What precautions are needed for ultrasonic flowmeter winter installation and low temperature effects?

Winter ultrasonic flowmeter installation requires special attention to low temperature effects on equipment performance and installation procedures. When ambient temperatures drop below -10℃, electronic component characteristics change, affecting measurement accuracy and equipment lifespan.

• Pipe preheating: For clamp-on ultrasonic flowmeters, ensure pipe surface temperature >0℃ before installation to prevent poor sensor-pipe contact
• Coupling agent selection: Use freeze-resistant coupling compounds maintaining acoustic conductivity at -20℃ and below
• Cable protection: Employ cold-resistant signal cables with outer jackets withstanding -40℃ without cracking
• Equipment insulation: Install converters in insulated enclosures, add heaters when necessary to maintain 5-40℃ operating temperature
• RTU systems: EC32/EC60 RTU series in extreme cold regions require battery insulation measures for proper lithium battery operation

Installation personnel should wear appropriate cold weather gear and use insulated tool cases, preventing prolonged equipment exposure to harsh winter conditions.
