MD-L101 low-power liquid level sensor
Low power water level gauge
Product details

The MD-L101 series low-power liquid level transmitter is based on the principle of liquid static pressure to measure liquid level or water depth. It uses a diffusion silicon isolation membrane sensor as the sensitive element, and then converts static pressure into standard electrical signal output through precise temperature compensation technology and water sealing technology.

The MD-L101 series low-power liquid level transmitter adopts a digital conditioning circuit, which has the advantages of low power consumption, fast response speed, and short power on stability time. Low power design can meet the application scenarios powered by batteries, especially for applications in smart cities, smart firefighting, smart water management, and other fields.
