Float and guided-wave radar for pulp levels in flotation cells
Flotation PulpMaster (FPM) controls liquid (pulp) levels in flotation cells with a compact, low-profile HDPE float designed to resist buildup, combined with an encapsulated sensing element that protects it from harsh environments. The system targets millimeter-level measurement performance (±3 mm accuracy, 1.0 mm resolution), while responding directly to pulp levels rather than froths.
FPM’s is based on proven, field-evaluated, pulse guided-wave radar, float-level technology, which is engineered to deliver stable, pulp-level signals in turbulent, aerated slurry environments. The unit is specified for three measurements per second, supporting tight process control when valves are actively modulating.
FPM integrates flotation-specific hardware, including built-in water-jet cleaning and a clamp-on, 6-in., ANSI, multi-fit flange with cleaner spray assembly. It measures the pulp interface up to 1 m below the launder, with a minimum blanking distance of 150 mm or less.
Other features includes:
- Only one moving part
- Air purge and water spray ready
- Pulse radar for bubble-column level tracking
- Stainless-steel and PVDF construction
- Handrail or floor-grate mounting ready
FPM is also available with multiple output options, including analogue 4-20 mA, HART 7, Modbus (four-wire), Modbus TCP/IP and Poer over Ethernet (PoE), which makes it ready for straightforward integration into flotation cells.
