Overview
Reservoir operations depend on knowing the water level now, not at the end of a shift. Level is read at the reservoir body and again at the spillway, and pressure is read on the discharge pipeline that carries water away during flood release. These three readings move together when inflow changes.
The measurement points are far apart and some are unpowered. A single sensing method does not fit every point: a radar unit suits a narrow stilling well, an ultrasonic unit suits an open channel, and a pressure transmitter suits the pipeline. Operators wanted one stream instead of three separate records.
Challenges
Points far apart
Level is read at the reservoir body and again at the spillway, and pressure on the discharge pipeline: three places that move together but were recorded apart.
Some points unpowered
Some measurement points have no power and no cable, so each one has to carry its own supply and its own radio.
One method does not fit all
A stilling well, an open channel and a pipeline each need a different sensing method before the readings can be compared.
Solution
Level units sit at the reservoir and the spillway; the pressure transmitter sits on the discharge pipeline. Each one reports through the WES-WIO wireless terminal protocol to the WE-X280 edge gateway, which converges the wireless nodes and any wired device on site.
From the gateway the data goes over 4G or Ethernet to the WES device management platform. Threshold overrun, abnormal change and low battery are checked on the path, and the platform raises SMS and email notices when a level or pressure reading crosses its configured limit.
