In 2009 Allengra released the first generation of Ultrasonic Flow Meters for High Temperature applications for Water, Oils, Glycol and other liquids especially in the plastic injection industry for temperature control.
Based on ALSONIC, the new generation, of High Temperature Flow meters covers temperatures of up to 240°C. The body made exclusively out of stainless steel with no internal sealings is robust to handle long term temperatures of 220°C, and pressures of 40 bars. For short term peaks (<1 min) 240°C imposes no problem.
Durable & Versatile
Designed to meet the diverse demands of industrial and mobile applications, this ultrasonic flowmeter offers an exceptional range of features that redefine efficiency and reliability in liquids measurement:
Up to 220°C ( <1 min @ 240°C) – the used materials basically stainless steel allow an excellent temperature behaviour up to 240°C
Accuracy +-2% - the ultrasonic technology allows a very high and stable level of long-term accuracy with no drift
Compact Form – due to the compact form the sensor can be used in distribution groups
Robust against vibrations – the Allengra design is based on the long experience in mobile applications including motorsports
Stationary applications - In stand-alone form as compact sensor solution
Mobile applications – On board flow metering for cooling liquids in automotive
Very low pressure drop – The sensor simulates a straight pipe leading to the lowest possible pressure drop
No need for straight pipe before and after the sensor – In case of complicated pipe geometries the sensor can be delivered with an internal flow straightener which dampens the effect of the inlet
Can be installed in any orientation – The accuracy is not influenced by the position
Non invasive technology – No obstacles in the flow, maintaining low pressure drop
Gas Bubble detection – This feature is steadily controlling the gas (air) bubbles that can be generated due to overheating or lack of pressure which would reduce the efficiency of the system - can occur in temperature control units
Integrated temperature sensor
Short response time of flow and temperature – In cases of tempering a short response time is decisive as a fast reaction can mitigate damages
Optional pressure sensor – To avoid underpressure and overpressure an optional pressure sensor with a short reaction time completes the package
Suitable for all liquids - The sensor can be used for conductive liquids as water as well as non-conductive liquids such as oils
Outputs: such as MODBUS, Analog – a wide range of communication interfaces are available
Energy Metering – Monitoring the energy to calculate the overall efficiency of the temperature control units
