Rotary Gas Volume Convert

Основные технические данные

Gas volume accuracy at base conditions
0,05·Q max ≤ Q ≤ Q max, ± 2,25 % absolute error;
Q min ≤ Q < 0,05·Q max, ± 1,25 % absolute error;

Temperature scales range: -30 to +50 ºC (with a ± 0,4 °С absolute error)

Meaturement gas absolute pressure of reduced error ± 0,1%(for K.V.R. only) up to a 0.2 / 0.5 / 0.7 / 1.3 MPa

  Gas compressibility factor: NX19 mod. or GERG 91 mod

Archives: temporary, daily, monthly, emergency situations, interventions, corrector work interference, prompt

  Battery lifetime: 8 years

 Three-level data protection

Remote input of gas parameters

 Ambient temperature from -25 to +55 ºC

 Explosion-proof shell

 IP65 Protection Class

Advantages

Calculation of natural gas volume consumption and other non-aggressive gases and bringing them to standard conditions in accordance with ÃÎÑÒ 2939-63.

Key Features

  • Rotary gas meter with pTZ correction (correction for temperature, pressure and compressibility factor)
  • Rotary gas meter with TZ correction (correction by temperature and compressibility factor)

Major Benefits

  • Consist of rotary meter and gas volume connection, which significantly increases the security of the accounting node.
  • Lets you instantly determine the state of motion of the medium in the pipeline.
  • Provides dynamic accuracy when operating in pulse mode.
  • Removes unregulated costs of gas volumes below Qmin. Demanding for the presence of straight sections before and after the complex.
  • Extended range of measured volumetric flow.
  • Autonomous power supply.
  • Meets the requirements of the technical regulations of equipment and protective systems intended for use in potentially explosive atmospheres, approved by the Resolution of the Cabinet of Ministers of 28.12.16 № 1055 (Module B (type examination) and module E) (conformity to type based on product quality assurance) 2G Ex ib IIA T4 Gb
