Level Switch

Float-Less Water Level Control

Model FLR-WLAPC

Float-less level alarm and pump control system (FLR-WLAPC) for industrial and marine use, with High/Normal/Low/Low Low sensing, stainless steel electrodes in a cast steel head unit, 5 A relay contacts and sensor cable runs of up to 1000 m.

Overview

About the Float-Less Water Level Control FLR-WLAPC.

The FLR-WLAPC float-less water level control is a level alarm and pump control system assembled specifically for pump control and level control in industrial and marine applications. Instead of a mechanical float, it uses stainless steel electrodes mounted in a cast steel head unit, connected to a plug-in controller that switches the pump and raises level alarms. The controller supports High, Normal, Low and Low Low sensing modes, and the electrode cable can run up to 1000 m from the controller, so the panel can be installed well away from the vessel.

Features

  • No float or moving parts in the vessel: level is sensed by stainless steel 304 electrodes
  • Sensing modes: High, Normal, Low and Low Low
  • Two LEDs show the pump control status
  • Relay contact rating 5 A, 250 VAC (resistive load)
  • Electrode cable length up to 1000 m
  • Mechanical life of 5 million operations minimum, electrical life of 100,000 operations minimum
  • Compact plug-in controller (50 H × 40 W × 58 D) on a PF113A socket
  • Cast steel head unit with DN100 PN40 head flange, rated to 21 kg/cm²

Options

  • Electrode length 500 mm as standard, other lengths on request
  • Optional chamber unit with 275 mm centre-to-centre side flanges (DN40 PN40), other sizes on request

Applications

  • Automatic pump control
  • High and low level alarms
  • Industrial applications
  • Marine applications
