Vympel-15000

Grade 1 gas volume flow rate standard in value range of 30...20000 m3/h
The grade 1 gas volume flow rate standard is designed for reproduction of volume flow rate units in a range of 30-20000 m3, communicating their size to measuring instruments (flow meters), and R&D in their metrological supply.
The Vympel-15000 standard is bound to the Russian National Primary Flow Unit Standard. The standard has an error limit of 0.3% and allows for calibration and verification of flow meters with form factors Du50-Du500 with an error limit of 0.5%. The operating environment used is air under standard conditions.

Operation principle:

The installation includes the following units and parts:

Testing section

The testing section consists of the verified instrument installation spot, a set of straight sections equipped with outlets for air flow parameter measuring sensors.

Measuring section

The measuring section includes six sets of measuring wires (DN of measuring pipelines: 80, 150, 200, 300, 100, 500) with possible installation of reference ultrasonic flow meters with corresponding DN on each of them.
Every reference flow meter is a flange measuring section with piezoelectric sensors (8 or 16) and pressure sensor, the measured medium temperature sensor is installed in the output straight section.
The reference flow meter electronic units have a flow metering channel, temperature metering channel, pressure metering channel, and provide data output on operating flow and flow converted to standard conditions. The measuring section is located between the testing section and the flow generator receiver.

Receiver

The receiver is rectangular in shape, provides damping of the verification medium flow parameters. For easy mounting and dismounting of reference flow meters, it can be moved with ROCLA type manual cars, forklifts, overhead cranes, etc.

Instrument set and auxiliary equipment

The instrument and auxiliary equipment set is designed for monitoring and measuring the verification medium parameters during verification.
The instruments include:
  • flow difference sensor ДП-19 КРАУ5.183.019-17 installed on a measuring line, connected to the reference meter and verified flow meter;
  • pressure and pressure difference sensor programming device КРАУ5.139.011;
The auxiliary equipment includes a set of information and power cables and a set of plugs.

Flow generator

The flow generator is based on type K3G8710-AR03-01 three-phase centrifugal fans with frequency adjustment, 7870 W (4 pcs.).
The fan rate is adjusted automatically and set from the PC operator workplace to ensure necessary head-capacity curve.

Power supply cabinet

The power supply cabinet supplies power to the equipment, including the three-phase centrifugal fans in the flow generator.

PC operator workplace and software

The PC operator workplace with special software for control and setting the installation operation parameters, gathering data from the verified and reference flow meters and auxiliary equipment, processing and storage of data and reporting is placed near the installation.

Software

The software of the hardware support installation is autonomous (PC-based software). The verified measuring instruments are connected through closed communication channels.
The measured units are converted and measurement data is processed using the internal hardware and software. The software and gathered data are stored in the internal storage device (PC hard disk drive). The software environment is constant, there are no means or user shell for programming or modification of software.
The installation’s software is designed for gathering, processing and presenting information on verification. The software allows for:
  • automatic or manual verification;
  • saving intermediate and final results of verification in the database;
  • export the verification results in the verification report format;
  • loading the verification or study results from the database with the flow meter serial number;
  • automaic identification and entering the calibration factors in the verified flow meters.
The software for the installation is divided into:
  • metrologically significant part;
  • metrologically non-significant part.
The software is divided within the code at the programming language level. The metrologically significant software includes:
  • software modules involved in processing (calculation) of the measurement results or affecting them;
  • software modules involved in gathering or presenting measurement information, its storage, transfer, identification, protection of software and data;
  • software parameters involved in calculations and affecting measurement results.
The metrologically insignificant software include the graphic user interface — terminal program (graphical application for Windows).

Installation operation mode

The installation operation modes are set with the stand automation control program controlling the flow generator fans.
