flowers, set many advantages of ultrasonic thermometer it and when to use what trouble?

ultrasonic thermometer is widely used in water and wastewater treatment: when the use of the instrument conditions, environment humidity, ventilation, dust and more transmission distance is small, can choose separation close type. When measured corrosive liquid, can choose the body near the anticorrosive thermometer, also can use an anti-corrosion type ultrasonic thermometer, but integrative machine installation location of the storage tank sealing requirement is higher. When filtering gate the width of the pool area is small. Especially when the pool depth is more than 10 m ( Depending on the area of the pool size) Suggest the lead pressure thermometer using ultrasonic liquid level difference time should pay attention to.

ultrasonic thermometer not only have many virtues, on the contrary shortcomings also exist at the same time, the ultrasonic thermometer can measurement of body temperature range from ultrasonic can in aluminium and coupling between transducer and pipeline material heat resistance level of restrictions, be sound transmission flow velocity and high temperature of raw data is not complete. In addition, ultrasonic thermometer measuring circuit complex than normal. For general industrial measurement of liquid flow velocity is often a few meters per second, and propagation velocity of sound waves in a fluid is about 1500 m/s, by flow velocity ( Traffic) If requirement for the accuracy of measuring the velocity of 1%, the measurement accuracy of the sound velocity for 10 - 5 ~ 10 - 6 orders of magnitude, so there must be a perfect measuring circuit to achieve.
