We have about 100 Sigma units that we own ourselves for temporary flow monitoring for our clients and there are around 200 permanent Sigma meters that we operate for various clients.  We don’t have any problems with the meters so when it comes time to recommend a meter type for a proposal, that’s what we choose!” ~Frazier Engineering

“We’ve reduced a tremendous amount of I/I (with Sigma meters). In the areas that we have been working, the payback in rehabilitation costs is about eight years. Also, a $6 million treatment plant expansion will not be necessary because flows have been reduced.” ~Naperville, Illinois

“The 950 is a good meter. Of the meters I work with 90% have bubblers, (1) has ultrasonic, and (2) use the submerged pressure sensor. The meters are easy to configure, easy to set up and they are reliable.” ~Stephens Instrument Service
