While radar level meters and ultrasonic level meters are right or wrong touch level meters, ultrasonic uses sound waves and radar uses electromagnetic waves, which is a big difference.
Ultrasonic level meter and radar level meter are widely used in petroleum, chemical, pharmaceutical, environmental protection, water outside the field, many users do not know how to choose. I will tell you the five differences between ultrasonic level meter and radar level meter: the principle is different. Ultrasonic level meter using sound waves, radar level meter using electromagnetic waves. Different media temperature and pressure: ultrasonic level meter is only used for atmospheric pressure vessels, the probe temperature does not exceed 80 ℃, the speed of sound by the temperature and pressure is greatly affected.
Radar level meter is an electromagnetic wave, not affected by vacuum, applicable to medium temperature and pressure. Different categories of radar level meters: horn, rod, cable, can be used in different measuring conditions, radar is an electromagnetic wave, not affected by vacuum, ultrasonic can not be used in vacuum, too high vapor content, liquid level with foam and other conditions. Price difference: the price of radar level meter is higher than ultrasonic level meter. Different precision: the precision of radar level meter is higher than ultrasonic level meter.
However, whether it is radar level meter or ultrasonic level meter, when the device is installed on the tank, do not install it in the inlet, do not install it near the ladder, 300 to 500mm interval from the tank wall to avoid echo interference. In the case of agitation and level fluctuations, should also choose the appropriate device method.
