1. INTRODUCTION
The ViewSonic Sensor is a battery operated ultrasonic liquid
level sensor that is capable of providing the user with instant
level indication at a glance. The ViewSonic Transmitter uses
ultrasonic (sound wave) technology to measure the distance
from the sensor face to the surface of the liquid in chemical
tank or sump, then back to sensor face; this is referred to as
(time of flight) As the liquid product inside the tank decreases
the distance that the senor measures increases accordingly.
The current level measurement can be viewed directly on the
LCD screen located on the sensor or via the remote display.
No wiring is required as the level data is wirelessly
transmitted to the remote display.
Gallons / Inches / %
After completion of programming the display calculates and
displays the amount of liquid remaining in your tank in
gallons, inches or as a percentage of the tank capacity. In

or metal tank up to 10' (3m) in height, including double

5. TANK SETUP
In order calculate the volume in your tank the ViewSonic Display needs to know the shape of the tank.
There are three (3) basic shapes as illustrated below. Identify the shape that is closest to the shape of the
tank being measured. Each ViewSonic Display is supplied with the default settings as shown. The
ViewSonic Display must then be configured to match the tank’s dimensions that is goingto be measured
