Level Meter


The ultrasonic pulse is sent by sensor in the measurement,the sound wave reflected by the liquid’s surface is received by the same sensor, through the piezoelectric crystal converted into electrical signals, the time between the transmission and reception of the sound wave can be calculated the distance from the sensor to the surface of the liquid to be measured.



Measure principle:

Ultrasonic liquid level meter is digital level meter controlled by microprocessor.

The ultrasonic pulse is sent by sensor in the measurement,the sound wave reflected by the liquid’s surface is received by the same sensor, through the piezoelectric crystal converted into electrical signals, the time between the transmission and reception of the sound wave can be calculated the distance from the sensor to the surface of the liquid to be measured.

Due to adopting the non-contact measurement, the measured medium is almost unlimited,and it can be widely used for measure the various liquid and solid materials.

 

Feature

1. Small size, easy to install and place, convenient maintenance.

2. Strong anti-interference ability.

3. The instrument has the advantages of safety, cleanness, high precision, long service life, stability and reliable,convenient installation and maintain, it’s suitable for acid, alkali, salt, anti-corrosion, high temperature and other filed.

4.The instrument can be connected to the display meter or various DCS systems through 4~20mA or RS485(Modbus protocol and other customized protocols), and it can provide the real-time liquid level date for industrial automatic operation.

5.In the circuit design, the high quality power modules is selected from the power part, and import high stable and reliable components are selected, it can be completely replace the same type of import instrument.

6.The unique sound wave smart technology software can carry out intelligent echo analysis without any debugging and other steps,this technology has the function of dynamic thinking and dynamic analysis.

7.The instrument is an non-contact meter, the failure rate is low because no directly touch the fluid.the instrument can provide many installations methods,the user can calibrate the instrument through this manual.

8.All input and output line of the instrument have lightning protection and short circuit prevention functios.
