TG-F976-0E APR. 2002 TG-F976-6E SEP . 2013K CDT1000 Series Multi-Digital Flowmeter OUTLINE CDT1000 is a new series of flowmeter which combines a multi- digital indicator with a pitot tube. CDT1000 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 20mm to 450mm 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 35mm dia. hole and welding 20mm (3/4") 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 (2-wire 4 to 20mA) and Alarm Output type ❏ Indicator parts are interchangeable. ❏ Easy to see because of large LCD display ❏ Compact size and lightweight ❏ Quick delivery STANDARD SPECIFICATION

CDT1000 QUICK FLOW for Air Conditioning Application Digtal Flowmeter TG-F976-6E6 INSTALLATION 1) Keep the upstream and downstream straight runs as required. 2) To install the flowmeters, Drill a hole of 35mm diameter into the pipe having more than or equal to 40mm diameter. Use the three-way socket for the pipe having less than or equal to 32 mm diameter. 3) Select and drill the hole at right place so that the final fixed pos- ture 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 CDT1000 into the welded socket to complete the installation.

• The model CDT 12(4) 10 flowmeter is calibrated based on the inside diameter of JIS G3452 SGP . For the model CDT 12(4) 20, calibrated JIS G3454 Sch.40. 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 /H1101732mm /H1108410D /H110845D /H1108440mm /H110845D /H110843D Note) D : Inside diameter of main pipe.
• Run the fluid fully in the pipe. Otherwise it could not be measured.
• Vent the air before measurement. See CDT1000 Instruction Manual for further details. LINING AND OTHER PIPING
• The full scale flow rates are based on when the flow runs through the inside diameter of the pipe lined with PVC which consists of a tee joint of the Eslo coat LX made by Sekisui Chemical Co.’s Eslon®. If you use the tee joints with the different inside diameter from above, the extra calibration is required. For further consultation inform us of the dimension “D” in the following drawing.
• When the main pipe size is between 32 mm and 150 mm, provide either one of the following tee joint and bushing assembly to make the connection size 20 mm: — tee joint with 25 mm in branch line + A bushing with 25 mm x 20 mm — tee joint with larger than 25 mm in branch line + One or more bushings in series to make the final connection size 20 mm For further consultation inform us of the dimension “L” in the following drawing.
• Piping can be customized.
• Please determine the values of “D” and “L” in the figure below and the kind of pipe and then contact us.
