ESMUL21 10m range non-contact ultrasonic level transmitter for 24vdc/220vac

The working principle of the ultrasonic level meter is that the ultrasonic transducer (probe) emits high-frequency pulse sound waves, which are reflected back when they encounter the surface of the measured material. The reflected echo is received by the transducer and converted into an electrical signal. The propagation time of the sound wave is proportional to the distance from the sounding of the wave to the surface of the object. According to the formula S = C × T / 2 (where S is the sound wave transmission distance, C is the speed of sound, and T is the sound propagation time), the distance from the probe to the liquid level can be calculated.

1. Circuit Design from the power supply section on the selection of high-quality power from the module, component selection of imported high reliable device can replace the same type of imported instruments.
2. Patented sonic intelligence software for intelligent echo analysis, debugging, and without any other special steps, this technique has a dynamic thinking, dynamic analysis capabilities.
3. My company has patented sonic technology intelligence, greatly improving the accuracy of the instrument, level accuracy of ± 0.25%, resistant to all kinds of interference waves.
4. The instrument is a non-contact instrument, not in direct contact with the liquid, and therefore low failure rate. Instrumentation offers a variety of installation, the user can through this manual instrument calibration.
5.All input and output lines of the instrument have lightning protection, short ci.
