RIVERINA POLY

Australia's most popular water tank gauge.

How IT Works

Just a simple mechanical float/weight/pulley system - no gimmicks,

no batteries. True reading too –unlike home-made gauges that read back to front, this gauge show true water level.

 

The weighted float and indicator are connected to the counter-weight by separate cords, each cord running over a pair of pulleys.

 

When the float is half-immersed everything is balanced.

 

Rising liquid level lifts the float up, the counterweight moves down, and the indicator keeps pace with the float. Falling liquid level causes the weighted float to pull the counter-weight up, and again, the indicator keeps pace with the float. At all times the indicator matches the liquid level exactly.
