1. Product Overview ML-100 intelligent external ultrasonic level meter, is a new technology developed by our company, new products, level measurement using a sensor attached to the outside, and the measured liquid non-contact measurement is the liquid A major innovation in the history of level measurement. ML-100 intelligent external ultrasonic level meter, continuous measurement of liquid level in the tank, but the tank is not opening for installation without shutdown, especially for the replacement of old products. ML-100 intelligent external ultrasonic level meter is particularly suitable for a variety of toxic substances ﹑ ﹑ acid alkali and various level of pure liquid sealed container for precise measurement instruments using explosion-proof design, can require proof of occasions applications. 2. Works Mike Lake Automation Instrumentation Co., Ltd. ML-100 external ultrasonic level meter with a radar echo ranging principle, overcome the impact of the tank wall of ultrasonic signals, using advanced digital signal processing technology, can truly achieve non-contact, high-precision measurement of the level tank. Level gauge can output 4 ~ 20mA standard signal or via RS-485 interface will measure the results of the output bit-oriented computer (or the second table) satisfy the system of automatic control. 3. Product Features ● Non-contact measurement: industrial instrumentation in the best way ● High precision measurements, responsive ● wide applicability: available for highly toxic, corrosive, high-pressure industrial complex conditions, and various liquid media explosive gas environment measurement ● Easy installation, simple operation ● Installation without shutdown, unclear cans, no flare ● ● instrument does not require periodic calibration instrumentation reliable, stable performance ● no need to use square meter repair, maintenance-free long life ● ● intelligent, electronic instruments and strong anti-interference ability 4. ● Features ● Non-contact level measurement function ultrasonic sensor (probe) external, without opening the container to be measured. ● Automatic calibration gauge has a self-calibration function, to overcome the traditional level after taking into account long-term use, the accuracy decreases. ● IR infrared convenient online debugging function debugging capabilities, especially for openings in dangerous situations should not be debugged occasions; at the same time reducing the debugging difficult. ● Self-diagnostic function gauge the state have their own diagnostic work function, but also has a hardware diagnostic capabilities; thus increasing the reliability and stability of the level gauge. ● When a key recovery function gauge not working, you can debugger, a key to return to the normal state. ● Local display and remote function gauge both convenient display level value in the field, but also through the signal line to its remote control room. 5.
