METPOINT FLM: Sensor technology for volume flow measurement Every third compressor is only operated to compensate for air losses. These costs are largely avoidable. One possibility to avoid these costs is precise acquisition of the current volume flow. This then provides the basis for many important analyses, documentation and decisions. BEKO TECHNOLOGIES provides end-position monitoring with the FLM SF13 and SF53.  Is your production set up as optimally economical? You can only comprehensively answer this question when the current volume flowrequirement for your compressed air has been identified. This can be evaluated for you by the FLM volume flow measuring system and thereby provides you with the data basis you need for intelligent energy management. Identify potential savings, overloads and weak points in your system to improve its efficiency. By measuring the actual flow to the various production units, you are in a position to make decisions based on facts. At the same time, the FLM lets them know whether there are any leaks in their system. The measurement thereby provides you with all the necessary data you need to jointly coordinate components in the best possible way and design systems economically.  The FLM SF13 variant is available with measuring sections of different diameters and comes with a calibration certificate for the selected pipe diameter. The METPOINT FLM SF53 is pre-calibrated as a universal sensor to a pipe diameter of 53.1 mm, but can be adjusted/calibrated to other diameters on customer request. METPOINT®️ FLM with LED The less expensive LED variant indicates the need for a new calibration (annually). Please note: The sensor configuration can only be done during production or later via the BDL datalogger Function METPOINT®️ FLM  Two temperature sensors are installed in series in the direction of flow. The first temperature sensor measures the current process temperature of the compressed air, while the second sensor is electrically heated to a temperature that is 40 K higher than that of the first sensor. Higher volume flows results in a quicker drop in temperature at the sensors, so that the electric heater of the second sensor must increase its heat output. The electric energy required to maintain the temperature difference is proportional to the volume flow. This energy consumption is converted to provide the relevant flow measurements.

The flow meter VA 500 with display will have a built-in screen that shows real-time flow rate readings, totalized flow volume, and possibly other relevant information. This makes it easier for the user to monitor and track the flow measurements directly on the device. On the other hand, the flow meter VA 500 without display will not have a built-in screen, so the user will need to connect it to an external display or monitoring system to view the flow rate and other data. This may require additional equipment and setup but can be a cost-effective option for applications where a separate display is already available. In summary, the main difference is the presence or absence of a display screen on the flow meter itself, which affects how the flow data is displayed and accessed by the user.

Here's how the VA 500 flow meter works to monitor compressed air: Principle of Operation: The VA 500 flow meter measures the flow rate of compressed air by utilizing two temperature sensors and a heater element within the flow sensor probe. One sensor measures the actual gas temperature, while the other sensor is heated to a constant temperature above the gas temperature. Thermal Dispersion: As the compressed air flows past the heated sensor, heat is transferred from the sensor to the gas. The amount of heat transferred is directly proportional to the mass flow rate of the compressed air. The difference in temperature between the two sensors is used to calculate the flow rate of the compressed air. Signal Processing: The VA 500 flow meter processes the temperature difference signal and converts it into a digital output representing the actual flow rate of the compressed air in standard units such as cubic feet per minute (CFM) or liters per minute (LPM). Monitoring and Display: The VA 500 flow meter provides real-time monitoring of the compressed air flow rate through a digital display or communication interface. Operators can view and track the flow rate data to ensure that the system is operating within specified parameters. Features and Benefits: The VA 500 flow meter offers high accuracy, fast response time, and low pressure drop, making it suitable for a wide range of compressed air applications. It can help operators optimize system performance, detect leaks, and improve energy efficiency by providing accurate flow rate measurements. Overall, the VA 500 flow meter for compressed air monitoring is a reliable and effective tool for measuring and monitoring the flow rate of compressed air in industrial applications, helping operators maintain system efficiency and reduce operational costs.

The ISO air quality chart provides guidelines for the maximum allowable levels of contaminants in compressed air systems based on the ISO 8573 standard. The ISO 8573 standard specifies purity classes for different contaminants such as particles, water, and oil in compressed air systems. When it comes to an inline flow meter like the VA 520 with a thread connection, the thread type and size can have an impact on the air quality in a compressed air system. The thread connection of the flow meter can potentially introduce contaminants into the system if not properly sealed or if the thread material is not compatible with the air quality requirements. It is important to ensure that the thread connection of the flow meter is properly sealed and does not introduce contaminants into the system. Additionally, the material of the thread should be compatible with the air quality requirements to prevent any contamination issues. When selecting an inline flow meter like the VA 520 for a compressed air system, it is essential to consider the thread connection type, size, and material to ensure that it does not negatively impact the air quality according to the ISO 8573 standard. It is recommended to consult the manufacturer's specifications and guidelines to ensure that the flow meter meets the air quality requirements of the system.
