Page 3: Design And Application Conditions
I. DESIGN AND APPLICATION CONDITIONS Design CPT-01 Turbine Quantometers are instruments used for measurement of gas volume that flows through an installation. Standard version allows to be installed where explosion hazard zones may occur (air and gas mixtures - class IIA and class IIB; with special version – also class IIC).

II. CONSTRUCTION AND OPERATION The turbine quantometer operation is based on the proportionality of the rotational speed of the turbine wheel to the linear velocity thus to the flowing gas volume. Gas entering the meter (Fig. 2) is directed through the inlet flow straightener into the measurement assem- bly and causes the rotation of the turbine wheel.
Page 7 2. Measurement assembly. It consists of the turbine wheel, the turbine wheel housing, the measurement assembly housing, shafts and gears. The turbine wheel is placed in the axis of the quantometer body and is provided with high precision bearings. The standard version uses bearings with a supply of grease.
Page 8: Index And Measurement Ouptuts
III. INDEX AND MEASUREMENT OUTPUTS The reading assemblies of the CPT-01 Quantometer consist of a mechanical index with incorporated electric signal outputs, a pressure tap and a tap for installation of an external HF pulse transmitter (from the turbine wheel). These outputs enable the control of the instrument operation and connections of external devices.
Page 9 and covered by a protective cap. The mechanical output (Fig. 3a) may be used to drive exter- nal devices. The rotational speed of the shaft is identical to the speed of the fastest counter drum. The shaft rotates in a clockwise direction. Maximum allowable momentum on the out- put shaft tip is 0.25 Nmm (Fig.

Page 14 Temperature measurement outputs. CPT-01 quantometers are equipped with temperature measurement outputs only when delivered as a special order version; temperature sockets are not available in standard ver- sions. Temperature measurement outputs are located on both sides of the main body of the meter (Fig.
Page 15: Marking And Calibration Of Quantometers
IV. MARKING AND CALIBRATION OF THE QUANTOMETERS Basic specification of the gas meter, serial number and production year is shown in the nameplates (Fig. 8 and Fig. 9). The plates are fixed to the index housing by means of screws. Two first digits of the serial number indicate the gas meter size code, according to Table 2.

Information marks Each quantometer is calibrated in the manufacturer’s laboratory or other recognized laboratory. The calibration certificate may be delivered on customer’s request. Connections that are not being dismantled during the quantometer installation are protected with seals of the manufacturer or of a recognized laboratory (P1, P2, P3, P4, P6 and P8 Fig.

Location of seals on the CPT-01 Quantometers (new version) Protective seals installed on the pressure sensor tapping (P5), on the temperature outputs (P9), on the HF transmitter (P7) and optional on the mechanical output (P10) are marked by the manufacturer, by the gas supplier or by the authorized installer.

Page 27 The quantometer should be installed in piping of the appropriate nominal diameter. Proper alignment of the meter and pipe flanges should be assured. It is recommended to install ap- propriate upstream and downstream pipe sections. Turbine quantometer in standard version (Fig. 12 [1]) has a flat face in order to be installed in the pipework between PN16 and PN20 (ANSI150) flanges.
Page 28 HE MANUFACTURER IS NOT LIABLE FOR ANY DAMAGES TO THE QUANTOMETER DUE TO IMPROPER FILTRATION OF THE FLOWING GAS The user of the meter should pay special attention to some risk related to gas flow changes. If for a longer time, after commissioning, the flow in the piping was relatively low the impuri- ties (e.g.

Page 33 NOTE ! CLFK-04 & CLFW-04 transmitters must not be used interchangeably. Index head is adapted to one type of transmitter only. CWSL Encoder (option) CWSL Encoder can be connected to the optional mechanical output. There are 3 ver- sions of (optional) Encoders available: CWSL-N, CWSL-A, CWSL-M (Fig. 23). Data sent from CWSL-N are equal to data on the index.
Page 34 In order to convert gas volume from operating into base conditions it is often required (or recommended) to use electronic volume converters. Common S.A. is also the manufactur- er of such devices, e.g. volume correctors CMK-03 (VPTZ), CRS-03 (VTZ) and data loggers CRI-02.
