Allengra showcased its innovative ALSONIC flow sensor family at the AHR Expo 2025 in Orlando, Florida. These ultrasonic-based sensors offer precise and efficient solutions for building monitoring, particularly in cooling and water consumption applications in large complexes such as airports, hotels and office buildings.

Optimal solutions for building monitoring and cooling

With the ALSONIC series, Allengra sets new standards in flow measurement. The sensors provide highlySource: Allengra accurate volumetric flow readings, enabling building operators and facility managers to analyze consumption patterns, identify inefficiencies, detect operational anomalies and minimize energy losses. In cooling applications, ALSONIC supports optimal control of cooling systems, enhancing the efficiency of HVAC systems. Its high turndown ratio of up to 1:5,000 allows for accurate measurement of both large and small flow rates with the same sensor size.

Technical highlights of the ALSONIC series

Allengra's ALSONIC flow sensors utilize ultrasonic technology to deliver highly precise flow measurements for water, water-glycol mixtures and many other liquids. They are available in durable brass, high-quality plastic versions as well as stainless steel.

✔ High measurement accuracy of ±2% of the current reading

✔ Measurement range: 0.04 gpm to 260 gpm (depending on the model, from 1/2 inch to 2 inches)

✔ Minimal pressure loss: Optimized for high efficiency in HVAC and cooling applications

✔ Wear-free: No moving parts, ensuring long service life

✔ Temperature measurement (-4° F to 230° F) with optional external temperature sensor for heat quantity measurement

✔ Glycol concentration measurement with automatic volumetric flow compensation

✔ Gas bubble detection for efficient venting and leak detection

✔ Easy integration: Analog and digital interfaces (0 V to 5 V, Modbus, Pulse) for seamless integration

✔ Pressure sensor: Upgrade your flow meter with a pressure sensor for a versatile all-in-one solution

✔ Protection class: IP44 (optional IP66) for demanding environments

✔ Energy-efficient: Power consumption under 10 mA (maximum 40 mA at startup)

These sensors are ideal for internal consumption allocation within large buildings, providing real-time data. This enables building operators and facility managers to precisely monitor water usage and cooling performance, optimizing their systems for greater efficiency and cost savings.
