Precision You Can Rely On: Rheotherm® Flow Instruments for the Water & Wastewater Industry

In today’s water and wastewater industry, reliable flow measurement is not just about numbers—it’s about meeting compliance, protecting infrastructure, and optimizing operations. Whether you’re fine-tuning chemical dosing, monitoring digester gas, or automating stormwater treatment, Rheotherm® flow meters and flow controllers deliver performance you can count on, even in the most demanding environments.

Smart Flow Solutions for Smarter Water Systems

From large-scale treatment facilities to remote, unmanned sites, Rheotherm flow instruments are built for the challenges of modern water management. With zero moving parts and high resistance to corrosion, they offer long-term accuracy with minimal maintenance—saving time, money, and resources. Rheotherm meters are constructed out of a variety of wetted materials for compatibility with highly corrosive acids or sodium hypochlorite.

The Rheotherm line specializes in low flow measurement and control, making them the perfect instruments to automate the dispensing of water treatment chemicals.

The automatic metering, or pacing, of coagulants, fluoridation agents, stabilization agents, or other additives can be tied directly to the real-time flow rate of the incoming water, turbidity, or zeta potential measurements. This allows the unit cost of treatment to be closely controlled, improving efficiency, reliability, and savings.
