1.Profiles:
Ultrasonic Level Sensor with Indicator is a non-contact, high reliability, cost-effective, easy installation and maintenance of level measurement instruments. It does not have much contact with the media will be able to meet the requirements of level measurement, which was developed after years of efforts the company has a complete new generation of proprietary ultrasonic level meter.
2. Measuring principle:
Ultrasonic Level Sensor with Indicator emits ultrasonic pulses transmitted through the transmission medium to the measured body surface, the reflection and then return through the medium of sound propagation to the receiver transducer to measure the ultrasonic pulse from transmitter to receiver propagation in the medium of sound propagation time. Sound transmission medium according to the speed of sound, can be called from the transducer distance to the object plane to determine the material level.
3. Features:
1) Exclusive use of the physical and sealed probe.
2) Unique probe design, the pressure to adapt to the environment 16 kg.
3) Advanced echo tracking algorithm
4) A variety of compensation mode.
5) Dot-matrix LCD, full English menu
6) Flexible measurement mode: Two Level and distance measurement mode, and it's flexible to set the reference position, so that display is more intuitive.
7) Programmable relay output
