Customer Pressure Complaint |
|
| One
of the most popular uses for the Telog
Hydrant Pressure Recorders (HPRs) is
to monitor and analyze customer pressure
complaints. The HPR is ideally suited
for this application because it is rugged,
highly portable and can give a complete,
time stamped picture of the pressure
differential between the customer’s
water pressure and the water pressure
being delivered by the local utility. |

Attach
an HPR to the hydrant that is
closest to the customer’s
building and on the same main.
Attach
a second HPR to the customer’s
water line. This can be done
using a garden hose and an HPR
with Telog’s garden hose
adapter. Fill the hose with
water and attach the HPR. Once
the HPR is securely attached,
completely open the customer’s
spigot.

Benefits:
|
•One
person can do it all!
•More accurate and reliable than
chart recorders
•No exposed electronics —
collect data in the rain
•Electronically documented test
results
•Easy to use kits available |
|

 |
Using
Telog’s HPR-31 units for fire
flow testing provides you with more
accurate information than conventional,
manual methods of testing. Because the
HPR is always recording and time stamping
data, the testing can be performed and
completed by one person. The testing
procedure is based on guidelines in
the NFPA 14 and the AWWA M17 manuals,
so you will be sure to meet regulation
requirements. |

|
| Benefits:
|
•One
person can do it all
•Based on NFPA 14 and the AWWA
M17 guidelines
•Moer accurate & reliable
method than pitot gauges
•No exposed electronics —
perform test in the rain |

Add To Your Flushing Program |
|
|
Numerous water
authorities have instituted
flushing programs to help maintain
the health of their distribution
system. In many mains, water moves
through at less than two miles per
hour. Flushing removes built up
sediment that restrict the water.
When you use the Telog Hydrant
Flow System you can simultaneously
accomplish two other important
functions — hydrant capacity
testing and reduce unaccounted for
water. |
|
|
| Benefits:
|
•Hydrant capacity testing
•Capture peak flow rate for color
coding
•Reduce the amount of
unaccounted for water
•One person can it all! |

Calibrating Hydraulic Models |
|
|
Fire flow testing
and C-factor testing are two of
the most common field tests used
for model calibration. Using Telog
HPRs can greatly simplify that
testing (see Telog’s application
notes on fire flow & C-factor
testing) and the data from
Telogers software can be exported
to many of today’s software
modeling packages. |
|
|
| Benefits:
|
Use
exported HPR data in your modeling
software for:
•Model calibration data
•Steady-state analysis
•Extended-period analysis
•Data is stamped with time and date
•More accurate, reliable and flexible
than pitot gauge
|
|
|
|
|
 |
C-factor
testing with HPR units will measure discharge
and head loss. By using HPRs, a task which
normally requires three or more people becomes
a one-person job. There is no need to station
a person at each hydrant. The HPR automatically
records and time stamps the data. This information
can then be used to calculate pipe roughness
in terms of Hazen-Williams C-factor. |
