McMag 3000

McCrometer’s award-winning Mc Mag 3000™ provides growers and irrigators with a new alternative for flow measurement. With a 5-year meter warranty, a 5-year battery life, and saddle mount design, the Mc Mag 3000 delivers the dependability and ease-ofinstallation McCrometer has provided to the agricultural market for nearly 60 years. The electromagnetic sensor offers accuracy as good as ±1% while being designed to naturally shed debris.

The meter is available to fit a common range of agricultural line sizes, from 4” to 12” diameter pipe.

The innovative design of the Mc Mag 3000 saddle mount meter features a multi-point angled sensor that sheds debris, making it ideal for use in surface water, livestock waste lagoons, and other dirty water applications.

Using electromagnetic technology to measure the water flow, the Mc Mag 3000’s precision sensor corrects for shifting velocity in the pipe by constantly obtaining the mean velocity from its multiple electrodes. The result is a highly accurate (as low as +/- 1%) flow meter.

The meter combines an innovative saddle, precision sensor, and a battery powered integrated electronic converter package with data logging capability to provide accurate flow measurement for full-pipe flow monitoring applications.

The integrated electronic converter is secured with tamper resistant screws to protect against unauthorized access. The meter offers flow rate and total water used and a 5-year warranty. The Mc Mag 3000 features three 3.6V lithium-thionyl chloride (LiSOCI2) D size batteries, with one serving as back-up power. The main power batteries are easily replaced in the field. Pulse and 4-20mA output are available for remote meter reading or SCADA. The Mc Mag 3000 is McCrometer CONNECT wireless system compatible, which allows users to access flow data by simply logging on to the Internet. This eliminates costly manual meter reading.
