Knowledge Base

Q

The selection of float size for float type liquid level sensors should be based on the density of the measured liquid and the required buoyancy: the smaller the liquid density, the larger the required float volume (buoyancy=density x volume x gravitational acceleration) to ensure that the float can float on the liquid surface and drive subsequent mechanism actions; If the viscosity of the liquid is high, the float should be appropriately increased to avoid being stuck by the liquid and unable to float

Q

This article provides a detailed introduction to the working principle of float type liquid level sensors, as well as their applications as liquid level displacement sensors and floating liquid level displacement sensors. It explores the application and advantages of such sensors in various practical scenarios.
