Sci-tech Rainfall Simulator Model FM 47 for Education

Features

• Ability to take many measurements quickly without having to wait for natural rain.
• Ability to work with constant controlled rain, thereby eliminating the erratic and unpredictable variability of natural rain
• ‘Sci-Cal’ Data Acquisition System as an optional accessory.

Sci-tech Rainfall Simulator Model FM 47 consists of a metal stand which is used to support spray head assembly which consists of Water sprinklers. The unit is used with its accessory tray for laboratory experiments which is enclosed with Sight Glass. In use, water is pumped from the holding tank through control valve& flow meter to the Water sprinklers. The Water circulating pump is used to feed the water into the nozzle assembly through the pipe. For use in laboratory electrical and water supplies are required.

LIST OF EXPERIMENTS

• The relative protection afforded by different plant densities
• Studies of relative Soil Erosion
• Studies of soil infiltration characteristics
• Erosion and runoff from up and down slope row crops.

SYSTEM SPECIFICATIONS
