Table 1: Cox Exact Meter sectional view data
The Cox Exact design uses a tie-bolt concept, where the rotors are suspended in the
housing on a common stem The stem is threaded into the downstream support, except
for the 1/4 in (84) and 3/8 in (86) sizes where it is captured on both ends with a nut Stem
nuts are held in place with high temperature locking compound The Cox Exact turbine
flow meter does not contain snap rings or retaining rings that can be dislodged by shock
or vibration
Cox Exact flow meters use an embedded, radio frequency pickup coil that is not field-
replaceable The low profile design of these meters requires a specialized potted pickup
that must be returned to Badger Meter, if it requires service or replacement This type of
embedded pickup is vibration resistant and allows for a compact, overall meter size
