this manual introduces the function and usage of viewsonic liquid level sensor
The ViewSonic VS1000-L is a battery-operated ultrasonic liquid level sensor designed to provide instant level indication for chemical tanks or sumps. It uses sound wave technology to measure the distance from the sensor face to the liquid surface, displaying the data on an LCD screen or a remote display via wireless transmission. No wiring is required for the data transmission between the sensor and the display.

No wiring is required as the level data is wirelessly transmitted to the remote display.
Remove the transmitter from the tank, unscrew the four screws from the base, remove the old battery, and replace it with a new 3V CR2450 battery.
The flashing of the LED light and LCD bars indicates a leak has been detected.
When the tank level is below 10% of the usable volume, the display alternates between showing 'Gal' and 'Lo', and an audible alarm sounds every 60 minutes.
