The Liquidator uses a vertical guide tube. The indicator slides up and down on the outside of the tube while the counterweight is contained in it. As the polyethylene float is the only part in contact with the liquid, the Liquidator is suitable for most chemical tanks as well as water tanks.
As the polyethylene float is the only part in contact with the liquid, the Liquidator is compatible with a wide range of liquids: sodium silicate, waste oil, waste water, effluent, molasses, wine, olive oil, hydrochloric acid, phosphoric acid, etc.. Liquidator liquid level indicators are often used on fertilizer storage tanks, also swimming pool hypo and backwash tanks.
Just a simple, mechanical float/weight/pulley system - no gimmicks, no batteries. True reading too – unlike home-made gauges that read back to front, these gauges show true water level. The weighted float and indicator are connected to the counterweight 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.
Please note that these level gauges fit tanks as tall as 10ft high. If you have a taller tank, please call to allow us to place a custom order for you.
