Solution | Dual choice of vortex flow sensors and flow switches to address flow monitoring challenges in different industrial scenarios

Plan One: High-precision flow measurement using vortex street flow sensors

Principle and Features

The vortex flow sensor operates based on the Karman vortex street effect, measuring flow rate by detecting the frequency of vortices generated when fluid flows past an obstacle. This design eliminates reliance on the fluid's conductivity, making it highly effective for measuring media such as water, gases, and steam.

Product Features

? Dual Monitoring of Flow and Temperature: Simultaneously monitors flow rate and temperature, with three selectable flow ranges (2–16 L/min, 5–40 L/min, 10–100 L/min) and a temperature range of 0–100°C. Accuracy is ±3% of full scale for flow and ±1°C for temperature.

? High-Resolution IPS Display: Supports four-way orientation switching, ensuring clear data readability even in complex installation conditions.

? Standardized Interface and Communication: Equipped with an M12 A-coded 4-pin IO-Link interface, enabling remote parameter configuration and real-time data reading via ISDU (Index Service Data Unit).

? Cumulative Flow Recording: Supports flow recording up to 99,999 L or m3, facilitating data analysis and traceability.

? Flexible Adaptability Design: Offers multiple thread specifications to accommodate different pipe diameters. Switching configurations support normally open/normally closed, NPN/PNP/push-pull options to meet diverse application needs.

Application scenarios

Industrial pure water monitoring: Vortex flow sensors are particularly suitable for measuring low-conductivity fluids such as industrial pure water, solving the instability issues of electromagnetic flow meters in such scenarios.

? Flow and temperature management in mold temperature controllers: By real-time monitoring of medium flow and temperature, optimizing pump speed and valve control ensures uniform mold temperature, improving product quality.

Solution Two: Real-time water flow monitoring using flow switches

Principle and Features#?

Flow switches operate based on the principle of thermal loss, detecting the flow state of fluid within the pipeline and providing rapid switch signal outputs. They feature a simple structure and stable performance, making them ideal choices for cooling systems and lubrication systems.

Product Highlights#?

? Real-time monitoring of water flow status: Utilizing the thermal loss principle, flow switches can accurately detect the presence of water flow within the pipe. When the flow rate falls below the preset value, the sensor quickly issues an alarm signal, ensuring system safety.

? 304/316L stainless steel construction: The housing is made of 304 stainless steel, while the probe uses food-grade 316L stainless steel, offering excellent corrosion resistance and hygiene, suitable for various media including industrial cooling water and lubricating oils.

?

Cooling water flow monitoring: In large cooling systems, ensure that the flow state of dozens of pipelines is normal to prevent equipment damage due to cooling failure.

? Simple flow status monitoring: Suitable for basic monitoring scenarios of water flow and oil flow in industrial equipment, providing an economical and efficient solution.

Solution Selection Recommendations

1. Real-time monitoring requirement for fluid flow: For real-time monitoring of fluid flow, such as in cooling systems and lubrication systems, it is recommended to use flow switches based on thermal loss principles. These devices are cost-effective and easy to install.

2. High-precision measurement requirement: For high-precision measurements of flow and temperature, especially in applications involving industrial pure water or mold temperature controllers, it is recommended to use small-volume vortex flow sensors. These sensors offer high adaptability and intelligent communication capabilities, meeting the demands of Industry 4.0.

3. Hybrid scenarios: For complex industrial systems requiring comprehensive solutions, both types of sensors can be used together:

- Flow switches for state monitoring;

- Vortex flow sensors for high-precision measurement and data recording.
