Hachflow
About
Hach Flow (now operating under McCrometer, a Veralto Water Quality sister company) specializes in open-channel and closed-pipe flow measurement instrumentation for municipal and industrial water and wastewater applications. The FL900 Series Flow Logger serves as the platform for remote sewer flow monitoring, while the FL1500 multi-channel controller handles up to four independent flow sensors with integrated rain gauge, pH, and sampler inputs. The flagship FLO-DAR AV Sensor uses digital Doppler radar velocity combined with ultrasonic level sensing for non-contact flow measurement in harsh wastewater environments, handling velocities up to 20 ft/s, high solids, and shallow flows. The Submerged AV Sensor provides 1 MHz acoustic Doppler measurement with improved fouling resistance, available in oil-filled and non-oil-filled configurations. Portable field instruments include the FH950 handheld velocity and depth meter paired with the EM950 portable sensor for river profiling and flow data verification. For closed-pipe applications, the FPI Mag 3000 insertion electromagnetic flow meter and Water Specialties Propeller Meter serve agricultural, municipal, and industrial installations. The Redundant-Level Flow Monitoring System combines a submerged AV sensor with a US9003 ultrasonic sensor to eliminate data gaps. Hach Flow also offers Data Delivery Services (DDS), a turnkey monthly service providing equipment, installation, and data management.
