1.2 Probe
The Deltaflow Pitot tube probe assembly consists of an S type Pitot tube, a K type thermocouple, and a
4” mounting flange. All wetted components are constructed of Stainless steel. The Pitot tube comes in
various lengths, and the insertion depth is adjustable for easy installation. Once the desired insertion
depth is determined the Pitot tube is secured in place using a large compression fitting. The impact and
static sample lines are easily terminated on the probe using 3/8” compression fittings. The K type
thermocouple comes in various lengths and has a fixed insertion depth. The thermocouple wires from
the sample line are easily terminate in the head of the thermocouple assembly.

1.3 Sample Line
The Deltaflow sample line consists of a two 3/8” PFA Teflon sample lines, a K type thermocouple
messenger cable, a small amount of insulation, and a PVC jacket. The maximum recommended length
for the standard sample line is 430 feet. Line longer that this will require custom design. Custom sample
lines can be ordered with options such as stainless steel tubes, heaters, larger wires, or extra wires.
