WKL-ULT-C ultrasonic water level sensor is a level measurement instrument which non-contact, highly reliable, cost-effective, easy to install, and maintain. High-quality ultrasonic liquid level sensor comes standard with temperature compensation, digital filtering, and echo recognition functions, effectively shielding false echoes. Large-screen LCD, liquid level/current/temperature display on the same screen.

how does an ultraosnic level sensor workPrinciple

Install height G: ( probe to the height of the tank bottom)
Liquid level H: ( level or material level height)
Air distance L: (probe to test surface area)
Blanking distance C: (a small area below the sensor)
Instrument range d: (generally from zero to the highest plane, only linearly corresponding to output P)

Formula：
1、Ranging：L=S*T/2；  S=331.45+0.61*n℃
2、Level：H=G-L
3、Output： P=H/d*16+4 or P=L/d*16+4 （Note: P output current in mA）

  • Automatic temperature compensation;
  • Wide versatility and low price;
  • With value-added/difference ranging options, you can measure both distance and level
