730 Bubbler Module
Section 1 Introduction
1.1 Introduction The 730 Bubbler Module is one of Teledyne Isco’s inter-
changeable modules for the Avalanche and 6700 Series Sam-
plers. The module uses a differential pressure transducer and a
flow of bubbles to measure liquid levels up to ten feet. The
bubbler is unaffected by wind, fluctuations in air or liquid tem-
peratures, turbulence, steam, foam on the surface, corrosive
chemicals, debris, oil, floating grease, or lightning.
You can install the module only on a 6712 or 6700 controller. The
bubble line can be used in nearly any location with a known
level-to-flow relationship.
