GAS METERS
CPT-01 G250
CPT-01 G160
CPT-01 QUANTOMETER
Reliable and inexpensive measuring instruments for secondary ow
measurements.
We created the instrument with excellent metrological characteristics and
operating performance close to performances of the turbine gas meters
designed for custody transfer measurements.
The CPT Quantometers are high quality and easy maintenance with wide
range of external devices that can co-operate with the quantometers, e.g.
volume correctors, data loggers, data transmission systems. Therefore the CPT
Quantometers are well accepted by our domestic and foreign customers.
The basic components of the CPT Quantometer are as follows:
lpressure resistant meter body
linlet ow conditioner
lmeasuring cartridge with the turbine wheel
lmagnetic coupling as the transferring elementbetween measuring
lcartridge and the index
lindex head
l range extended to include 1 inch,1.¼ inch, 1.½ inch, 2 inch screwed options
l meter for Biogas available
l Atex approved index head
l meter tested to 2004/22/EC MID, Annex-MI-002 Class;1.5
MEASUREMENT OUTPUTS
The operating pressure (reference pressure) can be taken from the pressure tap,
marked pr, located on the 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 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.
CPT-01 G40
The CPT Quantometers may be provided
with up to 7 pulse sensors:
LFK
low frequency reed contact pulse sensor
LFK 1, LFK 2
LFI
low frequency inductive pulse sensor
LFI 1, LFI 2
