Ultrasonic level meter

Intraduction
            Ultrasonic level meter is microprocessor controlled digital level meter. Ultrasonic pulses generated by the sensor (transducer) emitted in the measurement, the surface acoustic wave after reflection by the liquid receiving same sensor or an ultrasonic receiver, by a piezoelectric crystal or a magnetostrictive device into an electrical signal by transmitting and receiving sound waves to calculate the time between the sensor surface to the distance measured liquid.Features


Feature
1. Has a strong anti-interference. Upper and lower limits can be set to adjust the output node and online, and with on-site display, select the analog, digital and RS485 output for easy interface  with related facilities.
2.Case is quite compact and rugged, with excellent chemical resistance, for inorganic  compounds,regardless of acid, alkali, salt solutions, in addition to strong oxidizing materials,almost all of its non-destructive effect on almost all solvents at room temperature are insoluble, general dioxane, hydrocarbons, alcohols, phenols, aldehydes, ketones and other media can be used.
3. Light weight, no scaling, do not pollute the media
4. Non-toxic. Can be used in medicine, food industry equipment installation, maintenance is very easy
