ScioSense
ScioSense manufactures high-performance environmental and flow sensors for a variety of different markets. The ScioSense portfolio of environmental and flow sensors is aimed at demanding users in the automotive, industrial, building automation, and consumer device markets which want compact, low-power board-mount products and superior sensor performance.
The high accuracy, precision and stability of ScioSense products is the result of four decades of experience in sensor development. The products also benefit from the deployment of innovative technologies such as the TrueVOC™ quad-hotplate gas sensor element in the ENS160 air quality sensor, and the phase-jump measurement technique in the AS6040 and AS6031 ultrasonic flow converters.

An ultrasonic flow converter for the next generation of ultrasonic water and heat meters
The AS6031F1 includes an ultrasonic flow measurement front end with programmable amplifier, a low-power 32-bit processor and firmware for converting the sensor’s analog outputs to precise measurements of cold water flow, volume and temperature. This simplifies the design of ultrasonic water and heat meters, combining the precise measurement and the complex flow calculation. It provides outstanding low-flow detection capability due to excellent zero-flow drift.
The AS6031F1 allows designers to build robust systems which offer very accurate measurements of water flow and volume, making it suitable for use in water metering applications that are regulated by law. The device measures the difference in the time it takes ultrasound waves to travel upstream and downstream, providing extremely repeatable, temperature-stable and accurate timing measurements. The very high precision and stability of its flow measurements mean that it is able to detect water leakage rates as low as 0.5 liters per hour in a good DN20 meter, many times lower than the minimum water flow measured by today’s widely used mechanical water meters.
The AS6031F1 provides an SPI interface to an external microcontroller, or a pulse interface to emulate a conventional mechanical water meter’s signals. Users of the Sciosense device may therefore replace their former mechanical flow measurement system with a modern non-invasive flow meter without the need to rewrite their application software.
Benefits:
- Single-chip solution provided ready flow information
- System design compatible with mechanical meters
- High flexibility in choice for external μP handling communication and further data management
- Precision down to low flow rates
- Leakage detection
