21.1 Introduction to the H-355
The XL™ has special functions for operation with the W
ATER LOG Model H-355 gas purge ®
system. The W ATER LOG Series Model H-355 (hereafter "H-355") is a self-contained "SMART ®
GAS" purge system used to measure fluid levels in applications such as surface water (streams
and lakes, etc.), ground water, and tanks. It contains a small holding tank and a compressor, and
is designed to replace the Nitrogen tank and regulators used in traditional gas purge systems.
When combined, the XL™ and H-355 communicate back and forth via the RS-485 link. The
XL™ has a submenu dedicated to changing the configuration of the H-355.
21.2 H-355 Menus
The following is a description of the submenu used for configuring the H-355. Each of these
