Sensor Installation and Connection 5-53
3. Pull the ties until they are taut.
Warning: Do not over-tighten the cable ties or kink the
sensor cables! The depth cable sheathes two components:
the electrical cables that operate the sensor and an air tube
that ventilates the sensor (when applicable). Over-
tightening the ties or kinking the cable can damage or
restrict the air tube, causing incorrect pressure depth
readings. In addition, make sure the connector-end of the
sensor is not kinked, does not contain moisture, and
includes an attached dryer tube filled with active blue
desiccant.
4. Use the diagonal cutters to cut off the excess portion of the
cable ties.
Mounting the ParaDepth, ParaFlow, Surface
Combo Sensor or Ultrasonic Depth Sensor
Three (3) special installation methods are available for mounting
the ParaDepth and ParaFlow sensors. Two (2) special installation
methods are available for mounting the Ultrasonic Depth sensor
and one (1) for the Surface Combo Sensor:
z Standard Mount This mount is used for mounting the
ParaDepth, ParaFlow, Surface Combo or Ultrasonic Depth
sensor in the pipe during special installations.
z Surcharge Mount This mount primarily is used for
mounting the Ultrasonic Depth sensor in the manhole at sites
where the flow continually occurs within 2 inches (51 mm) of
the top of the pipe, pipe conditions and/or hydraulics prohibit
the installation of a sensor in the pipe, or surcharges frequently
occur. Surcharges are conditions where the flow completely
fills the pipe and extends up into the manhole. See Installing
the Sensors in the Manhole Structure on page 5-80.
z Topside Retrieval System This mount supports the
installation of the ParaDepth or ParaFlow sensor in the
manhole structure and allows for easy retrieval of the sensor
for maintenance purposes without descending the manhole. See
Installing the Sensors in the Manhole Structure on page 5-59.
