English
The integrated ultrasonic liquid level meter is a digital liquid level meter controlled by microprocessor. In the measurement, the pulse ultrasonic wave is sent out by the sensor, and the sound wave is received by the same sensor after reflected by the liquid surface and converted into electrical signal. The ultrasonic liquid level meter has the functions of automatic power adjustment, temperature compensation and anti-interference. environment
The integrated ultrasonic liquid level meter can adopt two-wire system, three wire system or four wire system technology. The power supply circuit and signal output circuit are independent. When using DC 24 V power supply, a 3-core cable can be used. The negative end of power supply and the negative end of signal output share one core; When AC 220 V power supply is adopted, or when DC 24 V power supply is adopted, the power supply circuit and signal output circuit shall be completely isolated, a 4-core cable shall be used. DC or AC power supply, with 4 ~ 20mADC, high and low switch output.
Application of integrated ultrasonic liquid level meter:
1. Measure flow, liquid level, low gauge pressure, vacuum and specific gravity
2. The two-wire Zui has a large range up to 30m
3. Four wire Zui with a large range up to 40m
4. Zui small resolution 1 mm
5. Large LCD / LED display
6. Intelligent signal processing technology
7. Equipped with high and low position double relay (four wire system only)
8. All plastic anti-corrosion shell (protection grade lp67)
9. Transducer structure (when installing flange of small range level meter, there is no requirement for the length of flange nozzle)
10. Simple key setting parameters (no need to wait for the container to empty or fill, no need for additional remote control)
11. Flexible installation method (thread / flange, fixing hole / bracket)
Thread size: G2 "(generally applicable to three wire and four wire wiring)
M66 * 3 (generally applicable to two-wire wiring)
12. AC or DC power supply mode is optional (four wire system only)
