flow meters

 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...
