Description

GAS METER (CPT-01 QUANTOMETER)

CPT Quantometers have been designed in order to provide users with reliable and inexpensive measuring instruments for secondary flow measurements. Other advantages of the CPT Quantometers are as follows:

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 elementbetween measuring cartridge and the index
• index head

• Aluminium housing, sandwich version
• 1 off LF reed contact switch in the index head
• 1 off pressure measurement tap in the meter body 
• Self lubricated bearings
• Factory calibration with air at atmospheric conditions (calibration certificate on request)

MEASUREMENT OUTPUTS

The operating pressure (reference pressure) can be taken from the pressure tap, marked pr, located on one side of the meter body.

PULSE SENSORS

The mechanical index unit indicates the actual volume of the measured gas at operating temperature and operating pressure. It can be rotated axially by 350° in order to facilitate the readings and enable easier connection of pulse sensor plugs. The index unit is provided with one low frequency LFK reed contact pulse transmitter, as a standard. On request the index may be equipped with:

• LFI inductive pulse sensor (NAMUR)
• HF inductive pulse sensor (NAMUR)

The CPT Quantometers may be provided with up to 7 pulse sensors:

The turbine wheel, as a standard, is made of aluminium. This allows to provide each CPT Quantometer with one HF3 inductive pulse sensor. There are no extra costs due to the replacement of the turbine wheel.
