Overtightening the plastic ties may col lapse the reference tube in the cable blocking it The spring ring may need anchoring Under conditions of high velocity greater than 5 feet per second or 1 5 meters per second the ring may not have sufficient outward spring force to maintain a tight fit inside the pipe The ring may start to lift off the bottom of the pipe in a waving fashion or may even be carried downstream This problem is more prevalent in the larger diameter pipes 10 12 and 15 and in pipes with smooth inside surfaces such as plastic pipes If any of these conditions are present or if movement of the mounting ring is detected or suspected you must anchor the ring in place You can do this by setting screws through the ring into the pipe or by other appropriate means If there is a problem with the smaller diameter rings it may be suf ficient to simply increase the outward spring force of the ring by bending it into a less round configuration For pipes larger than 15 in diameter Teledyne Isco offers the adjustable Scissors Ring also known as the Universal Mounting Ring This device consists of two or more metal strips that lock together with tabs to form a single assembly There is a base section where the sensors are mounted one or more extension sections usually and a scissors section at the top that expands the entire assembly and tightens it inside the pipe The scissors mechanism includes a long screw
