Our Products

Allengra's ultrasonic time-of-flight sensors have no moving parts, eliminating wear, drift, and maintenance required by turbine or paddle wheel meters. By measuring acoustic transit time in both flow directions, they deliver high accuracy across wide ranges without pressure drop or obstruction. This non-invasive design ensures long-term stability and reliability for demanding OEM applications where total cost of ownership matters.

Our sensors are optimized for clean to slightly contaminated liquids with predictable acoustic properties including water, glycol mixtures, oils, and many industrial fluids. Performance depends on acoustic impedance, viscosity, and particle content; highly aerated, multiphase, or opaque slurries may require application review. We work closely with OEMs during the specification phase to validate compatibility and ensure optimal sensor configuration for each fluid type.

Allengra sensors are factory-calibrated and deliver accurate measurements immediately upon installation in most applications. Field calibration is not required under normal operating conditions, though verification against a reference standard is recommended during commissioning for critical systems. Our time-of-flight principle inherently compensates for temperature and ensures measurement stability over the product's operational life.

Yes. Allengra sensors support multiple industry-standard output formats including I²C, UART, PWM, and analog signals, enabling seamless integration with PLCs, microcontrollers, SCADA systems, and embedded platforms. We provide comprehensive technical documentation, reference designs, installation kits, and application support to accelerate integration timelines.

With no moving parts and robust solid-state construction, Allengra sensors are designed for operational lifespans exceeding 10 years in typical industrial and HVAC environments. Actual lifespan depends on operating conditions such as fluid compatibility, temperature cycling, and installation quality. Our sensors undergo extensive endurance testing to ensure they meet the reliability expectations of mission-critical applications.
