What are the requirements for ultrasonic flowmeter coupling agent usage? How often should it be replaced?

Ultrasonic flowmeter coupling agent requires -40℃ to +200℃, 0.1-0.5mm thickness, 3-6 months replacement

Ultrasonic flowmeter coupling agent is a critical medium ensuring good acoustic coupling between sensors and pipes. Proper use of coupling agent directly affects measurement accuracy and signal stability.

Coupling agent usage requirements:

  • Temperature range: -40℃ to +200℃, select appropriate grade coupling agent
  • Application thickness: 0.1-0.5mm, too thick or thin affects signal transmission
  • Coverage area: Complete coverage of sensor contact surface, no air bubbles
  • Cleanliness requirements: Pipe surface must be polished smooth, remove rust and oil
Replacement cycle recommendations:
  • Normal temperature environment: Check every 3-6 months
  • High temperature environment: Check and replace every 1-3 months
  • Outdoor installation: Every 2-4 months depending on weather conditions
Ecolor Technology provides specialized high-temperature coupling agent and waterproof coupling agent to meet various harsh operating conditions.
