DDCC - Model DC (BLT)- 12138-P - Bubbler Level Transmitter- Brochure

The Plant Air Bubbler I,evel Transmitter (BIT) model 12138-P is an automatic bubbler type level measurement system. It operates by forcing existing plant air into a bubbler air tube at a constant rate 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. The BIT measures this pressure and generates a 4-20 mA signal which represents the depth. The unit includes a built-in purging cycle to keep the bubbler line clear from obstructions. The BLT also includes an KS-232 serial communications interface designed to support SCADA systems using a variety of Modbus based communication devices giving the system remote data acquisition, monitoring, and control capability.
