The CDI 5100 extends the capability of the CDI 5000 series to the low flow rates found in many point-of-use applications. It does this by concentrating the flow into a small area that is chosen to optimize the tradeoff between pressure drop and low-flow sensitivity. Used in its intended flow range and at a pressure of 100 psig, the 5100 will create a pressure drop no greater than one psi.
User-configurable scaling, filtering and units of measure
Optional wired or wireless output for networking
Like the other 5000-series flowmeters, the 5100 is a thermal mass design, using one probe to sense the air temperature and maintaining the other ten degrees warmer. By concentrating the flow where it passes the two probes, it is able to measure low air flows without requiring small passages that could clog or create excessive pressure drops.
The meter is furnished with a carefully-reamed six-inch piece of 3/8-inch pipe to be installed where the air enters the meter. With this pipe in place, there is no other requirement for flow conditioning or straight upstream pipe. The meter may be installed between quick disconnect fittings to test air usage by small pieces of equipment.
Nominal Pipe Sizes
2 percent of reading plus 0.5 percent of the indicated range at a temperature of 68 degrees Fahrenheit and a pressure of 100 psig.
Compressed Air, Nitrogen
200 psig maximum on Sch. 40 steel and on Type L Copper; consult CDI for other materials and higher pressures.
The CDI 5450 is a modified version of the 5400 model that allows installation under pressure. It incorporates two valves through which the probes pass and a muffler that collects chips from the drilling process. It takes an equal amount of installation time as our standard meters and requires no shutdown of the compressed-air system. View CDI 5450 Installation Video
CDI 25 Point-of-Use Flowmeters
The CDI 25 represents a price-performance breakthrough in compressed-air metering. It fills a need for low-cost measurement of air usage by individual pieces of industrial equipment. It indicates leakage and excessive usage locally with blinking lights, thereby eliminating the need for central monitoring and enabling equipment operators and maintenance mechanics to observe and respond to developing problems.
CDI 6200 for pipes up to 1.5″
Price Range: $525 – $625
Although our initial ruggedized flowmeter is still available for purchase, we now offer the CDI 5000 Series flowmeters with the same great features and the option for wireless monitoring.
The flowmeter clamps onto a pipe, with two flowsensing probes projecting into the pipe through 3/16 in. drilled holes. It seals directly to the pipe; no cutting or welding is required for installation. Because each flowmeter is made and calibrated for a specific size of pipe, the display indicates flow directly, with no setup or adjustment.
CDI 5400 for 2″ – 8″ pipes
Price Range: $675 – $2,305
The CDI 5400 clamps onto a pipe, with two flow-sensing probes projecting into the pipe through 3/16-in. drilled holes. It seals directly to the pipe; no cutting or welding is required for installation. Because each flowmeter is made and calibrated for a specific size of pipe, the digital display indicates flow directly, with no setup or adjustment.
At CDI we take pride in providing the best possible customer service. We accept orders by email, phone, or fax. Small orders received before mid-afternoon for stock products are normally shipped the day they are received.
