Level Measurement

When accurate and reliable level measurement is required, the DCC Level Measurement product line offers a wide variety of solutions to meet your application requirements.

Products include:


Bubbler Level Measurement Systems

DCC bubbler level measurement systems are recommended for measuring levels of sewage, drainage water, or water with large quantities of suspended solids.  They are typically used in applications where foam, solid debris, sewage sludge, or turbulence make ultrasonic, microwave, or float switch devices ineffective.  The DCC bubbler level measurement system has no electrical components at the point of measurement which makes them less susceptible to lightning when compared to other types of submersible level sensors.  The only part of the system that contacts the liquid is a bubbler probe tube which can be located away from the rest of the system.

Bubbler Level Monitors

The Bubbler level Monitor (BLM) is an automatic bubbler type level measurement and display unit that periodically samples the level of most liquids.  It operates by forcing compressed air into a bubbler tube with its opening placed near the bottom of the liquid. The BLM measures the pressure required to force air through the tube and generates a 4-20 mA signal which is proportional to the depth of the liquid in addition to displaying the sampled level.

Bubbler Level Transmitters

The Bubbler Level Transmitter (BLT) is an automatic bubbler type liquid level measurement system. The bubbler level transmitter operates by forcing compressed air into a bubbler tube at a constant rate with its opening placed near the bottom of the liquid. The bubbler level transmitter measures the pressure required to force air through the tube and generates a 4-20 mA signal which is proportional to the depth of the liquid.

Bubbler Pump Controller Level Transmitters

The Bubbler Pump Controller (BPC) Level Transmitter is a user-configurable control and display unit which automatically controls a bubbler type level measurement system.  It operates by controlling up to two air compressors that supply air on demand into a reservoir tank to maintain a minimum pressure via user setpoint inputs. This pressure forces air at a constant rate into a bubbler tube with its opening placed near the bottom of the liquid. The pressure required to force air through the tube is proportional to the depth of the liquid.

Features include:

  • Built-in bubbler level measurement control system with internal pressure transducers that operates up to 2 air compressors.
  • Range up to 20 feet standard.  Other ranges available.
  • Automatic purging to keep bubbler line clear.
  • Manual bubbler line purge request input.
  • Automatic air tank moisture drain valve control.
  • On, Off, High, and Low setpoints adjustable from front panel or remotely via serial port.
  • 40 segment bargraph displays level, setpoints, air tank pressure, and air flow rate through the bubbler line.
  • External digital level display available.
  • Air compressors and alarms status indicators on front panel.
  • Front panel test knob for simulated level input testing.
  • 4-20 mA signal output proportional to level.
  • Various specific gravities available to accurately measure most liquids.
  • RS-232 serial port for SCADA communications support and PC interfacing.
  • Uses non-volatile memory allowing system to retain program software and setpoints during power loss.
