Ultrasonic level meter （Integrative）

 
Ultrasonic Level Meter derived from a variety of excellent foreign level meters and achieve digital, industrialization, humanized design with sound level measurement functions, control functions, data transmission functions and Man-machine interaction. The set which collects send -and -receive ultrasonic sensors, servo circuit, temperature compensation sensor and that compensates circuit modules, displays, control signals and serial data output or analog output module is one of the explosion-proof level measuring instruments. it has a comprehensive function , stable performance, reliable condition. And it is widely used in explosion-proof and meter fields, such as liquid level measurement or other control occasions.
 
Ultrasonic Level Instrument because of a non-contact detection, is healthier and more resistant to moisture, dust, high temperature, corrosive gas, such as harsh environment (specifically the whole seal type of sensors).With less maintenance, non-pollution, high reliability, long Life expectancy and other advantages, it is widely used in petroleum, paper, mining, power plants, chemical industry, water treatment plants, waste water purification, pharmaceutical industry, agricultural pumping, environmental monitoring, sewage treatment, and food industry(wine industry, beverage industry , additives, edible oil, dairy products, etc) and other industries and explosion-proof environment level, material level measurements.
 
Main Functions
 
It can be carried out the accuracy of calibration in different environments, start-stop-point range, the output type of analog mode; window level figure can be locked by keyboard settings.
With a wide range of temperature compensation and original ERD interfere intelligent identification system, it enables measurement stable and accuracy high.
It has the value / difference measurement mode selection.
Users can choose to buy a host or PC software network which can manage 2 ~ 128 extensions.
It can be directly measured weight of the tank liquid, level value (weight value) may be measured by LED or LCD display and teletransmit data.
It can show rich information, including the level, weight, temperature, output current / voltage, limit switch, level address, etc. The installation and maintenance are very easy.
Thanks to full-scale spill prompts, and full-scale start and end arbitrary figure of translation functions, it is convenient for users and dealers.
Display can be set with the stability function, the display resolution d = 1cm, d = 1mm .The users can select freely (computation precision of the same).
 
With "echo Intelligent Recognition" and "slope" digital filter function, it applied for different conditions of acoustic magnetic interference.
 
With 4mA, 20mA digital tuning function, installation and commissioning and maintenance are very precise and convenient on the site.
1 ~ 15degree with a transmitter power selection; with 10 second / second ~ 100 times / second cycle Detect Settings feature in order to adapt to speed measurement of moving targets to capture ... ... and many other advanced features.
