Rotary gas meters are positive displacement meters, designed to measure quantity of gas, for custody transfer or technical measurement applications.
The CGR-FX Meters are applied in measurement systems where high accuracy is required:
• Transportation and distribution of natural gas
• Primary and secondary measurements
• Control metering of natural gas and non aggressive technical gases in industry

COMMON Quantometer

CPT-01 Quantometer - FLANGE FITTING

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.

common CZAK-03

CZAK-03 Communication and Signalling Barrier

The CZAK-03 Communication and Signalling barrier is device designed for transmitting digital and analogue data as well as for power supplying EX equipment installed within the areas threatened by a risk of explosion. The device may co-operate with majority of “Ex devices” used in the gas industry and many other industry branches.

COMMON CMB-03

CMB-03 Telemetry Module

CMB-03 Telemetric Module is a universal compact device battery powered with intrinsic safe circuits. Considering the construction CMB-03 Telemetric Module can be directly connected to equipment inside the explosion zone.

Main advantage of the module is its power supply eliminating extra costs related to providing external power line. Standard supply allows to operate for 3 years with scheduled transmissions or for about 2 months with continuous readout.

common CTS-04

CTS-04 Data Transmiter

The universal CTS-04 transmitter is a battery-operated telemetry device with a built-in GSM module , which has an explosion-proof structure and can be installed in an explosion hazard zone. The task of the transmitter is to make an autonomous, cyclic reading of data from volume converters, pressure recorders, pulse recorders and other devices equipped with the RS-GAZ2 interface.

cmk-03-800x794

CMK-03 Electronic Volume Corrector

The CMK-03 calculator is a modern, high-class battery-powered measuring and billing device that fully meets the requirements of the MID directive. It combines the unique requirements of the Polish market with experience from the solutions of our devices sold on global markets. The calculator is intended for use in gas measurement, reduction and measurement stations. It can cooperate with any gas meter (e.g. rotor, turbine, ultrasonic) which provides information about the measured volume in the form of pulses. CMK-03 is the main battery-powered calculator with external power supply. Installed batteries ensure continuous, maintenance-free measurement and data recording for a minimum of 6 years.

common CRS-03

CRS-03 Data Logger

The CRS-03 Data Logger is dedicated to work with turbine, rotary and diaphragm gas meters equipped with low frequency reed contact pulse transmitter. Its main task is to record the measured volume of flowing gas in real conditions and assign the “peak hour”, i.e. maximum hourly gas consumption together with the moment of its occurance.

A built-in display, permanently active, enables accesspromptly to the most important information for the user.

Recorded information can be passed on via Text messages (built-in GSM module) as well as via OPTO-GAZ optical connection with a suitable optical interfacewhich additionally enables to configure the device locally.

ACCESSORIES

COMMON COGUSB-03

COGUSB-03 Optical Transmission Interface

The COGUSB-03 Optical Transmission Interface is designed to enable data transmission between the device inside the explosion hazard zone (e.g. CMK-02 Volume Corrector) and non-EX device equipped with USB port outside explosion hazard zone (e.g. laptop). Data transmission is based on two infrared diodes, one for sending and the other receiving data. Interface head should be placed on the OPTO-EYE port located in the read out device. Permanent magnet inside the head activates the superior port which allows to perform the transmission.

common Top Hat filters (cone type)
hat-filters-400x276

Top Hat filters (cone type)

Top Hat Filters (Temporary strainers) are designed for use during the commissioning or start-up period of installation. They protect the control equipment in the system from dirt, debris and any other foreign bodies that may pass through a new system. The Top Hat Filter is added to a new system at the time of installation and removed after the system has been cleansed. Top Hat Filters are easy to fit and are located between the mating flanges in the pipeline – If you are adding a Commissioning filter to a vertically installed meter, we recommend adding a filter to both the inlet and outlet.

common Three-way valve CKMT DN4

Three-way valve CKMT DN4

The CKMT DN4 three-way valve is used in petrochemical industry installations, in gas measurement systems and other installations. It can be used in rooms with a risk of explosion of vapors and gases of the A, B, C explosion groups, in group II of explosion-proof devices.

CGZW Single Chamber Orifice Flowmeter

CGZW Single Chamber Orifice Flowmeter

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.
