In areas where the air is foggy, humid and dewy. Or some special-purpose industries, such as: the water in the gas purification circulating water suction well comes from the process cooling equipment in the chemical workshop (such as the primary cooling tower and the final cooling tower), and the water temperature is generally about 50 degrees, and then it is cooled to about 40 degrees through the air cooling tower and sent to the gas purification circulating water suction well. Because the humidity in the well is high, there is a lot of steam, and the temperature of water is higher than that of the probe of the liquid level gauge (especially the temperature difference between day and night inside and outside the well is large), so we can see the phenomenon that condensed water drops attach to the probe. The water droplets attached to the probe refract the ultrasonic waves emitted by the probe, which leads to the incorrect time difference between transmission and reception, and then the meter head control unit calculates the wrong liquid level.
Therefore, in order to solve the problem that water drops and condensation affect the liquid level measurement for users in the water industry, we introduce LT-200 ultrasonic liquid level meter of LETECH brand from Korea. In foggy and humid areas, rainy days or when condensation occurs due to temperature difference, when ultrasonic measurement is impossible, the sensor of this product adopts an arc shape to make the condensation quickly gather in the center of the surface to make it automatically drop, and 5 times of surface vibration per second can vaporize water molecules, thus solving various problems when condensation occurs.
