CDT1000 Series QUICK FLOW. Digital Flowmeter for Air Conditioning Application OUTLINE FEATURES STANDARD SPECIFICATION

Transcription

1 QUICK FLOW CDT1 Series Digital Flowmeter for Air Conditioning Application OUTLINE CDT1 is a new series of flowmeter which combines a multidigital indicator with a pitot tube. CDT1 detects the differential pressure exerted by flow velocity in the pitot tube inserted in the pipe and outputs flow rate with digital indication. Applicable sizes range from 2mm to 4mm dia. The principal applications are for hot and cooling water lines for air conditioning in apartment and office buildings and other facilities. FEATURES Easy installation Installation simply by making a 5mm dia. hole and welding 2mm (/4") socket at measuring point of existing pipes. This is most convenient for renewal use when additional flow sensor is required on the line. Low pressure drop Wide measuring range Measuring range selectable depending on application Applicable for both horizontal and vertical pipes. Various indicator functions selectable from the following: Battery type, Current Output type (2wire 4 to 2mA), Alarm Output type, and LonWorks type Indicator parts are interchangeable. Easy to see because of large LCD display Compact size and lightweight Quick delivery STANDARD SPECIFICATION Measuring Fluid : Water, Cold water, Hot water Max. Pressure : 2MPa Max.

6 CDT1 QUICK FLOW for Air Conditioning Application Digtal Flowmeter INSTALLATION 1) Keep the upstream and downstream straight runs as required. 2) To install the flowmeters, Drill a hole of 5mm diameter into the pipe having more than or equal to 4mm diameter. Use the threeway socket for the pipe having less than or equal to 2 mm diameter. ) Select and drill the hole at right place so that the final fixed posture of indicator should be horizontal. 4) Weld the socket to the drilled hole. The centerline of the socket must be in line with the one of the pipe. 5) Screw the CDT1 into the welded socket to complete the installation. SUGGESTIONS The model CDT 12(4) 1 flowmeter is calibrated based on the inside diameter of JIS G452 SGP. For the model CDT 12(4) 2, calibrated JIS G454 Sch.4. Consult TOKYO KEISO if pipes are different from above. Specific calibration is required. Straight length for upstream and downstream is required for accurate measurement as shown in the following table, Size Upstream Downstream 2mm 1D 5D 4mm 5D D Note) D : Inside diameter of main pipe. Piping CDT12 CDT14 Threeway socket (2 to 2mm) Threeway socket Rc/4 Rc/4 Threeway socket Run the fluid fully in the pipe. Otherwise it could not be measured. Vent the air before measurement. See CDT1 Instruction Manual for further details. LINING AND OTHER PIPING In case of PVC lining piping, prepare bushing (25mm x 2mm) for the main pipe in more than 2mm and for branch tube in 25mm.
