VYMPEL-500

Vympel-500 flow meter

The Vympel-500 is a high-precision, ultrasonic multi-meter designed to measure the flow rate and volume of natural gas and other gaseous media. This flowmeter has eight independent “sensor-to-sensor” chord measuring channels. The measurement of the target media’s integral velocity along the chords makes it possible to obtain detailed information about the nature of the flow, while taking into account its distribution profile for the final flow rate calculation.
The device is equipped with an eight-channel electronic unit constructed using a modern low-power element base. The instrument’s software provides for a graphic display of all current measurement status information in real time and of diagnostic information about the electronic unit’s hardware status. The Vympel-500 can be used for the commercial gas metering at gas stations with pipe diameters of up to 1400 mm and at a pressures up to 25 MPa.

Application fields

  • multi-line gas metering stations
  • single-line gas metering stations with pipe diameters up to 1400 mm
  • gas distribution stations
  • technological facilities for metering associated gas, flare gas and other gases

Measuring circuit:

The flanged flow-metering transmitter of the Vympel-500 has two, four or eight measuring channels oriented in one or two planes.

One is the «working» plane, the other is a backup. If necessary, the second measuring plane can be used to engage the second electronics unit in order to duplicate/verify the readings of the first measuring unit. The four channels, arranged along the chords of the inner diameter of the pipeline, provide an optimal measurement of the flow profile, even in the presence of an asymmetry («swirl of the flow»).
