Sigma was started in 1980 with the goal to become the leader in the design
and manufacture of innovative flow monitoring instruments. Since then, Sigma
has reached that goal, and added communication products and data acquisition
software to its list of achievements.

A flow management program designed by American Sigma will detect
infiltration and inflow, limit overflows that can cause health risks and
environmental damage, and save your facility considerable time and expense.
American Sigma flow meters are designed for accuracy and efficiency, to create
the most effective use of maintenance budgets and provide a defendable billing
system for sewer use and treatment.
