The Level Master™ is a water driven chemical proportioner that will automatically maintain a constant supply of ready-to-use solution. When the solution in the container drops below a pre-set level, this venturi injection system uses city water pressure (25 - 80 PSI) to draw and blend chemical concentrate into the water stream to create an accurately diluted solution using precision metering tips. The solution replenishes at 2.4 GPM @ 40 PSI and will cycle continuously.
