Small-Scale Hydroelectric Plant Promises Profit

Small-Scale Hydroelectric Plant Promises Profit

If there’s access to a stream, the only requirements to generate electricity are a 2 ft. drop in water level and two gallons of flow per minute. A hydroelectric system isn’t overly complicated, it isn’t difficult to operate and maintain, it has longevity and it’s often more cost-effective than other forms of renewable power. Some ...

PLC-Based System Works Where Single Loop Temperature Controllers Fell Short

PLC-Based System Works Where Single Loop Temperature Controllers Fell Short

In many applications, single loop temperature controllers are sufficient to provide control of heating and cooling. But in some applications, including the one detailed in this article, closely coordinated control among many temperature control loops is needed. In those cases and others, PLC-based temperature control can be the best solution. A meltblown machine, a melted ... Read More

Upgrading Pump Stations with PLCs

Upgrading Pump Stations with PLCs

When relays and timer circuits get old, they cause problems. Replacing them with PLCs keeps pumps running smoothly. One of the most important jobs of a water distribution system is to reliably deliver water to its customers. At our water district in California, we had pumping stations (Figure 1) with relay-based controls that were more ... Read More
