Profile: CDI Meters, Inc. focuses on compressed-air metering. We provide CDI 5200 & CDI 5400 flow meter series. Our accessories include summing and averaging remote displays, data loggers, and flow nozzles to verify flow meter performance in place. Our flow meters represent a radical departure from conventional designs, providing accurate placement of the probes within the air stream. The meter clamps around the pipe with its probes projecting through drilled holes. The meters make them ideal for installation throughout an air distribution system.
