2.4 conclusion
According to lengths and pressure-wave speeds of pipes in present research (Field
Tests), it seems that it is necessary an advanced optimization algorithm. Algorithm
considers lengths and pressure-wave speeds of pipes that must be installed at Rasht
Water Transmission Line. Research suggests that advanced flow and pressure sensors
with high-speed data loggers must be installed in Rasht Water Transmission Line.
Data loggers must be linked to “PLC” in water pipeline. It will be recorded Pulsation
and fast transients, down to 5 milliseconds for water flows interpenetration. Pressure
transient recorder is a specialized data logger for monitoring rapid pressure changes in
water pipe systems (i.e. Water Hammer) which is better to supplied in portable mode.
Pressure Transient Loggers must be completely waterproof, submersible and battery
powered .It must be maintenance free for at least five years. Pressure transient spikes
are major cause of bursts and the associated expense of repair, water lost and inter-
ruptions to supply. Conventional loggers do not log rapidly enough to identify these
transients which often last only seconds. For applications in Rasht Water Transmis-
sion Line Monitoring, MultiLog GPRSTM is ideal for monitoring flow and pressure.
For water quality parameters monitoring to assess demand, leakage and conformance,
MultiLog GPRSTM, can be used as well. For Network Analysis Investigations Mul-
tiLog GPRSTM can be used to perform dynamic flow and pressure analysis for Rasht
Water Transmission Line models, particularly where hourly data updates can be useful
for near real time monitoring.
