Storm Water Samplers |
|
Simple Low Cost Sampler for
Storm Water Run-off |
|

_ |
The primary design of this product is to
capture grab samples and/or composite (time weighted, continuous
collection) samples.
The Sampler comes in two sizes, 0.80 gallon and 5.50 gallon capacities.
Both have an adjusting screw at the top of the ball valve for controlling
the rate at which the liquid enters the Sampler. As the adjusting screw is
turned downward the ball is restricted in its vertical lift and throttles
the orifice opening. When the adjusting screw is adjusted down against the
ball, the valve is held closed. For example, when the adjusting screw is
opened (1/2) one half turn it will take clean water approximately 20
minutes (.80 gallon capacity, 1.0 inch head) to fill and shut off. When
the adjusting screw is fully open (approximately 10 turns) the Sampler
will fill in approximately 2 minutes. The adjusting screw is a precision
machined screw with slight resistance so as not to slip from its selected
position. Because the effluent is site specific some experimenting will be
required to obtain the desired setting.
