The Bubbler Liquid Level Controller is used to measure the fluid level in open containers in a simple and accurate way. It is virtually maintenance free and can be used with a variety of liquid temperatures.

Typical liquids include, but are not limited to, the following: water, oils, dilute acids, alkaline solutions, fuels, syrups, inks, paints, alcohols, coolants, solvents, sludge, slurries. Specific applications should be reviewed prior to use.

The Bubbler Liquid Level Controller has a differential pressure controller with two SPDT control relays with adjustable dead bands along with a scalable 4-20mA process output. The Series BLJ provides flexibility in power usage allowing 120/220 VAC or 24 VDC power.

Bubbler Level Controller

Programming is easy using the menu key, with digital display, allowing access to five simplified menus which provide control of:

  • Security level
  • Selection of engineering units (in/ft wc, mm/cm wc, psi, etc.)
  • Set point control or set point and
  • Alarm operation as high/low or high/low alarm
  • Automatic or manual alarm reset
  • Alarm Delay
  • View peak and valley process readings
  • Digital dampening for smoothing erratic process applications
  • Scaling the 4-20mA process output to fit your application’s range
  • Modbus communications available
  • Field calibration

Options

  • Power On/Off selector switch
  • High limit alarm light
  • Low limit alarm light
