IDWR Approved Electromagnetic Flow Meter

Dura Mag flow meters with DC power underwent rigorous testing by the Utah Water Research Laboratory at Utah State University using NIST* traceable instrumentation and performed at or above the IDWR standards. The Dura Mag is approved for use in Idaho in the installation of flow meters by water users that divert water in regulated areas from both ground and surface water sources.

Irrigation Flow Meter Designed for Ease of Installation

McCrometer has been innovating flow solutions for irrigators since 1955. Their all new Dura Mag provides precise, reliable flow data for water management. Plus the intelligent converter features a spring-loaded canopy lid to protect it from extreme weather and harsh sunlight, and the push-button display and onboard data logger records flow rate and totalized flow. The empty pipe alarm will help growers improve irrigation efficiencies.

Proven Electromagnetic Technology

Dura Mag builds on McCrometer’s proven electromagnetic sensing technology, which combines intelligent sensor and converter design with advanced materials for accurate measurement, long-life and low maintenance. The meter’s fusion-bonded epoxy coating requires no liner, eliminating the risk of liner separation and water intrusion through the meter body.
