  Q1: What pipe materials are compatible with the RBCS Clamp-On Ultrasonic Flow Sensor? Clamp-On Ultrasonic Flow Meter ipe Material FAQ | RBCS Series | R&B Instrument A: The RBCS Series is optimized for high-purity plastic tubing commonly used in cleanrooms—including PFA , PTFE , PVDF , and Nylon —as well as homogeneous metal pipes like 316L stainless steel and copper . It covers pipe outer diameters from 1/4'' ( 6.35mm ) up to 60.3mm . Q2: What are the main physical limitations of non-contact clamp-on ultrasonic measurement ? A: Clamp-on measurement can be limited by three main factors: Pipe Wall Condition: Multi-layer lined pipes with air gaps, porous cast iron, or heavily corroded walls scatter acoustic signals. Fluid Composition: High concentrations of entrained air bubbles or dense suspended micro-particles absorb ultrasonic waves. Pipe Fill: The pipeline must remain fully filled ( 100% ) without air pockets or half-empty gravity flow. Q3: What alternative R...

 In industries ranging from municipal wastewater treatment to chemical dosing, electromagnetic flowmeters (magmeters) are preferred for their obstruction-free, high-accuracy measurements. However, one of the most common diagnostic errors engineers encounter is " Excitation Failure ." When the transmitter loses its connection or signal from the magnetic field coils inside the sensor, the meter can no longer calculate fluid velocity. This guide by RB Flowmeter explores why this happens and how to prevent it. Troubleshooting Magmeter Excitation Failure What Causes Excitation Failure? 1. Moisture Ingress : This is the leading culprit in water distribution networks and wastewater plants. If the junction box or sensor body is not sealed correctly, humidity or water enters, shorting out the excitation coils. 2. Cable Degradation or Loose Wiring : Constant vibration in industrial plants can loosen terminal connections. Additionally, using non-shielded cables near high-voltage lines...
