Precision Perfected: Allengra’s Second-Generation Micro Flow Meters

We are thrilled to announce the launch of our second-generation Ultrasonic Micro Flow Meter, marking a significant milestone in our continuous innovation process.

Coming in two variants OD6 and OD8 with a flow range from 0.02 – 10 l/m, this flow meter is perfectly suited for a vast number of applications, such as coffee machines, robotic arm spray nozzle, beverage dispensers, automotive applications etc.

Disadvantages of using a conventional micro flow meter: 

    1.  Mechanical Wear and Tear: A conventional micro flow meter relies on mechanical moving components to measure the fluid’s flow. Overtime, these moving parts can degrade, leading to a significant decreased accuracy, increased maintenance requirements and a higher probability of mechanical failure.

    2.  Lower Accuracy and Precision: The accuracy of such flow meters can be limited, especially at very low flow rates. Factors such as friction, mechanical inertia or fluid viscosity can contribute to inaccuracies on the provided data.

    3.  Sensitivity to Fluid Changes: Viscosity, density and temperature can change, and such flow meters are sensitive to these factors and can impact the accuracy of the flow measurement.

    4.  Installation and Alignment: When it comes to mechanical parts, the correct alignment and installation is crucial for the optimal accurate measurement. Misalignment can lead to significant error and inconsistencies.

Advantages of using Allengra’s Micro Flow Meter:

    1.  No Mechanical Wear and Tear: By utilizing Ultrasonic Technology, there is no mechanical moving parts within the flow meter’s casing.

    2.  Higher Accuracy and Precision: Such low flow rates are not an impediment. This flow meter provides a ± 2% accuracy of the measured value.

    3.  No Sensitivity to Fluid Changes: The measuring process is calculated with the time-of-flight principle, not encountering the actual fluid. Therefore, sudden changes within the fluid property are not an issue for the Micro Flow Meter.

    4.  Installation and Alignment: Due to its compact and robust design, along with push-fit male connection, this flow meter effortlessly integrates within any environment.

Versatility and Performance 

A non-intrusive Ultrasonic Flow Meter with a hygienic and no-dead-space design built out of high-end materials that prevent bacterial growth, this Micro Flow Meter is compliant with EU regulations 1935/2004, 10/2011, NSF51 and FDA.  

The Micro Flow Meter features state-of-the-art MODBUS RS485 and I²C digital communication interfaces, ensuring that it integrates effortlessly with sophisticated automation systems. Additionally, the device provides a consecrated analog interface with Pulse and 0.5 – 4.5 V outputs for compatibility with simpler control systems. 

Key Features:

    -  Gas Bubble Detection           

      This Micro Flow Meter can detect the sudden absence of liquid within a tank or even entrained air within a system that can prevent excessive wear of components. Furthermore, it can detect no properly sealed hydraulic connections or any irregularities within the fluid’s composition.

    -  Medium Detection 

      Monitors the fluid in real-time by continuously tracking the liquid type, thus it detects the concentration through its multi-stage sensing that can distinguish different mediums. 

    -  High-Speed Temperature Measurement  

      Utilizes a state-of-the-art temperature measurement via Ultrasonic Technology. Conventional temperature sensors tend to have a T90 < 2s or in certain cases, even more. Allengra’s Micro Flow Meter provides a remarkable T90 < 0.25s response time without interfering with precision.
