CGT series turbine gas meters are flow meters designed to measure quantity of gases. The meters are mainly used for gas flow ranges from 6.5 up to 6500 m3/h. The CGT series gas meters are applied in measurement systems where high accuracy is required:

• transportation of natural gas
• primary and secondary measurements
• control metering of the natural gas and non aggressive technical gases in industry
• flow measurement for technical purposes

The meters may be applied for measurements of aggressive gases. Any application of that kind should be individually proved and agreed between the client and COMMON S.A.

CGZW Single Chamber Orifice Flowmeter with Removable Orifice Plate

The CGZW Orifice Flowmeters are designed for volume measurement of flowing gas, and may be used for the following purposes:

• custody transfer measurements of flowing gas,
• flow measurements in transmission and distribution gas pipelines,
• control measurements of flowing gas

The operating principle is based on the pressure drop caused by a contraction. Basing on the differential pressure of the flow the gas volume may be determined.

The CGZW Flowmeters are manufactured as single chamber fittings with removable orifice plate, and appropriate meter tubes. The fitting construction enables to access the orifice plate easily and quickly for inspection and replacement. lt is not necessary to disassemble and spread flanges. One of characteristic features of the CGZW Flowmeters is easy control of leakages around the orifice plate.

CPT Quantometers have been designed in order to provide our customers with reliable and inexpensive measuring instruments for secondary flow measurements. Our great experience in designing and manufacturing of turbine and rotary gas meters resulted in the development of industrial quantometers.
Taking into account our customers’ demands we created the instrument with excellent metrological characteristics and operating performance close to performances of the turbine gas meters designed for custody transfer measurements.
Other advantages of the CPT Quantometers are as follows: high quality, easy maintenance, wide range of external devices that can co-operate with the quantometers, e.g. volume correctors, data loggers, data transmission systems.
Due to that the CPT Quantometers are well accepted by our domestic and foreign customers.

The basic components of the CPT Quantometer are as follows:

• pressure resistant meter body
• inlet flow conditioner
• measuring cartridge with the turbine wheel
• magnetic coupling as the transferring element between measuring cartridge and the index
• index head

The microcomputer CMK-02 Volume Corrector is supplied either form batteries or from mains, and may be used in gas measuring systems where high measurement accuracy , reliability and servicing simplicity is required at competitive price.

The features of the CMK-02 corrector, including the possibility of extending with additional measurements, enable to apply the device in measuring systems where, till now, it was necessary to use much more expensive flow computers. The device complies with domestic and European Union standards.

The CMK-02 Volume Corrector is the device oparating in 3V technology, made with the use of double side surface mounting (SMT).
