Hach Flo-Dar

The Hach Flo-Dar measures open channel flow without ever touching the water. A radar velocity sensor and ultrasonic level sensor mount above the flow, so there's nothing in the pipe to foul, snag ragging or wash away — ideal for harsh wastewater and high-velocity sites.

Key features

• Non-contact radar velocity measurement
• Ultrasonic level measurement from above the flow
• Optional surcharge velocity sensor for submerged conditions
• Minimal maintenance — no sensor in the flow stream
• Pairs with Hach FL900 and FL1500 flow loggers

Common applications

• Sanitary sewer influent and collection systems
• Combined sewer overflow (CSO) monitoring
• Stormwater outfalls
• Industrial discharge and pretreatment
