Target Flow Switch As a flow monitoring and control device widely used in industrial automation, its performance and reliability directly affect the stability and safety of the production process. Therefore, choosing a manufacturer that meets industry standards and regulations is crucial. This article will discuss in detail how to understand and evaluate Target Flow Switch from the perspective of industry standards and regulations target flow switch manufacturers 。

I. Basic Principles and Applications of Target Flow Switches

Target flow switches detect flow by measuring the impact force of the fluid on the target plate. When fluid flows past the target plate, the force on the target plate is proportional to the fluid velocity. A sensor converts this force into an electrical signal, thereby achieving flow monitoring and control. Target flow switches are widely used in the petroleum, chemical, water treatment, and power industries to prevent pump idling, pipe dry burning, and other dangerous situations.

II. Main Industry Standards for Target Flow Switches

1. International Standards

ISO 5167-1:2003 : This standard specifies the dimensions, installation, and usage requirements for orifice plates, nozzles, and Venturi tubes used in flow measurement. Although mainly aimed at differential pressure flow meters, it also provides some reference value for the design and calibration of target flow switches.

IEC 61508:2010 : Functional safety standard applicable to all types of electrical/electronic/programmable electronic safety-related systems. As a safety-related device, the design and manufacturing of target flow switches must meet the requirements of this standard.

2. National Standards

GB/T 2624-2006 : Equivalent to ISO 5167, it specifies the technical requirements for orifice plates, nozzles, and Venturi tubes used in flow measurement and is applicable to the design and calibration of target flow switches.

GB/T 16808-2008 : Industrial automation systems and integration industrial automation instrument systems, specifying the design, installation, commissioning, and maintenance requirements for industrial automation instrument systems. Target flow switches, as part of the instrument system, must comply with this standard.

3. Industry Standards

JB/T 6844-2018 : Target flow meter, specifying the technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of target flow meters. It is the main reference standard for the design and manufacturing of target flow switches.

JB/T 9268-2018 : Flow switches for industrial automation instruments, specifying the classification, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of flow switches, applicable to target flow switches.

III. How to Evaluate target flow switch manufacturers

1. Certification and Qualifications

Production Process : Whether the production equipment is advanced, the process flow is reasonable, and the quality control is strict.

Testing Equipment : Whether it has complete testing equipment, such as flow calibration devices, high and low temperature test chambers, and vibration test platforms.

Patented Technology : Whether it has independently owned intellectual property rights and patented technologies, reflecting the manufacturer's innovation capabilities and technical level.

3. Product Quality

Material Selection : Whether the materials of key components such as the target plate and sensor are corrosion-resistant and high-temperature resistant and meet the requirements of the usage environment.

Accuracy and Stability : Whether the product's measurement accuracy, repeatability, and long-term stability meet industry standards.

Protection Level : Such as IP65, IP67, etc., ensuring that the product can still work normally in harsh environments.

Service Life : Whether the product's mean time between failures (MTBF) reaches the industry average.

4. Service Capabilities

Pre-sales Service : Whether it provides detailed product selection guidance, technical solution design, and on-site survey services.

In-sales Service : Whether it provides installation guidance, debugging training, and on-site technical support.

After-sales Service : Whether it provides free repair within the warranty period, paid repair and spare parts supply services outside the warranty period.

Response Speed : Whether the response and handling speed to customer issues is timely.

IV. Case Analysis
