Pressurized Line Accessory

For Teledyne ISCO 6712, Avalanche, and 5800

Pressurized Line AccessoryThis accessory was developed to allow sampling from liquid sources with pressure ratings between 10 and 300 psi. Initially, a stainless steel pressure reduction valve decreases source pressure to an acceptable level (10 psi). 

Special software (required as an option for 6712 and Avalanche samplers), activates an electric ball valve – via the valve interface – directing liquid to the collection bottle during forward pumping. The ball valve also allows any liquid remaining in the section of line between the ball valve and the sampler to be purged prior to the next sample being drawn. 

Note: Photo shows purge line lower than desired. Optimum purging occurs when sampler outlet is higher than connection to valve.
