Ahlborn FVA 645 GVx stainless steel liquid flow sensor

The Ahlborn FVA 645 GVx is a stainless steel flow sensor for liquids. The design incorporates no moving parts and has integrated temperature measurement.

The flow sensor is built to optimise durability - the measuring section uses a robust, industry-quality stainless steel that increases the strength of the flow sensor. The device is designed without any moving parts, meaning the chance of wear and tear to the flow sensor is greatly reduced. The flow sensor also offers a low pressure loss, increasing the accuracy of measurement. The accuracy is also bolstered by the flow sensor’s fast reaction time. The device is optimised for measuring heat output in heating systems and cooling plants.

Using the Karman vortex street measuring principle, the flow sensor supports several measuring ranges from 1-12 up to 10-200 L/min (other ranges also available) and has an error ±1 K at a temperature range of 25-80°C and ±2 K at a temperature range of 0-100°C.
