Creative sensor technology expands its flow sensor offerings with a new saddle type flow sensor available for 3 in., 4 in. and 6 in. PVC pipe sizes. S Series sensors include the mounting saddle. Sensor depth and alignment are preset. No measuring tools and alignment rods are necessary. Simply drill a 1-3/4 in. hole in the pipe and attach the two halves or the saddle. The saddle type sensor mounts on PVC piping systems using a wedge to hold the sections together. Prior to installation, an opening is drilled in the pipe allowing the sensor insert to position the impeller inside the pipe. Designed by the same team who created the original irrigation impeller flow sensor, CST's sensor is completely new, not a redesign. The sensor features a digital output signal proportional to flow. The output signal duplicates existing impeller flow sensor signals making the FSI series sensor compatible with all manufacturer's control products. The pulse signal will travel up to 2000 ft. without amplification. The insert, held in place with a retaining nut, contains the detection circuitry and carries the unique four-bladed ultra light impeller on a transverse axle.
