CPT-01 & CPT-01S
Quantometer
for secondary measurements
CPT-01 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 turbi- ne and rotary gas meters resulted in the development of indu- strial quantometers.
Taking into account our customers’ demands we created the instrument with excellent metrological characteristics and opera- ting performance close to performances of the turbine gas meters designed for custody transfer measurements. Other advantages of the CPT-01 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-01 Quantometers are well accepted by our domestic and foreign customers.

Pressure loss
CPT-01 Quantometer for Secondary Measurements
Pressure drop during the gas flow through the quantometers is determined for air at atmospheric conditions. Maximum value of the Apmax pressure drop for every CPT-01 Quantometer is given in table 1. This value was established during tests carried out at Q with air (p = 1,2kg/m3 density). At real condi- tions Appressure drop may be calculated with the following formula:
Definitions:
maximum flow of the quantometer (according to Table 1) [m3/h] flow at real conditions [m/h]
