CDI 5400 Compressed Air Flow Meter

Quick Overview

The CDI 5400 series of compressed air flow meter are suitable for larger pipe diameters from 2" up to 8". The flow meters provide a local display of compressed air flows with 4-20mA and pulse outputs, plus the option of Modbus RTU outputs. The CDI 5400 flow meter clamps onto the pipe using a single mounting ring that contains both flow-sensing probe projecting into the pipe through 3/16-in. drilled holes. The meter seals directly to the pipe and therefore required no cutting or welding for installation. Each flow meter is made and calibrated for the specific size of pipe and does not require any setup or adjustment.

Details

The CDI 5400 is similar to the CDI 5200, except that it has its probes mounted side-by-side in a single ring, its display can rotate to accommodate pipe orientation, and it is built for larger pipe diameters. Like the 5200, it is a thermal mass flow meter in which one probe senses the air temperature and the other is maintained ten degrees above the air temperature. It has the same milliamp and pulse outputs, the same large, bright display, and optional wired and wireless outputs. The new wireless output makes central monitoring practical where it might not otherwise be considered.

The CDI 5400 is commonly used for monitoring of compressor-room output and distribution lines in medium to large-sized facilities. It is also used for point-of-use monitoring in industrial processes that use large amounts of compressed air.

Pressure Sensing Option

The pressure-sensing (-PSO) option for the CDI 5200 flow meter allows plant managers to monitor pressure throughout an air distribution system along with flow. The pressure sensor is mounted next to the flow-sensing probes. It accesses pipe pressure through a cutout in the gasket that seals the ring to the pipe and there are no additional steps during installation. The pressure signal is provided as a second milliamp output. With this option, both milliamp outputs are non-isolated; they source current to be returned to the meter’s dc-connection. The display can be configured to show the pressure signal, and the pressure signal is also available through the optional wired and wireless serial outputs.
