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.

Utilizing conventional flow meters may not be the optimal choice for most applications.

There are a multitude of factors that contribute to the overall lower efficiency rates that they provide, but here are a few 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.  Durability in Harsh Conditions: Mechanical flow meters are less durable in harsh environments, such as those with high temperatures, vibrations, or corrosive fluids, leading to a premature wear or failure.

    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.

Micro Flow Meter

Allengra is known for its reliable Ultrasonic Flow Meters, no matter the application they may encounter.

The Micro Flow Meter stands as a prime candidate for precision and efficiency. Compared to conventional Micro Flow Meters, these are a few 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.  Durability in Harsh Conditions: Allengra's Micro Flow Meter is tailored with a robust design, with wetted materials such as PPS, Stainless Steel 1.4301, Silicone Rubber, it's fit to face challenging conditions. 

    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.
