4-channel flowmeters for enhanced accuracy

High accuracy ultrasonic flow meter Energoflow GFE-404

HIGH ACCURACY ULTRASONIC FLOW METERS Energoflow GFE-404

Overview

Four-channel Ultrasonic Gas Flow Meter Energoflow GFE-404 is MID certified, ATEX specially designed for applications where very high accuracy is required, e.g. for custody transfer measurement of natural gas. The standard version provides an accuracy of 0.5%, flow meters with an accuracy of 0.2% can be supplied under order. Ultrasonic Gas Flow Meter Energoflow GFE-404 certified to OIML R137 class 0.5 by PTB.

The flow meters provide accurate and reliable measurement of the gas flow rate in the pipeline in both directions within the range from 0.1 to 30 m / c. The flow meters are available in a wide range of sizes.

The flow meters are pre-calibrated on air as per customer's requirements, pre-calibration on natural gas is provided under special order.

Energoflow GFE-404 C can be accessed remotely via PC. Using special software, it is possible to display the following data as per customer’s choice:
  • Measurement results of direction and speed of gas flow, current flow, accumulated total volume;
  • The waveform of the signal passing through the acoustic channel;
  • Configuration options and settings of the flow meter;
  • Clock readings and calendar;
  • Archive data.
