter installation is the first step to ensure excellent meter performance. -
Page 6: Straight Pipe Requirements
Installation 3 .4 Straight Pipe Requirements Flow meters are velocity sensing devices and are vulnerable to certain upstream disturbances. Because of this, meters need certain lengths of straight pipe before and after the meter. These distances relate to the diameter of the pipe used. -

Installations Replacing Existing Saddle Meters The Mc Mag 3000 can be used to replace existing McCrometer saddle meters. The Mc Mag 3000 can be installed with Water Specialties bolt-on saddle meter cutout templates for 6” meters and 8”-20” meters, as well as with McPropeller bolt-on saddle meter cutout templates for 12”-16”... -
Page 8: Grounding
3 .6 Grounding The Mc Mag3000 is fitted with a grounding lug on the saddle for proper grounding. For typical installations the lug can be connected to an earth ground and/or the metal pipe in which it is installed. For electrically noisy installations connect the grounding lug to a dedicated, low impedance earth ground. Low impedance is 10 Ohms or less. -
Page 9: Converter Boot
Installation 3 .7 Converter Boot The Mc Mag 3000 comes with a boot to help protect the meter. NOTE: It is HIGHLY recommended that the boot be utilized at all times when the meter is not being read. The boot adds protection to the meter and insures proper closure of the lid, insuring the maximum battery life. -
Page 10: Operation
The Mc Mag 3000 comes pre-configured from the Factory based on the installation parameters provided to McCrometer at the time of order. Other than activating the display, there is nothing required of the user for the basic operation of the flow meter. - Page 11 Operation 4 .3 .2 Second Display Screen The second screen display shows the battery life remaining for both battery packs and the flow totalizer. In the sample below, both battery packs are at 99% and total flow is 500 kilogallons. Battery life remaining Totalizer Figure 9 .
