About this document
Impact of PCV Noise on ALTOSONIC V12 by jittshong8072 is a document available to read on EtoBox.
This technical document discusses the effects of pressure control valve noise on ultrasonic flowmeters like the ALTOSONIC V12. It explains that while humans can only hear sounds between 20 Hz to 20 kHz, ultrasonic flowmeters operate at much higher frequencies, typically 100-350 kHz for gas. Noise from pressure control valves within this frequency range can interfere with ultrasonic signals. The document recommends installing pressure control valves downstream of the flowmeter and includes noise reduction le
