CDT3000 SeriesMulti-Digital Calorie Monitor

OUTLINEThe CDT3000 calorie monitor consists of a pitot tube type flowelement with a built-in temperature sensor and a differential pres-sure instrument equipped with root extraction and calorie calculationfunctions. By inputting an external temperature signal and calculat-ing temperature difference, it indicates and outputs thermal flow andtotalized calorie in addition to flow rate. Applicable pipe size rangesfrom 20 mm to 450 mm.

FEATURES Easy installation by welding a 20 mm, 3/4 inch socket on exist

ing piping for insertion of CDT3000 Simultaneous measurement of both flow and temperature saves

your installation cost Negligible small pressure loss Selectable from wide variety of flow meter ranges suitable for

your applications Applicable for both horizontal and vertical pipes By inputting temperature signal on the fluid feed line it allows

thermal flow measurement and totalized calorie calculation toserve as a calorie monitor for your energy conservation

Easy to read with a large LCD display

*2 Select a proper flow range so that normal flow rate becomesbetween 50% and 100% of the full scale range especially at thetotalized flow and pulse output-emphasized measurement. Theaccuracy of flow rate measurement is ±5% of full scale. Accord-ingly in the totalized flow measurement, if the normal flow rate israther low compared to flow range, the accumulated error re-sults in higher.

Note 5: Above full scale ranges are based on the flow rate when theflow runs through the inside diameter of the pipe lined withPVC. The pipe consists of a tee joint of the Eslo coat LXmade by Sekisui Chemical Co.Åfs Eslon(R). Its maximumoperating pressure is 1 MPa. If you use the tee joints withthe different inside diameter from above, the extra calibra-tion is required.If your size is different from the one in the standard dimen-sions of D and L of PVC lining pipe described on page 7,consult us.

Option code : PL for 32 to 150 mm

The full scale ranges are based on the flow rate when the flowruns through the inside diameter of the pipe lined with PVC. Thepipe consists of a tee joint of the Eslo coat LX made by SekisuiChemical Co.’s Eslon®.If you use the tee joints with the different inside diameter fromabove, the extra calibration is required.For further consultation inform us of the dimension “D” in thefollowing drawing.

When the main pipe size is between 32 mm and 150 mm, provideeither one of the following tee joint and bushing assembly tomake the connection size 20 mm:— tee joint with 25 mm in branch line + A bushing with 25 mm x20 mm— tee joint with larger than 25 mm in branch line + One or morebushings in series to make the final connection size 20 mmFor further consultation inform us of the dimension “L” in thefollowing drawing.

Without these dimensions Tokyo Keiso Co., Ltd makesthem comply with our standard practice as shown in the followingtable. The full scale flow rate will be set as the values in the tableon page 2.

Consult Tokyo Keiso Co., Ltd. for the additional equipment suchas the feed line temperature sensor (RTD) and protection well forits installation or else.

STANDARD ACCESSORY Protection cover for indicator

Avoid installing this instrument at the places exposed to directsunlight or rain as much as possible. If it is inevitable, providewith a protection cover above indicator.

OTHER PIPES Other types of piping configuration are also available. Feel free to contact Tokyo Keiso Co., Ltd. Inform us your piping

specifications and following L and D dimensions.

from 20 to 32 mm as shown in the following drawing.Weld a socket on the straight pipe and install the flowmeter onthe socket for the pipe sizes 40 mm or more.You can install the flowmeter either on horizontal or vertical pipefor model CDT32.

FLOW MEASUREMENT CONFIGURATION

Install the CDT3000 on return line. The CDT3000 installed on feed line gives a calculation error and results in wrong measurement.

PARAMETER SETTING AND ADJUSTMENT

The key operation on the front panel enables the setting changes.• Mode change : Selectable from “Automatic change-over cooling or heating”, “Cooling fixed mode”, “Heating fixed mode”• Low cut-off of flow rate : Can be set at any value between 0 to 100% F.S. (Standard setting : 7%)• Indication filter : Selectable from 0, 2, 4, 8, 16, 32 seconds in moving average. Applicable for flow rate/thermal flow, feed

and return temperature.(Standard setting : 4 seconds for flow rate/thermal flow, 4 seconds for feed and return temperature)

• Maximum temperature difference : Can be set at any value between 0.5 to 80.0°C. (Standard setting : 20°C)• Zero adjustment : Available for flow rate/differential pressure, temperature difference.

The thermal flow is determined by the following equation.Thermal flow F = Q TS—TR k = Q T k [MJ/h]

Flow rate : Q [m3/h] : Measured by CDT3000Feed line temperature : TS [°C] : Measured by a RTD supplied by customersReturn line temperature : TR [°C] : Measured by CDT3000Calorie conversion coefficient : k [MJ/°Cm3] : At cooling mode 4.186/ At heating mode 4.123

Note : When T 0.5°C, the thermal flow automatically becomes 0 MJ/h due to the low cut-off function of temperature difference.

*6 Operation at 25°C or lower is cooling mode, and 30°C or higher is heating mode according to our standard practice. The different specifiedvalues override these values. At start up just after the installation of CDT3000 when feed line temperature is between 25 to 30°C, the thermal flow is calculated and indicated as k= 4.186 MJ/°Cm3.Even at this stage, when T0.5°C, the thermal flow becomes 0 MJ/h due to the low cut-off function.



INITIAL PARAMETER SETTING CODE (Please specify also MODEL CODE on page 5)

*7 Setting of Temperature at cooling and heating mode, Current output required or not, Pulse output required or not, No alarm output designation, Back light required or not can not be set by the indication key operation. However, if current output or pulse output is added, the output items can be also changed by indication key operation.*8 Align the flowmeter in the same flow direction as indicated. The change of flow direction after start-up requires the stoppage of liquid flow.*9 Designate the values of full scale range and maximum thermal flow if other than standard ranges are required , referring to the "INDICATION SETTING LIST" while selecting code "Z".*10 If you have any other special setting requirements other than above, feel free to contact us
