Ultrasonic level meters TUSLevel-TL-X

Introduction

Ultrasonic level meter is based on the Time-of-Flight principle. A sensor emits ultrasonic pulses, the surface of the media reflects the signal and the sensor detects it again. The Time-of-Flight of the reflected ultrasonic signal is directly proportional to the distance traveled. With the known tank geometry, the level can be calculated.

Advantages

Price-favorable solution for simple applications.
Maintenance-free operation through non-contact measuring principle.
Reliable measurement independent of product features.

Application
Ultrasonic level meter for continuous level measurement of liquids or bulk solids. Typical applications are the measurement of liquids in storage tanks or open basins. The sensor is also suitable for the detection of bulk solids in small vessels or open containers. The non-contact measuring principle is independent of product features and allows a setup without medium.

Introduction

76-81GHz frequency modulation wave FMCW radar product (also called millimeter wave radar), it uses a millimeter wave band with high frequency, it can detect smaller targets and achieve more precise positioning than microwave radar with higher resolution and stronger confidentiality. Therefore, it has important applications in long-distance target detection, strong smoke and dust environment, long-distance imaging, multi-spectral imaging, etc.

Advantages

Based on self-developed millimeter-wave radio frequency chip to achieve a more compact radio frequency architecture.
Higher signal-to-noise ratio, almost unaffected by level fluctuations.
The measurement accuracy is millimeter-level accuracy (1mm), which can be used for metrology-level measurement.
The measurement blind area is small (3cm), and the effect of measuring the liquid level of small storage tanks is better.
The beam angle can reach 3°, and the energy is more focused, effectively avoiding false echo interference.
High frequency signal, can effectively measure the level of medium with low dielectric constant (ε≥1.5).
Strong anti-interference, almost unaffected by dust, steam, temperature and pressure changes.
The antenna adopts PTFE lens, which is effective anti-corrosion and anti-hanging material.
Support remote debugging and remote upgrade, reduce waiting time and improve work efficiency.
It supports mobile phone Bluetooth debugging, which is convenient for maintenance work of on-site personnel.
