Energoflow LF-131H Liquid Flow Meter


Table of Contents

Energoflow LF-131H Liquid Flow Meter for applications where the medium pressure is very high, eg. measuring the flow of strata l water, we have developed the model LF-131H. The device can be used for bidirectional measurement of the flow of mediums at pressure as high as 40 Mpa. These Liquid Flow Meter LF-131H are available in two versions – with an integrally mounted or with a standard remotely installed Electronics unit.

Electronics unit having a built-in battery which provides full autonomous functionality for more than four years, The LF-131H Liquid Flow Meter is widely used in the downstream applications in the Oil & Gas industry, eg. at extraction wells since they are rugged and can handle aggressive liquids at such high pressure. They are also used for applications like cementing of wells and measurement of the flow of chemicals injected into wells at high pressure.

Ultrasonic gas flow meters ENERGOFLOW GF

Energoflow AG can provide flow metering solutions for the whole spectrum of applications required by the Gas sector.

Our flow meters can operate in a wide range of ambient conditions – we provide flow metering solution for very cold regions (ambient temperature -60 deg. C) as well as for hot locations (ambient temperature +70 deg. C). The Energoflow GF series of gas flow meters is designed to improve reliable and accurate measurement of gas flow in pipelines using the pulse-time method. These flow meters can be used for flow monitoring and measurement of air, natural gas, industrial gases, fuel gas etc. over a vast range of process conditions:

  • For flow speeds as low as 1 m/s and as high as 70 m/s;
  • For ambient temperatures as low as -65 C and as high as +70 deg. C;
  • In hazardous areas and hard to access locations;
  • When the pressure in the pipeline is as high as 160

The major advantages of the Energoflow GF series gas flow meters are:

  1. No obstruction to the flow and zero pressure loss;
  2. No moving parts and no mechanical wear or tear;
  3. Easy installation and simplicity of use;
  4. Easy integration into all kinds of process management systems;
  5. High accuracy, large turn-down ratio, reliable

Energoflow GF series flow meters 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 flow, current flow rate, progressive 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

We supply flow meters of various sizes, with different types of process connections, and for a wide range of ambient and process temperatures and pressure ratings.

The flow meters can be spool type or hot tapped type, depending on the application.
