Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • In the actual procurement process of float level switches, it is recommended to prioritize confirming key technical parameters such as measurement range, medium compatibility, and contact capacity to ensure compatibility with existing systems. For example, chemical storage tanks require corrosion-resistant materials, while the food industry requires compliance with hygiene standards.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support or platform statistical information. Such suppliers can usually provide more stable product supply and technical support.
  • Float level switches are suitable for various scenarios such as water treatment, oil tank monitoring, or pharmaceutical industry. Before purchasing, it is necessary to clarify the installation method (side/top installation) and output signal type (switch/analog) and other detailed requirements.
  • For high-precision liquid level control scenarios, it is recommended to choose float level switches with temperature compensation or surge protection design, while paying attention to the actual application case data of suppliers in similar projects.

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

Float type water level switch is a commonly used water level controller, which is based on the action of buoyancy and gravity. When the liquid level changes, it will cause the float to rise or fall, thereby changing the state of the switch. This article introduces the working principle and application fields of float type water level switches.

Q

Float level switch is an instrument for measuring liquid level, which uses the position of the float to sense the height of the liquid level and outputs it to the control system through electrical signals. It is widely used in industrial, chemical, water treatment and other fields.
