Connecting probes into a pipe

All Atlas Scientiﬁc probes can be connected into a pipe.

(This is known as “mounting the probe inline”).

Max flow rate = none

There is no maximum ﬂow rate. These probes can take accurate readings at any ﬂow rate.

(Extreme ﬂow rates will damage the probe. If the ﬂow rate is strong enough to break your

ﬁnger it will break the probe too).

Minimum flow rate = Only the Dissolved Oxygen probe needs moving water. In stagnant water, the readings will read lower than normal. The minimum flow rate for Dissolved Oxygen can not be easily quantified. The slightest movement will correct the problem. All other probes can take accurate readings in stagnant water.

The problem with mounting a probe upside down has nothing to do with the probe itself; and everything to do with with the flow of water. Common problem I Water trap Gravity Gravity Water flow Trap Water will collect in a trap. This water will move much slower than the rest of the water in the pipe. Your readings will seem to move slowly or become stuck. It will appear that the readings are flow rate depended (which they are not) because increasing the flow can get the readings to normalize.

Common problem II Debris trap Gravity Gravity Trap It is with 100% certainty that debris will collect in the trap. Depending on what the probe is used for that debris could be undissolved chemicals, sand, mud; you name it. Whatever it is, it is guaranteed to affect your readings. Probe drying Some probes (like pH) can not be stored dry. A common concern is that if the probe is mounted vertically and the water flow stops the probe will dry out.
PAGE 5
Closed system In a closed system the probes will never have an opportunity to dry out. The humidity in the pipes will be around 100% even if no water is flowing. Open system In an open system the probes can dry out. You will need to engineer a solution to this problem.

Mounting probes into a vertical pipe Mounting probes into a vertical pipe is simple; you don't have to worry about water or debris getting caught in the trap.
