An Inside Look at the Reverse Float Level Gauge
Knowing the liquid level in a chemical storage tank is important for a number of reasons. You have to know when to order more chemical, and certain chemicals have to be stored at a specific level to maintain their properties and/or operational requirements. A reverse float level gauge is helpful in that it lets you know, from the outside of the system, how much chemical is in your tank.
Why Design a Level Gauge
A level gauge of any kind monitors the liquid level of what is being stored in the polyethylene tank. There are several types of gauges including clear tube level gauges, ultrasonic level gauges, etc. While it works with many types of level indication, in almost all cases we recommend our reverse float gauge for use with chemical storage tanks.
How a Reverse Float Level Gauge Works
Perhaps counterintuitive at first glance, this simple level system contains a float inside the tank and a visual indicator on the outside. As the tank is filled, the chemical lifts the float which in turn allows the weighted indicator on the outside to move down. This is done using a pulley system with polypropylene rope and PVC rollers inside of PVC elbows. As the tank empties, the float inside the tank drops pulling the indicator up. This is why it is called a reverse float level gauge.
