Logic Beach distributes the CDI line of air flow transducers for use with dry air and nitrogen. These transducers are commonly employed in compressed air systems for long term monitoring as well as during audits to more accurately understand the compressed air supply flow requirements and loading.
The flow meters clamp onto a pipe, with two flow sensing probes projecting into the pipe through 3/16-in. drilled holes (clamp on drill guides are available for installation). The flow meter seals directly to the pipe; no cutting or welding is required for installation. One model, the CDI5450 can be “hot tap” installed on a pressurized compressed air line.
Because each flow meter is made and calibrated for a specific size of pipe, the integral digital display indicates flow directly, with no setup or adjustment required.
The meter measures flow by maintaining one probe warmer than the other. It calculates the gas mass velocity from the amount of heat required, and then calculates the flow on the basis of pipe cross-sectional area. The flow rate, in scfm, is shown on a large, four-digit display. The flow meters come standard with 4-20mA and pulse outputs which directly interface to Logic Beach data logging instruments’ analog and digital inputs. The flow meters can also be provided with a Modbus RTU slave option permitting two wire RS-485 interconnection to Modbus RTU Master enabled data logging and reporting instruments from Logic Beach.
The output signal from the flow meter is simply scaled, totalized, time profiled and reported per the HyperWare program running within the Logic Beach data acquisition, alarming and reporting instrument. In compressed air system applications, the measured air flow coupled with point pressure measurements, compressor run times, electrical power consumption and other measured parameters logged by a Logic Beach data logging instrument, a thorough and accurate compressed air system performance profile can be obtained.
Three models (5100, 5200 and 5400) are available for different ranges of pipe diameters. The 5450 model, a unique variation of the 5400 family, features a special “hot tap” installation capability whereby it can be installed into a pressurized pipe.
Flow Meter Model and Pipe diameter compatibility:
- 5100: 3/8″ ( 0 to 20 SCFM flow rates)
- 5200: ½” to 2” pipe
- 5400: 2” to 6” pipe
- 5450: Same as 5400 but has hot tap installation feature
Drill guides are required for installation of the 5200 and 5400 series and are available from Logic Beach for the various models
