4.7 Connecting Sample and Reagents

4.7.1 Connecting Sample Inlet and Drain Line(s)

The sample pot fills with sample and over-flows at the top to
maintain a constant head from where sample is taken to be
measured.
B
The sample drain line(s)
routed to maintain a gravity-fed drain.
The float inside the pot contains a small magnet that operates a
reed switch. When the float is in the uppermost position the
switch is held closed. If the sample stops flowing the float drops
slowly, allowing the reed switch to open, providing a sample flow
failure indication.
