The BEC PM1 enables a volumetric or time based control of
BERMAD's On/Off control valves that are used for purging pipe's
dead ends, refreshing reservoirs and other such On/Off applications.
This chapter describes the Dead-end Pipes Purging Application
Settings.
Dead-end Pipes Purging Application
Settings
Due to operational conditions, in some municipal and industrial
water systems, there is a need for periodic purging of the systems
dead-ends of pipes for refreshing the water supply. BERMAD’s
control valves equipped with BEC PM1 controllers can be installed
in these systems. BERMAD’s Dead-end Pipes Purging Application
accounts for the purging out of the system. This task is automatically
performed based on three major parameters:
1. Purging interval - set at specific days of the week or
as day intervals
2. Amount of purged water - set by operation time or by volume
3. Start time - set for the operation day
(with up to three start times per such day)
The following examples depict three typical scenarios:
