Slanted Nose Section – Under certain conditions - low flow

rates in debris-laden small sewers, for example - the submerged

probe may catch and retain the debris, obstructing the flow

stream and causing erroneous level readings. To avoid this

problem, use the slanted nose section. This nose section has a

slanted leading edge that tends to shed debris more readily than

the standard nose section.

Use the slanted nose section with caution, however, Under condi-

tions of low flow and high velocity, the slanted nose section may

induce a hydraulic “jump” in the flow stream that can cause erro-

neous level readings.

Flume Cap – The flume cap is a small, blunt cap that replaces

the nose section. Most flume manufacturers can supply flumes

with a small cavity to accept an Isco probe. The probe cap pro-

tects the transducer while minimizing the total length

4.3 Mounting Rings The following sections describe sensor installation using the two

options available for mounting the probe in pipes or round-bot-

tomed flow streams. For pipes up to 15" (38.1 cm) in diameter,

stainless steel self-expanding mounting rings (Spring

Rings) are available. For pipes larger than 15" in diameter,

Teledyne Isco offers the Universal Mounting Rings (Scissors

Rings).

4.3.1 Spring Rings To install a spring ring, you compress the ring, slip it inside the

pipe, and then allow it to spring out to contact the inside

diameter of the pipe. The inherent outward spring force of the

ring firmly secures it in place. A typical self-expanding mounting

ring (with a probe mounted on it) is shown in Figure 4-1.

These mounting rings are available for use in pipes with inside

diameters of 6" (15.2 cm), 8" (20.3 cm), 10" (25.4 cm), 12" (30.5

cm), and 15" (38.1 cm). The Teledyne Isco part numbers for the

various size mounting rings available are listed in Appendix B.

These part numbers include not only the ring, but also the mis-

cellaneous hardware necessary to mount the sensor on the ring.

CAUTION

Always wear leather gloves when handling the rings (either

type). The metal is finished, but there is still a possibility of cut-

ting your hands on the edges.
