What does a flow guard offer for gas?

A Flow, often also referred to as flow guards or gas flow guards, monitors the flow or flow of gas or air in a pipeline system precisely and precisely. If the gas flow falls under a preset value or exceeds it, the flow guard sends out a signal that trigger an alarm message. If this is the case, you have enough time to close the affected valve or to initiate further protective measures.

How does an airflow guard work?

In the case of air flow monitoring or monitoring gases, the flow guard continuously checks the flow of the medium. The exact functionality depends on the type of sensor used. Modern sensors are based on physical principles in order to recognize changes in the flow quickly and precisely. The probably most frequently used procedure for a flow guard is that thermal principle. This method is used to use two thermo elements or temperature sensors. While one sensor is heated to a target value, the other focuses on the ambient temperature of the gas. The flow guard measures the temperature difference between the two sensors proportionally to the gas flow speed. If the current falls under the thresholds you have defined or exceeds it, the flow guard recognizes this and triggers a corresponding action, be it an alarm or the automatic closing of a valve.

Another principle that can be used by a flow guard uses one mechanical sensor, often back in the form of a whipped wheel that is located in the gas flow. When gas or air flows through the pipe, it turns the whipped wheel. A sensor monitors the rotary speed of the impact wheel. The speed is a direct measure of the gas flow. If the river falls under a certain value or exceeds it, a signal also triggers a signal in the case of the air flow guard.

There are also other types of sensor, such as those based on acoustic or magnetic-inductive principles. Regardless of the specific principle, the basic function of the flow guard is always the same: it continuously monitors the flow of matter and intervenes if it does not meet the defined requirements. This ensures that the gas or air flow in a system remains always within safe and efficient limits.

What are the advantages of air flow monitoring?

The use of a flow guard has different advantages for different areas of application and claims. If you rely on reliable gas and air currents, it is advisable to think about the purchase of air flow guards. In many systems, especially if dangerous or combustible gases are involved, an unexpected decline or increase in air flow can lead to dangerous situations. The airflow guard recognizes such deviations early and you can react immediately. If an air flow is crucial for the quality of the end product in industrial processes or laboratories or it is about protecting against overheating of sensitive devices, a flow guard for air or gas also shows its remarkable performance in this case.

Another advantage of air flow monitoring is that the air or the gases circulates efficiently and with the correct setting. In this case, the flow guard convinces as Energy efficiency-Tror and supports them in saving energy costs. Furthermore, the usually significantly higher costs for manual measurement are eliminated, which also reduces the binding of employee capacities.

With a flow guard, the threshold values ​​can usually be set individually, which guarantees you a maximum of flexibility. This gives you the opportunity to meet different application conditions and requirements.

Even with regard to maintenance, a flow guard does reliable work. If, for example, blocked filters are the cause of the sudden decline in the air flow or if a fan is threatened, the difficulties can be recognized faster and they can plan and carry out accordingly preventive maintenance work.

Overall, increases one Flow The reliability, security and efficiency of your systems in which control and monitoring of the air flow is of central importance.

Where are the areas of application of flow guards?

Sure, it will not surprise you that a flow guards with its many advantages will be used in different areas of application. Especially in industry, the devices are considered indispensable when it comes to the flow measurement of gases and air flows.

The areas of application include:

• Ventilation and air conditioning systems (HVAC) to ensure the desired room temperature and air quality.
• Pour to prevent contamination.
• Laborers for the proper function of deduction systems.
• Industrial process control for product quality and security.
• The boiler and heating systems so that there is sufficient combustion air and exhaust gases are properly removed.
• Server rooms and data centers to avoid overheating the hardware.
• Mining and tunnel construction, to monitor the fresh air supply and the deduction of exhaust gases.

Certainly just a few examples in which a flow guard or Air flow plays a crucial role.

Our selection of air flow guards

In our Product categories Discover a large selection of flow guards and Air flow guards who meet their specific requirements.

One of our most popular models is the Evaluation unit air flow guards NLSW45-3 As a universal flow guard with a switching output for control cabinet installation. The tree pattern was checked by TÜV Nord according to DIN EN 61010-1: 2011-07. The measurement area of ​​the flow guard is 0.1 ... 30 m/s. Commissioning is easy and quick. The compact flow guards including Sensor RLSW4R with a relay output (NO) and a measuring range of gases with infinitely variable setting between 0.1 ... 15 m/s offers an alternative. The robust sensor structure, the protection class IP67 and the handy dimensions should be emphasized in this flow guard.

We also have variants such as the flow guards with the sensor RLSW4A M8 including analog output for measuring range of gases between 0.1 ... 30 m/s and the flow monitor RLSW6AR with two relay outputs for HVAC applications. This includes sensors and an automatic reset.
