PRELIMINARY

The TankScan Wireless Level System WL2 Monitor consists of an
electronics housing and a "waveguide" probe for measuring tank fluid level.

System Installation Steps

A. Install controller (distance & line-of-sight location predetermined).
B. Install monitor(s) on the tank(s)
C. Install fill indicator(s) at a accessible location near the fill point.
D. Install software on host PC
E. Power up and configure the controller
F. Power up the monitor(s) and fill unit(s).

Monitor Installation

Precautions

A. Ensure the bottom of the probe (weight) does not rest

on the bottom of the tank, because the waveguide wire
may become slack — resulting in measurement errors.

B. Ensure the probe waveguide wire does not

touch anything inside the tank (e.g., riser) —
if it does, it could cause false readings.

C. DO NOT install the monitor in a riser unless it has a

blank length (optional non-active coax probe exten­sion) greater than the riser height.

1. Unpack Monitor assembly (carefully un-wind the probe's waveguide wire/
weight), then carefully hand-straighten the wire — making sure not to kink
or damage the wire.

2. Install Monitor — screw bottom of monitor into a 1-1/2 or 2 inch female
NPT connection — hand tighten only.

3. After installing and configuring the TankScan Controller, install Monitor's
Battery Pack (included). Remove the Monitor's compartment cover by
unscrewing the (2) screws (w/small bladed
screwdriver). Insert battery pack into compart­ment and plug keyed connector into the socket
(on right). Finally, position the wires to prevent
damage, then reattach the cover.
