  • Page 17 Ultrasonic Level Meter Menu Simple Setting Operation Instructions ② Launch angle and false echo The ultrasonic wave speed is focused by the probe, and the emission of the pulse wave speed is like the speed of light of a flashlight. The farther away from the probe, the larger the diffusion area. Any object within the emission angle, such as: pipes, supports, welds, stiffeners, stirring propellers, and objects on the wall, will cause strong false echoes, especially objects closer to the probe within the emission angle.

  • Page 22 Ultrasonic Level Meter Menu Simple Setting Operation Instructions 4.2.5.2 Arched tank roof For arched tanks, the meter should not be installed in the center of the tank roof, but at or 2/3 of the tank roof radius (on the premise of meeting a certain distance from the tank wall). For the ultrasonic pulse, the arched roof is like a convex lens.
  • Page 23 Ultrasonic Level Meter Menu Simple Setting Operation Instructions 4.2.5.3 Open container For open containers, you can use a bracket for installation. Pay attention to the bearing capacity of the bracket to keep a certain distance between the sensor and the container wall.

  • Page 31 Ultrasonic Level Meter Menu Simple Setting Operation Instructions In the reservoir, generally, the installation height of the instrument should be determined according to the highest water level. The distance between the highest water level and the probe must be noted. There is a falling object at the bottom of the pool exposed when the water level is low.
  • Page 32 Ultrasonic Level Meter Menu Simple Setting Operation Instructions 4.3.3.2 Common installation errors ① Bubbles: If the bubbles on the surface of the medium are large and the bubble layer is thick, it will cause measurement errors and may not even receive the reflected ultrasonic waves. Take measures to prevent air bubbles, or install the sensor in the bypass pipe for measurement.
  • Page 33 Ultrasonic Level Meter Menu Simple Setting Operation Instructions ③ Install in a place with large temperature changes In locations with large temperature changes, such as: strong sunlight, it will cause measurement errors. This error will increase by 2-4% based on the original measurement accuracy. Please install a sun visor to solve it.
  • Page 34 Ultrasonic Level Meter Menu Simple Setting Operation Instructions 4.4 Electrical wiring diagram ★ Note: The length of the connecting cable between the probe and the host of the split-type ultrasonic level meter should be determined in advance. Do not go to the site and connect with other cables. Connecting the cable again in the field will affect the signal transmission quality and strength.
