A blind area of ultrasonic thermometer used but not blindly follow

With the rapid development of China's economic construction, the application of the domestic industrial automation system to show a sharp rise. Industrial control systems technology has been used in more and more for Chinese companies. China should develop the instrument and meter industry and a large number of applications to the enterprise production, so as to achieve the effect of energy consumption, high output. In under the condition of normal temperature, atmospheric pressure, select ultrasonic thermometer to measure the liquid level is the best choice, has reliable operation, easy installation, use cycle is long, the characteristics of free maintenance, and has a relative price advantage. Ultrasonic thermometer due to launch ultrasonic pulse width has a certain amount of time, at the same time after launch the ultrasonic sensor and residual vibration during cannot detect the echo, so a short distance from probe surface down to detection, this distance is called the blind area. The highest level as measured into the blind area, detect instrument will not be able to correctly, can appear error. If necessary, can be heightened level meter installation. Adding plastic pipe, usable level calibration of the container should use a greater range of material level meter should use a greater range of material level meter or other measurement methods. Nature to return to work after charging or charging to switch to a greater range of material level meter.

the deviation level into the blind area of unstable power supply has a strong electromagnetic interference is blocking the object of sound waves in the material level meter made up metal flange on the probe surface or side. Contact with the metal higher security level meter or prevent the level is too high to improve the power supply to the material level meter after the earth or shielded changing plastic pipe installation position or to switch to plastic flanges using isolation rubber pad and metal magnetic flap UzL | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer
