Purchasing Guide

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

  • For procurement requirements that require the use of flow switches, it is recommended to prioritize confirming the medium type and flow range, ensuring that the measurement accuracy of the switch matches the pipeline pressure level, and avoiding monitoring failure due to parameter deviations.
  • In industrial water treatment or HVAC systems, flow switches with analog signal outputs can be considered for integration into automation control networks, while the food industry needs to pay attention to material compliance to adapt to hygiene level scenarios.
  • When selecting suppliers, priority should be given to product matching, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information to reduce procurement risks.
  • If the application scenario involves high-frequency vibration environments (such as pump stations), it is recommended to choose a flow switch with mechanical protection design and verify whether the anti vibration parameters provided by the supplier meet the requirements of the on-site working conditions.

Knowledge Base

Q

This article comprehensively analyzes how to choose a flow switch suitable for industrial scenarios from three aspects: the working principle, key parameters, and selection precautions of flow switches, helping readers avoid common misunderstandings.

Q

This article introduces the application of microwave flow switches in industrial automation, environmental monitoring, and smart homes, analyzes the advantages and typical usage scenarios of non-contact measurement, and helps readers understand the practical value of this technology.

Q

The LYFS series flow switch is mainly used for liquid flow monitoring and switch output in pipelines. Its solid structure and stable performance can be widely used in the cooling and lubrication systems of compressors, motors, generators, rolling mills, conveyors, and other machines. When the flow exceeds or falls below the preset switch point, it can output a switch control signal.
