Water & Wastewater Treatment Flow Solutions FAQ

Water & Wastewater Treatment Flow Solutions FAQ

Technical expert guide by RB Flowmeter on flow measurement for potable water, sludge, aeration, and biogas recovery.

Q1: When should I choose Magnetic over Ultrasonic meters in wastewater?
A: Generally, RB Flowmeter suggests magnetic meters (RBEF/RBHEF) for sludge and aeration lines where gas or solid content is high (>30%). Ultrasonic meters (RBXEF) are ideal for clean water or where non-intrusive clamp-on installation is required for existing pipes.
Q2: How do RB Flowmeter products handle remote locations without power?
A: Our RBEF/RBHEF series includes battery-powered standalone models. With a 1:400 turndown ratio and IP68 protection, they are perfect for remote well abstraction and water distribution networks where mains power is unavailable.
Q3: What makes the RBTMF ideal for biogas and aeration processes?
A: Unlike volumetric meters, the RBTMF Thermal Mass Flow Meter by RB Flowmeter measures mass flow directly without needing T&P compensation. It detects extremely low velocities (0.02 mps) and has no moving parts to clog in dirty landfill gas.
Q4: Can RB Flowmeter sensors measure flow in partially filled pipes?
A: Yes. We offer the RBEF-I Insertion Magnetic Flowmeter combined with a level transmitter for sludge, and the RBXEF Open-Channel Ultrasonic system for large distribution channels, ensuring accurate velocity-area calculations.
