This is where it all starts. Our meters are the brains of the whole operation. They are the link between collecting superior flow data, and conveying it to you in a convenient, reliable, and highly-functional manner. With options for stationary, portable, permanent or temporary usage, you have a choice for every scenario. From extremely rugged portable loggers, designed to handle all the abuse a manhole can dish out, to highly connectable stationary controllers, the Hach/Sigma/Marsh-McBirney line of flow meters have been perfected through decades of constant in-field use and innovation. But we aren’t stopping there. We continue to pioneer usage of new technologies, including wireless communications, to make field-worthy, state-of-the-art logging solutions for our industry.
