Bio fouling indirect and direct combined metering monitor consists of a continuous film growth and friction factor meter responding to variable heat transfer resistance

The bio fouling indirect and direct combined metering monitor comprises a continuous evaluator of the growth of bio fouling film in the tubes of a tube bundle. The heat exchanger tubes are also monitored indirectly by measuring the friction factor and the resistance to heat transfer. The heat exchange is between two fluids, one of which contains microorganisms.

El sistema valora en continuo el crecimiento del biofouling adherido en la superficie interna del tubo de un intercambiador y consta de dos partes diferenciales: la que supervisa el biofouling mediante un sistema directo (muestra de película biológica), y la que controla este fenómeno no deseable de forma indirecta, por medio de la medida del factor de fricción y de la resistencia a la transferencia de calor.
