The Rollie Systems Wireless Tank Gauge consists of either a multi-tank or single tank controller and 1 or more ultrasonic sensors.
Our standard sensor is constructed of mainly ABS plastic and nickel plated steel. It is a low cost solution for non aggressive
media such as waste motor and cooking oil, diesel fuel and home heating oil.
In the case of both single and multi-tank systems the controller needs WiFi in order to send data to a server. If
your router is too far away from the controller consider a WiFi extender system such as TP-Link or Netgear.
Once a WiFi link has been established the controller will send level, volume and alert status to our server every 30 minutes. (Please refer to the Internet Page for more information on how that part works).
Low oil alerts can be sent from the server to any 10 digit cell phone number and / or email address.
Refer to the drawing for dimensions. Be sure to leave enough height above your tank in order to install it. The standard gauge can measure tanks up to 12 feet tall. Alternative models are available and can reach heights of 50 feet.
