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.

Typical Installations

Installations will vary in many cases. Actual locations of sample collection sites must be confirmed by the permitting agency.
