Wind energy is one of the fastest-growing forms of electricity generation in the world. U.S. wind power market share is expected to reach 8.4% by 2021. More optimistic industry experts predict that wind energy will meet 20% of the nation’s energy needs by 2030. As supply and demand for wind power grows, so will the need to increase the efficiency of wind turbines, to drive costs out of the process and deliver cost-effective renewable energy solutions.
WIND TURBINE OIL RESERVOIR:As wind energy technology advances, higher demands are placed on turbine lubrication systems. Lubricant reservoirs of up to 550 gallons (2,000+ liters) serve as oil storage in centralized systems to provide lubrication for the blade bearings, blade tilt, main bearing, azimuth bearing, meshing gears, generator bearings, cylindrical gears, bevel gears, rolling and sliding bearings, worm gear units, and gear couplings. The oil reservoir is monitored using continuous or point level.
Recommended Continuous Level Technologies:Guided Wave Radar, Ultrasoni
Recommended Point Level Technologies:Float Actuated, Ultrasonic
WIND TURBINE GEARBOX:Gearbox and bearing lubrication are of particular importance due to the complexity of the gearbox and the high mechanical loads. Gearbox and bearing problems are a common cause of downtime, and loss of oil through a small leak has led to catastrophic wind turbine failures. Along with vibration, temperature, and flow sensors, a low level gearbox oil alarm is a critical safety control.

Water Pumping Level Application
WATER PUMPING STORAGE:For industrial and agricultural use, a water pumping windmill is typically placed above a well or near a river. Next to the mill a storage tank is placed to provide a buffer supply of water for when the mill is not operational. Ferro-cement and steel tanks are typically used.
