Real World Coolant Circulation Monitoring
Coolant systems play a significant role in the overall efficiency and emissions performance of an engine. With tightening worldwide emissions standards for passenger and commercial vehicles, understanding and optimising engine coolant circulation performance is vital.
Traditional lab-grade flow meters allow engine developers to understand coolant flow dynamics within a controlled lab environment, however the size, weight and complexity of the devices make them unsuitable for ‘real-world’ in-vehicle tests.
Sentronics’ technology makes it possible for the first time to use the same device on the bench and on the road, providing lab-grade measurement accuracy in a package small and light enough to fit within an engine bay without affecting vehicle dynamics.
FlowSonic in-vehicle Coolant Circulation Monitoring
Developed specifically for in-vehicle fluid flow measurement, FlowSonic is a compact coolant flow meter offering laboratory-grade measurement precision in a ‘plug and play’ package that can be installed in minutes.
The device isn’t intended to replace traditional laboratory measurement equipment; rather to work in harmony with it to understand how lab results translate in real-world dynamic environments. Reference values can be collected in the lab, then the device can be disconnected and installed on the vehicle for real-world performance tests quickly and simply.
FlowSonic represents a significant step forward in automotive coolant circulation performance monitoring, giving engineers an unprecedented understanding of performance where it really matters – on the road.
Breakthrough Ultrasonic Measurement Technology
FlowSonic represents a breakthrough in ultrasonic flow measurement technology, using innovative digital processing techniques to measure ultrasonic time of flight with unprecedented accuracy.
It achieves levels of laboratory-grade precision and stability typically associated with bulky and expensive mechanical meters, in a package small enough to install in an engine bay.
FlowSonic incorporates all the necessary flow conditioning within its compact body, eliminating any need for lengthy pipework as part of the installation. It is unaffected by mounting orientation and maintains measurement performance when subjected to pulsed flow, vibration and changes in temperature.
FlowSonic LF Typical Calibration Performance
±0.5% accuracy maintained over a 500:1 turndown ratio (traceable to UKAS ISO/IEC 17025:2017).
Key Features & Benefits
FlowSonic allows true ‘real world’ coolant circulation performance to be understood. Here are just a few of the major benefits of adopting this solution.
Measure at Point of Flow
FlowSonic can be easily installed within a vehicle’s engine bay. By measuring at the point of flow, measurement errors introduced by additional pipework are eliminated.
FlowSonic brings lab-standard accuracy and stability to road testing, featuring a class-leading 500:1 turndown ratio, and 2kHz measurement rate for precision transient flow data.
FlowSonic facilitates easy reconciliation of laboratory and road test coolant circulation data, allowing engineers to understand how lab-based data translates to dynamic performance.
Vehicle to Bench Portability
FlowSonic is compact and lightweight, providing unprecedented installation flexibility. The device can be installed in any orientation and can be moved between vehicle and test bed in minutes.
Compared to traditional laboratory equipment, FlowSonic is a truly low-cost instrument, delivering a cost-effective solution to on-vehicle coolant circulation measurement.
Configurable Output Formats
FlowSonic offers data communication options to suit your existing test system, with CAN, digital TTL pulse, and analogue outputs all available.
UKAS Accredited Calibration
All Sentronics Flow Meters are available with an advanced, customisable calibration accredited to UKAS ISO/IEC 17025:2017
