Hi everybody,

This is a general question
For pressure and DP tappings, what kind of purging(if provided) do you recommend - continuous or intermittent ? Any information on this would be keenly appreciated.

TIA

dear mr.P.V.Raman:
Intermittent purging is superior to continnuous in the sense, blast of medium is used with time intervals to safeguard the impulse pipe from
getting clogged by particulate matter.

We using both continuous and intermittent/pulsed purging on a number of systems.

In fact, we are currently implementing a combined system for monitoring air transport lines on a flyash system, where a fixed flow low level purge is used to help stablize the vacuum signal, and a solenoid switched high pressure purge pulse system is used to "blast" the process connections
clean.
