ABOUT

Aqua-Magnetic's core team combines over 100 years of experience developing electromagnetic sensing technology for water and wastewater applications.  Maintaining our core competency, Aqua has developed state of the  art sensors with smart phone compatibility. 

​

Each sensor is calibrated in our 150 foot long towing facility, ensuring each product delivered measures to the highest standards. 

The electromagnetic velocity meters manufactured and sold by Aqua-Magnetics  have their beginning as long as 50 years ago.
When Larry Marsh and Dick McBirney started Marsh-McBirney, inc. in 1971, the measurement of municipal and industrial water and wastewater flow was changed significantly.  Larry Marsh invented most of the electromagnetic flow meters that are sold by the major manufacturers selling in this industry today.  Marsh-McBirney was sold to Hach and McCrometer in 2005.  Marsh continued to invent and patent many additional  electromagnetic flow meters. These new flow meters are now being manufactured or developed for future use by AquaMag’s customers.
