The dosing of polymers requires the highest precision and reliability. VSE Volumentechnik supplied one of its existing customers with a high-temperature version of its screw meter for manufacturing polymer bars. One of the challenges in polymer metering is the extremely high viscosity of the materials, which in this case was around 20 million mPas, with an initial viscosity of up to 40 million mPas and an operating temperature of 120 °C. In addition, a weighing system is used in the machine that is very sensitive to vibration, and this can lead to incorrect measurements. The robust design of the volumetric sensor in the system supplied by VSE makes it ideal for use in the chemical industry, in particular for measuring high-viscosity media. The screw meter has a high flow rate of 4.5 kg/min at a density of 0.98. This enables it to provide precise results, even if it is exposed to vibration during the process. www.vse-flow.com
