Product information

Description

Karlik FWP-3 — industrial/utility level sensor for fluid and tank monitoring is a compact electromechanical level switch for on/off detection of liquid presence and threshold levels. The device is intended for industrial and utility installations where reliable switching is needed for pump control, overflow protection or basic automation tasks. Its simple design supports straightforward mounting and wiring in tanks, sumps or piping systems where a binary level signal is required.

Advantages

The level switch provides reliable mechanical switching with clear on/off output, requiring no complex electronics at the sensing point. Its compact form factor and standard process connection options allow easy integration into existing tanks and control loops. The sensor is designed for robust operation in typical industrial fluids and offers predictable performance for control and safety interlocks.

Suitable for

  • Pump start/stop control in storage tanks and reservoirs
  • Overflow and dry-run protection in utility and industrial systems
  • Simple on/off level alarm or interlock circuits
  • Basins, sumps and small tanks in process and water management applications

Key specifications

  • Sensor type: electromechanical float/level switch for binary (on/off) signalling
  • Application environment: liquids in tanks, sumps and piping systems
  • Output: mechanical switch contact suitable for direct control circuits or relay inputs
  • Mounting: compact housing suitable for standard tank or pipe installation
  • Material and build: industrial-grade components designed for continuous monitoring

How to use

Install the level switch at the required threshold height following the tank manufacturer’s instructions and local wiring regulations. Connect the mechanical switch contacts to the pump starter, alarm input or automation controller according to the control scheme. Verify correct orientation and secure sealing at the mounting point to prevent leakage. After wiring, perform functional tests by raising and lowering the liquid to confirm reliable switching at the set level.

Usage recommendations

For long-lasting, reliable operation, choose a mounting location that avoids excessive turbulence and solids accumulation. Confirm compatibility of the switch materials with the process fluid and ensure electrical connections are protected from moisture. Regular functional checks and occasional cleaning of the sensing area will help maintain dependable level control and prevent false switching.
