Abstract
A tubular connected series of biofilm samplers is provided for monitoring biofouling by microorganisms in a continuous flow stream. Tubular bypasses are provided around each sampler, so that each sampler is removable for inspection of biofouling without interruption of the continuous flow stream. In addition, each sampler has a contoured surface which is in contact with the continuous flow stream and which is flush with the inner surface of the tubulars connecting the samplers.
