Resolve the cause of fluctuations in the flow meter readings during inverter pump operation! We will also introduce some key points!
When the old-style pump and the inverter pump are operated simultaneously, the flow rate displayed on the central monitoring room's screen for the old-style pump fluctuates and shows abnormal values. The water purification plant management company, Company D, was troubled, suspecting that there might be some issue with the inverter pump. The cause was that high-frequency noise generated by the inverter pump was affecting the flow meter's data. Our company installed a noise-cutting transformer on the power supply line of the inverter pump and applied electromagnetic shielding to each cable to prevent high-frequency noise from propagating into the space. [Case Summary] ■ Problem: The flow rate of the old-style pump fluctuates and shows abnormal values. ■ Product Introduced: Noise-cutting transformer "Noise Cut Transformer" ■ Effect: Prevents high-frequency noise from leaking into the power supply line. *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Key Points】 - Inverters are prone to becoming sources of high-frequency noise, so caution is necessary. - Sensors tend to be more susceptible to noise as their sensitivity increases, so it is recommended to implement effective noise countermeasures. - High-frequency noise transmitted through power lines and high-frequency noise transmitted through space require different countermeasures, so it is essential to take appropriate actions. *For more details, please refer to the PDF document or feel free to contact us.*
