Ring, Sensor, and Special Installations 4-5
Ring Assembly
The flow sensors are mounted on a stainless steel ring which is installed in the sewer
pipe. There are several different ring sizes. Each ring is adjustable within about three
inches to fit different pipes. Rings are designed for the secure installation of
ultrasonic, velocity, and pressure sensors.
Note: The last topic in this chapter, “Special Installations,” deals with
installing equipment in non-standard pipes. For example, pipes which are not
round and pipes greater than 48 in. (a standard stainless steel ring cannot be
used) require a special installation. Refer to page 4-20 for more information
about special installations.
Parts List The parts of the spreader mechanism come assembled. The ring assembly
consists of
l one adjustable stainless steel ring,
l one ultrasonic sensor mount,
l one stabilizer sliding bracket, and
l one spreader assembly (which includes a spreader bolt, shoulder bolt, and
spreader bar assembly; two spreader mechanism attachment screws; two hex
nuts; and two large washers).
Tool List Ring assembly requires the following tools:
l a medium sized Phillips head screw driver and
l a 1/2 in. nut driver or wrench (ADS part number F35-0063).
Note: The ring has a detachable crank handle. Any crew using the new ring
will need to have two detachable crank handles, one with an 18 in. (46 cm)
shaft, ADS part number I10-0012, and one with a 24 in. (61 cm) shaft, ADS
part number I10-0013. You may substitute a 1/2 in. deepwell socket (ADS
part number F35-0094) with a compatible ratchet.
Assembling the Ring
Perform the following steps to assemble an adjustable, stainless steel ring.
1. Insert the spreader mechanism screw through the hole in the center of the ring
stabilizer. Ensure that the head of the screw fits into the counter sink hole.
