Description
The AS009 flow meter with a DN 20 internal diameter measures flow rates for a 5.0 to 85.0 l/min range. Temperatures of between -25°C and +125°C can also be measured thanks to the integrated Pt1000 element. The measurements are output as a 4…20 mA signal via a 3-pole M12 plug. The sensor is inserted between two pipes as an inline device and screwed tight using a G1 external thread. The compact design enables simple installation in confined spaces. The high-quality plastic housing and the simple yet robust design of the sensor make it a very cost-effective alternative compared to sensors with a metal housing. AS009 utilises the vortex principle for flow metering. A damming body creates vortices that are proportional to the flow velocity. The measuring method functions without any moving parts and is thus insensitive to soiling. The flow meter is suitable for hot water, drinking water and for all water-based, liquid media. Typical applications are industrial heating and cooling circuits.
