Level Master™ (Single Float - No Tank)

Model # 989303

The Level Masterâ„¢ (Single Float) is a water driven chemical proportioner that automatically maintains a constant supply of ready-to-use solution in a paired tank (sold separately). When the solution in the tank 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 cycles continuously.

Key Features
  • Automatically maintains a pre-set level of ready-to-use chemical solution in a paired tank (sold separately, see options)
  • Unsinkable solid polypropylene float suspended by a rigid "push rod" ensures smooth operation and prevents the float valve from sticking in the open position
  • Chemical resistant wetted components ensure years of outstanding performance with minimal maintenance
  • Downstream check valve prevents back-flow of liquid or vapor into the float valve to eliminate the potential for damage to internal components
  • Industrial-strength design holds up in tough environments
  • Paired tanks are available in several sizes and include a rigid suction tube and hose barb(s) to facilitate dispensing
  • Available with a secondary fail-safe float (#989304)
